Indeed, many applications, which propose entertaining audio-visual experiences with the objective of musical creation, are available today for different supports (game consoles, computers, cell phones). The originality of this field is the use of the gameplay of video games applied to music composition. Thus, composing music using interfaces but also cognitive logics that we qualify as "a-musicological" seem to us particularly interesting from the perspective of musical digital organology. This field raises questions about the representation of sound and musical structures and develops new instrumental gestures and strategies of musical composition. We will try in this article to define the characteristics of this field by highlighting some historical milestones (abstract cinema, game theory in music, actions, and graphic scores) as well as the novelties brought by digital technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audio-games" title="audio-games">audio-games</a>, <a href="https://publications.waset.org/abstracts/search?q=video%20games" title=" video games"> video games</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20generated%20music" title=" computer generated music"> computer generated music</a>, <a href="https://publications.waset.org/abstracts/search?q=gameplay" title=" gameplay"> gameplay</a>, <a href="https://publications.waset.org/abstracts/search?q=interactivity" title=" interactivity"> interactivity</a>, <a href="https://publications.waset.org/abstracts/search?q=synesthesia" title=" synesthesia"> synesthesia</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20interfaces" title=" sound interfaces"> sound interfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=relationships%20image%2Fsound" title=" relationships image/sound"> relationships image/sound</a>, <a href="https://publications.waset.org/abstracts/search?q=audiovisual%20music" title=" audiovisual music"> audiovisual music</a> </p> <a href="https://publications.waset.org/abstracts/152518/digital-musical-organology-the-audio-games-the-question-of-a-musicological-interfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152518.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1149</span> Hydration of Protein-RNA Recognition Sites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amita%20Barik">Amita Barik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ranjit%20Prasad%20Bahadur"> Ranjit Prasad Bahadur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigate the role of water molecules in 89 protein-RNA complexes taken from the Protein Data Bank. Those with tRNA and single-stranded RNA are less hydrated than with duplex or ribosomal proteins. Protein-RNA interfaces are hydrated less than protein-DNA interfaces, but more than protein-protein interfaces. Majority of the waters at protein-RNA interfaces makes multiple H-bonds; however, a fraction does not make any. Those making Hbonds have preferences for the polar groups of RNA than its partner protein. The spatial distribution of waters makes interfaces with ribosomal proteins and single-stranded RNA relatively ‘dry’ than interfaces with tRNA and duplex RNA. In contrast to protein-DNA interfaces, mainly due to the presence of the 2’OH, the ribose in protein-RNA interfaces is hydrated more than the phosphate or the bases. The minor groove in protein-RNA interfaces is hydrated more than the major groove, while in protein-DNA interfaces it is reverse. The strands make the highest number of water-mediated H-bonds per unit interface area followed by the helices and the non-regular structures. The preserved waters at protein-RNA interfaces make higher number of H-bonds than the other waters. Preserved waters contribute toward the affinity in protein-RNA recognition and should be carefully treated while engineering protein-RNA interfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=h-bonds" title="h-bonds">h-bonds</a>, <a href="https://publications.waset.org/abstracts/search?q=minor-major%20grooves" title=" minor-major grooves"> minor-major grooves</a>, <a href="https://publications.waset.org/abstracts/search?q=preserved%20water" title=" preserved water"> preserved water</a>, <a href="https://publications.waset.org/abstracts/search?q=protein-RNA%20interfaces" title=" protein-RNA interfaces"> protein-RNA interfaces</a> </p> <a href="https://publications.waset.org/abstracts/42932/hydration-of-protein-rna-recognition-sites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42932.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1148</span> Development of Sound Tactile Interface by Use of Human Sensation of Stiffness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Doi">K.

In this study, we developed a sound tactile interface that makes use of the human sensation of stiffness. The interface comprises eight elastic objects having varying degrees of stiffness. Each elastic object is shaped like a column. When people with and without hearing disabilities press each elastic object, different sounds are produced depending on the stiffness of the elastic object. The types of sounds used were “Do Re Mi sounds.” The interface has a major advantage in that people with or without hearing disabilities can play with it. We found that users were able to recognize the hardness sensation and relate it to the corresponding Do Re Mi sounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tactile%20sense" title="tactile sense">tactile sense</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20interface" title=" sound interface"> sound interface</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness%20perception" title=" stiffness perception"> stiffness perception</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic%20object" title=" elastic object"> elastic object</a> </p> <a href="https://publications.waset.org/abstracts/13051/development-of-sound-tactile-interface-by-use-of-human-sensation-of-stiffness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13051.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1147</span> Sound Selection for Gesture Sonification and Manipulation of Virtual Objects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Bressolette">Benjamin Bressolette</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C2%B4ebastien%20Denjean"> S´ebastien Denjean</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincent%20Roussarie"> Vincent Roussarie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mitsuko%20Aramaki"> Mitsuko Aramaki</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C3%B8lvi%20Ystad"> Sølvi Ystad</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Kronland-Martinet"> Richard Kronland-Martinet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New sensors and technologies – such as microphones, touchscreens or infrared sensors – are currently making their appearance in the automotive sector, introducing new kinds of Human-Machine Interfaces (HMIs). The interactions with such tools might be cognitively expensive, thus unsuitable for driving tasks. It could for instance be dangerous to use touchscreens with a visual feedback while driving, as it distracts the driver’s visual attention away from the road. Furthermore, new technologies in car cockpits modify the interactions of the users with the central system. In particular, touchscreens are preferred to arrays of buttons for space improvement and design purposes. However, the buttons’ tactile feedback is no more available to the driver, which makes such interfaces more difficult to manipulate while driving. Gestures combined with an auditory feedback might therefore constitute an interesting alternative to interact with the HMI. Indeed, gestures can be performed without vision, which means that the driver’s visual attention can be totally dedicated to the driving task. In fact, the auditory feedback can both inform the driver with respect to the task performed on the interface and on the performed gesture, which might constitute a possible solution to the lack of tactile information. As audition is a relatively unused sense in automotive contexts, gesture sonification can contribute to reducing the cognitive load thanks to the proposed multisensory exploitation. Our approach consists in using a virtual object (VO) to sonify the consequences of the gesture rather than the gesture itself. This approach is motivated by an ecological point of view: Gestures do not make sound, but their consequences do. In this experiment, the aim was to identify efficient sound strategies, to transmit dynamic information of VOs to users through sound. The swipe gesture was chosen for this purpose, as it is commonly used in current and new interfaces. We chose two VO parameters to sonify, the hand-VO distance and the VO velocity. Two kinds of sound parameters can be chosen to sonify the VO behavior: Spectral or temporal parameters. Pitch and brightness were tested as spectral parameters, and amplitude modulation as a temporal parameter. Performances showed a positive effect of sound compared to a no-sound situation, revealing the usefulness of sounds to accomplish the task. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auditory%20feedback" title="auditory feedback">auditory feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=gesture%20sonification" title=" gesture sonification"> gesture sonification</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20perception" title=" sound perception"> sound perception</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20object" title=" virtual object"> virtual object</a> </p> <a href="https://publications.waset.org/abstracts/54374/sound-selection-for-gesture-sonification-and-manipulation-of-virtual-objects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54374.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1146</span> Investigation of Al/Si, Au/Si and Au/GaAs Interfaces by Positron Annihilation Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulnasser%20S.%20Saleh">Abdulnasser S. Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The importance of metal-semiconductor interfaces comes from the fact that most electronic devices are interconnected using metallic wiring that forms metal–semiconductor contacts. The properties of these contacts can vary considerably depending on the nature of the interface with the semiconductor. Variable-energy positron annihilation spectroscopy has been applied to study interfaces in Al/Si, Au/Si, and Au/GaAs structures. A computational modeling by ROYPROF program is used to analyze Doppler broadening results in order to determine kinds of regions that positrons are likely to sample. In all fittings, the interfaces are found 1 nm thick and act as an absorbing sink for positrons diffusing towards them and may be regarded as highly defective. Internal electric fields were found to influence positrons diffusing to the interfaces and unable to force them cross to the other side. The materials positron affinities are considered in understanding such motion. The results of these theoretical fittings have clearly demonstrated the sensitivity of interfaces in any fitting attempts of analyzing positron spectroscopy data and gave valuable information about metal-semiconductor interfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interfaces" title="interfaces">interfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor" title=" semiconductor"> semiconductor</a>, <a href="https://publications.waset.org/abstracts/search?q=positron" title=" positron"> positron</a>, <a href="https://publications.waset.org/abstracts/search?q=defects" title=" defects "> defects </a> </p> <a href="https://publications.waset.org/abstracts/46927/investigation-of-alsi-ausi-and-augaas-interfaces-by-positron-annihilation-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46927.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1145</span> Acoustic Performance and Application of Three Personalized Sound-Absorbing Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fangying%20Wang">Fangying Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Sanming"> Zhang Sanming</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni%20Qian"> Ni Qian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, more and more personalized sound absorbing materials have entered the Chinese room acoustical decoration market.

Multilayer porous materials are dominant in room absorber. Multilayer viscoelastic materials are the basic parts in underwater absorption coating. In most cases, the one-way sound absorption performance of multilayer material is concentrated according to the sound source site. But the two-way sound absorption performance is also necessary to be known in some special cases which sound is produced in both sides of the material and the both sides especially might contact with different media. In this article, this kind of case was research. The multilayer material was composed of viscoelastic layer and steel plate and the porous layer. The two sides of multilayer material contact with water and air, respectively. A theory model was given to describe the sound propagation and impedance in multilayer absorption material. The two-way sound absorption properties of several multilayer materials were calculated whose two sides all contacted with different media. The calculated results showed that the difference of two-way sound absorption coefficients is obvious. The frequency, the relation of layers thickness and parameters of multilayer materials all have an influence on the two-way sound absorption coefficients. But the degrees of influence are varied. All these simulation results were analyzed in the article. It was obtained that two-way sound absorption at different frequencies can be promoted by optimizing the configuration parameters. This work will improve the performance of underwater sound absorption coating which can absorb incident sound from the water and reduce the noise radiation from inside space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=different%20media" title="different media">different media</a>, <a href="https://publications.waset.org/abstracts/search?q=multilayer%20material" title=" multilayer material"> multilayer material</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20coating" title=" sound absorption coating"> sound absorption coating</a>, <a href="https://publications.waset.org/abstracts/search?q=two-way%20sound%20absorption" title=" two-way sound absorption"> two-way sound absorption</a> </p> <a href="https://publications.waset.org/abstracts/33628/research-on-the-two-way-sound-absorption-performance-of-multilayer-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33628.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">542</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1141</span> Experimental Study of the Sound Absorption of a Geopolymer Panel with a Textile Component Designed for a Railway Corridor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ludmila%20Fridrichov%C3%A1">Ludmila Fridrichová</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Kn%C3%AD%C5%BEek"> Roman Knížek</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20N%C4%9Bme%C4%8Dek"> Pavel Němeček</a>, <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Ewa%20Buczkowska"> Katarzyna Ewa Buczkowska</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The design of the sound absorption panel, which consists of three layers, is presented in this study. The first layer of the panel is perforated and provides sound transmission to the inner part of the panel. The second layer is composed of a bulk material whose purpose is to absorb as much noise as possible. The third layer of the panel has two functions: the first function is to ensure the strength of the panel, and the second function is to reflect the sound back into the bulk layer. Experimental results have shown that the size of the holes in the perforated panel affects the sound absorption of the required frequency. The percentage of filling of the perforated area affects the quantity of sound absorbed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption" title="sound absorption">sound absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=railway%20corridor" title=" railway corridor"> railway corridor</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20waste" title=" textile waste"> textile waste</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20fibres" title=" natural fibres"> natural fibres</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a> </p> <a href="https://publications.waset.org/abstracts/193093/experimental-study-of-the-sound-absorption-of-a-geopolymer-panel-with-a-textile-component-designed-for-a-railway-corridor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193093.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">14</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1140</span> Development of Prediction Tool for Sound Absorption and Sound Insulation for Sound Proof Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yoshio%20Kurosawa">Yoshio Kurosawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Takao%20Yamaguchi"> Takao Yamaguchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High frequency automotive interior noise above 500 Hz considerably affects automotive passenger comfort.

In order to minimize the transmission of floor impact sound, flooring structures are used in which an insulating material, 30 mm thickness pad of EPS or EVA, is sandwiched between a concrete slab and the finished mortar. Generally, a single-material pad used for insulation has a heavyweight impact sound level of 44~47 dB with 210 mm thickness slab. This study provides an analysis of the floor impact sound insulation performance using thermoplastic poly urethane (TPU), ethylene vinyl acetate (EVA), and expanded polystyrene (EPS) materials with buffering performance.

Murray Schafer, the author who originally developed this concept, highlights the need for a greater recognition of sound reality, through the selection and differentiation of sounds, contributing to a tuning of the world and to the balance and well-being of humanity. According to some authors sound environment, produced and created in various ways, provides various sources of information, contributing to the orientation of the human being, alerting and manipulating him during his daily journey, like small notifications received on a cell phone or other device with these features. In this way, it becomes possible to give sound its due importance in relation to the processes of individual representation, in manners of social, professional and emotional life. Ensuring an individual representation means providing the human being with new tools for the long process of reflection by recognizing his environment, the sounds that represent him, and his perspective on his respective function in it. In order to provide more information about the importance of the sound environment inherent to the individual reality, one introduces the term sound instance, in order to refer to the whole sound field existing in the individual's life, which is divided into four distinct subfields, but essential to the process of individual representation, called sound matrix, sound cycles, sound traces and sound interference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sound%20instance" title="sound instance">sound instance</a>, <a href="https://publications.waset.org/abstracts/search?q=soundscape" title=" soundscape"> soundscape</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20art" title=" sound art"> sound art</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a>, <a href="https://publications.waset.org/abstracts/search?q=composition" title=" composition"> composition</a> </p> <a href="https://publications.waset.org/abstracts/155181/sound-instance-art-perception-and-composition-through-soundscapes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155181.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1135</span> Analysis of Sound Loss from the Highway Traffic through Lightweight Insulating Concrete Walls and Artificial Neural Network Modeling of Sound Transmission</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Tosun">Mustafa Tosun</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevser%20Dincer"> Kevser Dincer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, analysis on whether the lightweight concrete walled structures used in four climatic regions of Turkey are also capable of insulating sound was conducted.

The ANN was trained and tested by using MATLAB toolbox on a personal computer. ANN input parameters that used were thickness of lightweight concrete wall, frequency and density of lightweight concrete wall, while the transmitted sound was the output parameter. When the results of the TS analysis and those of ANN modeling are evaluated together, it is found from this study, that sound transmit loss increases at higher frequencies, higher wall densities and with larger wall cross sections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neuron%20network" title="artificial neuron network">artificial neuron network</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20concrete" title=" lightweight concrete"> lightweight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20insulation" title=" sound insulation"> sound insulation</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20transmit%20loss" title=" sound transmit loss"> sound transmit loss</a> </p> <a href="https://publications.waset.org/abstracts/41076/analysis-of-sound-loss-from-the-highway-traffic-through-lightweight-insulating-concrete-walls-and-artificial-neural-network-modeling-of-sound-transmission" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41076.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">252</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1134</span> The Optimization Design of Sound Absorbing for Automotive Interior Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Un-Hwan%20Park">Un-Hwan Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Hyeok%20Heo"> Jun-Hyeok Heo</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Sung%20Lee"> In-Sung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Hyeon%20Oh"> Tae-Hyeon Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae-Gyu%20Park"> Dae-Gyu Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nonwoven fabric such as an automobile interior material becomes consists of several material layers required for the sound-absorbing function.

The developed mathematical model and statistical analysis provided a critical analysis of the simultaneous interactive effects of the independent variables indicating that the developed quadratic models were highly accurate and predictive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental%20design" title="experimental design">experimental design</a>, <a href="https://publications.waset.org/abstracts/search?q=octane" title=" octane"> octane</a>, <a href="https://publications.waset.org/abstracts/search?q=speed%20of%20sound" title=" speed of sound"> speed of sound</a>, <a href="https://publications.waset.org/abstracts/search?q=toluene" title=" toluene"> toluene</a> </p> <a href="https://publications.waset.org/abstracts/78076/measurement-and-prediction-of-speed-of-sound-in-petroleum-fluids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78076.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1130</span> The Design Optimization for Sound Absorption Material of Multi-Layer Structure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Un-Hwan%20Park">Un-Hwan Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Hyeok%20Heo"> Jun-Hyeok Heo</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Sung%20Lee"> In-Sung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Hyeon%20Oh"> Tae-Hyeon Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae-Kyu%20Park"> Dae-Kyu Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sound absorbing material is used as automotive interior material. Sound absorption coefficient should be predicted to design it. But it is difficult to predict sound absorbing coefficient because it is comprised of several material layers. So, its targets are achieved through many experimental tunings. It causes a lot of cost and time. In this paper, we propose the process to estimate the sound absorption coefficient with multi-layer structure. In order to estimate the coefficient, physical properties of each material are used. These properties also use predicted values by Foam-X software using the sound absorption coefficient data measured by impedance tube. Since there are many physical properties and the measurement equipment is expensive, the values predicted by software are used. Through the measurement of the sound absorption coefficient of each material, its physical properties are calculated inversely. The properties of each material are used to calculate the sound absorption coefficient of the multi-layer material. Since the absorption coefficient of multi-layer can be calculated, optimization design is possible through simulation. Then, we will compare and analyze the calculated sound absorption coefficient with the data measured by scaled reverberation chamber and impedance tubes for a prototype. If this method is used when developing automotive interior materials with multi-layer structure, the development effort can be reduced because it can be optimized by simulation. So, cost and time can be saved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20material" title="sound absorption material">sound absorption material</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20impedance%20tube" title=" sound impedance tube"> sound impedance tube</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20coefficient" title=" sound absorption coefficient"> sound absorption coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20design" title=" optimization design"> optimization design</a> </p> <a href="https://publications.waset.org/abstracts/82871/the-design-optimization-for-sound-absorption-material-of-multi-layer-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82871.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">288</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1129</span> Acoustic Finite Element Analysis of a Slit Model with Consideration of Air Viscosity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Sasajima">M.

In recent years, there have been many studies on the method of separating signals by using masking, but most of the separation methods must be operated under the condition of a known number of sound sources. Such methods cannot be used for real-time applications. In our method, this paper uses Circular-Integrated-Cross-Spectrum to estimate the statistical histogram distribution of the direction of arrival (DOA) to obtain the number of sound sources and sound in the mixed-signal Source direction. In calculating the relevant parameters of the ring integrated cross-spectrum, the phase (Phase of the Cross-Power Spectrum) and phase rotation factors (Phase Rotation Factors) calculated by the cross power spectrum of each microphone pair are used. In the part of separating speech, it uses the DOA weighting and shielding separation method to calculate the sound source direction (DOA) according to each T-F unit (time-frequency point). The weight corresponding to each T-F unit can be used to strengthen the intensity of each sound source from the T-F unit and reduce the influence of the remaining sound sources, thereby achieving voice separation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=real-time" title="real-time">real-time</a>, <a href="https://publications.waset.org/abstracts/search?q=spectrum%20analysis" title=" spectrum analysis"> spectrum analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20source%20localization" title=" sound source localization"> sound source localization</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20source%20separation" title=" sound source separation"> sound source separation</a> </p> <a href="https://publications.waset.org/abstracts/128672/implementation-of-real-time-multiple-sound-source-localization-and-separation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128672.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1127</span> Toward a Measure of Appropriateness of User Interfaces Adaptations Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abderrahim%20Siam">Abderrahim Siam</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramdane%20Maamri"> Ramdane Maamri</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaidi%20Sahnoun"> Zaidi Sahnoun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of adaptive user interfaces (UI) presents for a long time an important research area in which researcher attempt to call upon the full resources and skills of several disciplines.

Sound can be considered as a wave phenomenon. A sound wave is a longitudinal wave where particles of the medium are temporarily displaced in a direction parallel to energy transport and then return to their original position. The vibration in a medium produces alternating waves of relatively dense and sparse particles –compression and rarefaction respectively. The resultant variation to normal ambient pressure is translated by the ear and perceived as sound. Today much importance is given to the acoustical environment. The noise sources are increased day by day and annoying level is strongly violated in different locations by traffic, sound systems, and industries. There is simple evidence showing that the high noise levels cause sleep disturbance, hearing loss, decrease in productivity, learning disability, lower scholastic performance and increase in stress related hormones and blood pressure. Therefore, achieving a pleasing and noise free environment is one of the endeavours of many a research groups. This can be obtained by using various techniques. One such technique is by using suitable materials with good sound absorbing properties. The conventionally used materials that possess sound absorbing properties are rock wool or glass wool. In this work, an attempt is made to use synthetic material in both fibrous and sheet form and use it for manufacturing of non-woven for sound absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustics" title="acoustics">acoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre" title=" fibre"> fibre</a>, <a href="https://publications.waset.org/abstracts/search?q=non-woven" title=" non-woven"> non-woven</a>, <a href="https://publications.waset.org/abstracts/search?q=noise" title=" noise"> noise</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20properties" title=" sound absorption properties"> sound absorption properties</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20absorption%20coefficient" title=" sound absorption coefficient"> sound absorption coefficient</a> </p> <a href="https://publications.waset.org/abstracts/66969/development-and-characterization-of-synthetic-non-woven-for-sound-absorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66969.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1123</span> Study of Buried Interfaces in Fe/Si Multilayer by Hard X-Ray Emission Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hina%20Verma">Hina Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Karine%20Le%20Guen"> Karine Le Guen</a>, <a href="https://publications.waset.org/abstracts/search?q=Renaud%20Dalaunay"> Renaud Dalaunay</a>, <a href="https://publications.waset.org/abstracts/search?q=Iyas%20Ismail"> Iyas Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Vita%20Ilakovac"> Vita Ilakovac</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean%20Pascal%20Rueff"> Jean Pascal Rueff</a>, <a href="https://publications.waset.org/abstracts/search?q=Yunlin%20Jacques%20Zheng"> Yunlin Jacques Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Jonnard"> Philippe Jonnard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To the extent of our knowledge, X-ray emission spectroscopy (XES) has been applied in the soft x-ray region (photon energy ≤ 2 keV) to study the buried layers and interfaces of stacks of nanometer-thin films. Now we extend the methodology to study the buried interfaces in the hard X-ray region (i.e., ≥ five keV). The emission spectra allow us to study the interactions between elements in the buried layers from the analysis of their valence states, thereby providing sensitive information about the physical-chemical environment of the emitting element in multilayers. We exploit the chemical sensitivity of XES to study the interfaces between Fe and Si layers in the Fe/Si multilayer from the Fe Kβ₂,₅ emission spectra (7108 eV). The Fe Kβ₅ emission line results from the electronic transition from occupied 3d to 1s levels (i.e., valence to core transition) and is hence sensitive to the chemical state of emitting Fe atoms. The comparison of emission spectra recorded for Fe/Si multilayer with Fe and FeSi₂ references reveal the formation of FeSi₂ at the Fe-Si interfaces inside the multilayer stack. The interfacial thickness was calculated to be 1.4 ± 0.2 nm by taking into consideration the intensity of Fe atoms emitted from the interface and the Fe layer. The formation of FeSi₂ at the interface was further confirmed by the X-ray diffraction and X-ray photoelectron spectroscopy done on the Fe/Si multilayer. Hence, we can conclude that the XES in the hard X-ray range could be used to study multilayers and their interfaces and obtain information both qualitatively and quantitatively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buried%20interfaces" title="buried interfaces">buried interfaces</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20X-ray%20emission%20spectroscopy" title=" hard X-ray emission spectroscopy"> hard X-ray emission spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20diffraction" title=" X-ray diffraction"> X-ray diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20photoelectron%20spectroscopy" title=" X-ray photoelectron spectroscopy"> X-ray photoelectron spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/136026/study-of-buried-interfaces-in-fesi-multilayer-by-hard-x-ray-emission-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136026.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1122</span> Prediction of Physical Properties and Sound Absorption Performance of Automotive Interior Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Un-Hwan%20Park">Un-Hwan Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Hyeok%20Heo"> Jun-Hyeok Heo</a>, <a href="https://publications.waset.org/abstracts/search?q=In-Sung%20Lee"> In-Sung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong-Jin%20Cho"> Seong-Jin Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae-Hyeon%20Oh"> Tae-Hyeon Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae-Kyu%20Park"> Dae-Kyu Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sound absorption coefficient is considered important when designing because noise affects emotion quality of car.
