A very less research has been done for rehabilitation of blindness for the blind people. This paper discusses the work that helps blind people for recognizing the basic shapes of the objects like circle, square, triangle, horizontal lines, vertical lines, diagonal lines and the wave forms like sinusoidal, square, triangular etc. This is largely achieved by using a digital camera, which is used to capture the visual information present in front of the blind person and a software program, which achieves the image processing operations, and finally the processed image is converted into sound. After the sound generation process, the generated sound is fed to the blind person through headphones for visualizing the imaginary image of the object. For visualizing the imaginary image of the object, it needs to train the blind person. Various training process methods had been applied for recognizing the object. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title="image processing">image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=pixel" title=" pixel"> pixel</a>, <a href="https://publications.waset.org/abstracts/search?q=pitch" title=" pitch"> pitch</a>, <a href="https://publications.waset.org/abstracts/search?q=loudness" title=" loudness"> loudness</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20generation" title=" sound generation"> sound generation</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20detection" title=" edge detection"> edge detection</a>, <a href="https://publications.waset.org/abstracts/search?q=brightness" title=" brightness"> brightness</a> </p> <a href="https://publications.waset.org/abstracts/14606/rehabilitation-of-the-blind-using-sono-visualization-tool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14606.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">388</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">5813</span> Robust Image Registration Based on an Adaptive Normalized Mutual Information Metric</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huda%20Algharib">Huda Algharib</a>, <a href="https://publications.waset.org/abstracts/search?q=Amal%20Algharib"> Amal Algharib</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Algharib"> Hanan Algharib</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mohammad%20Alqudah"> Ali Mohammad Alqudah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Image registration is an important topic for many imaging systems and computer vision applications. The standard image registration techniques such as Mutual information/ Normalized mutual information -based methods have a limited performance because they do not consider the spatial information or the relationships between the neighbouring pixels or voxels. In addition, the amount of image noise may significantly affect the registration accuracy. Therefore, this paper proposes an efficient method that explicitly considers the relationships between the adjacent pixels, where the gradient information of the reference and scene images is extracted first, and then the cosine similarity of the extracted gradient information is computed and used to improve the accuracy of the standard normalized mutual information measure. Our experimental results on different data types (i.e. CT, MRI and thermal images) show that the proposed method outperforms a number of image registration techniques in terms of the accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=image%20registration" title="image registration">image registration</a>, <a href="https://publications.waset.org/abstracts/search?q=mutual%20information" title=" mutual information"> mutual information</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20gradients" title=" image gradients"> image gradients</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20transformations" title=" image transformations"> image transformations</a> </p> <a href="https://publications.waset.org/abstracts/82815/robust-image-registration-based-on-an-adaptive-normalized-mutual-information-metric" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82815.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">248</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">5812</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.

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">5810</span> Biofeedback-Driven Sound and Image Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudio%20Burguez">Claudio Burguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Castell%C3%B3"> María Castelló</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikaela%20Pisani"> Mikaela Pisani</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcos%20Umpi%C3%A9rrez"> Marcos Umpiérrez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> BIOFEEDBACK exhibition offers a unique experience for each visitor, combining art, neuroscience, and technology in an interactive way. Using a headband that captures the bioelectric activity of the brain, the visitors are able to generate sound and images in a sequence loop, making them an integral part of the artwork. Through this interactive exhibit, visitors gain a deeper appreciation of the beauty and complexity of the brain. As a special takeaway, visitors will receive an NFT as a present, allowing them to continue their engagement with the exhibition beyond the physical space. We used the EEG Biofeedback technique following a closed-loop neuroscience approach, transforming EEG data captured by a Muse S headband in real-time into audiovisual stimulation. PureData is used for sound generation and Generative Adversarial Networks (GANs) for image generation. Thirty participants have experienced the exhibition. For some individuals, it was easier to focus than others. Participants who said they could focus during the exhibit stated that at one point, they felt that they could control the sound, while images were more abstract, and they did not feel that they were able to control them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=art" title="art">art</a>, <a href="https://publications.waset.org/abstracts/search?q=audiovisual" title=" audiovisual"> audiovisual</a>, <a href="https://publications.waset.org/abstracts/search?q=biofeedback" title=" biofeedback"> biofeedback</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=NFT" title=" NFT"> NFT</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroscience" title=" neuroscience"> neuroscience</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/161610/biofeedback-driven-sound-and-image-generation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161610.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">72</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">5809</span> Comparing the Effect of Virtual Reality and Sound on Landscape Perception</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Lindquist">Mark Lindquist</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents preliminary results of exploratory empirical research investigating the effect of viewing 3D landscape visualizations in virtual reality compared to a computer monitor, and how sound impacts perception. Five landscape types were paired with three sound conditions (no sound, generic sound, realistic sound). Perceived realism, preference, recreational value, and biodiversity were evaluated in a controlled laboratory environment. Results indicate that sound has a larger perceptual impact than display mode regardless of sound source across all perceptual measures. The results are considered to assess how sound can impact landscape preference and spatiotemporal understanding.

First, 'meta-diegetic' sound will be briefly explained followed by transition to “oneiric” sound. The representation of oneiric sound refers to a situation where film characters are experiencing some sort of an altered state of consciousness. Looking at an antlered state of consciousness in terms of human brain processes will point out to the cinematic ways of expression, which 'mimic' those processes.

Brand owners improve their brand images with the positive perceptions remaining in the consumers’ minds. In addition, they try to find the customers that are both emotionally and behaviourally faithful to themselves in order to set up long – term relationships. Therefore, the aim of this study is to analyse the effects of the brand image that has a very important role among relational marketing elements on the brand loyalty in terms of the variables such as the perceived value, the trust in brand and the brand satisfaction. In this context, a conceptual model was created to determine the effect of the brand image on the brand loyalty thanks to the Structural Equation Model (SEM). According to this aim and this model, the study was carried out in the scope of the data collected through the questionnaires in Konya with the method of convenience sampling. The results of the research showed that the brand image has positive significant effects on the perceived value and the trust in brand and that the trust in brand has positive significant effects on the brand satisfaction, and that the brand satisfaction has positive significant effects on the brand loyalty. Thus, the hypotheses that the brand image has direct effects on the perceived value and the trust in brand and that the trust in brand has direct effects on the brand satisfaction and that the brand satisfaction has direct effects on the brand loyalty were supported. In addition, the findings about whether the perceived value has a significant effect on the brand satisfaction were also acquired. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=brand%20image" title="brand image">brand image</a>, <a href="https://publications.waset.org/abstracts/search?q=brand%20loyalty" title=" brand loyalty"> brand loyalty</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20value" title=" perceived value"> perceived value</a>, <a href="https://publications.waset.org/abstracts/search?q=satisfaction" title=" satisfaction"> satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=trust" title=" trust"> trust</a> </p> <a href="https://publications.waset.org/abstracts/36443/the-analysis-of-the-effect-of-brand-image-on-creating-brand-loyalty-with-the-structural-equation-model-a-research-study-on-the-sports-equipment-brand-users" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36443.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">440</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">5804</span> Research on the Two-Way Sound Absorption Performance of Multilayer Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yang%20Song">Yang Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaojun%20Qiu"> Xiaojun Qiu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multilayer materials are applied to much acoustics area. 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">5803</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.

A curve is fitted to the averaged data and a correlation between the wave power and flow speed is founded. Test data are used to validate the method and errors for all test data were under 10 percent.

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">5796</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.

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">5790</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.

It acts on a subconscious level making them less likely to reject the implicit message delivered by the sound of the brand name. Most of the research conducted in the field was focused on the English language as it is the language used for international branding campaigns and global companies. However, more research is examining the sound symbolism in other languages and comparing it to the English language findings. Besides, researchers have been able to study luxury brand names and spot out the patterns used in them to provoke luxury and sophistication. It stands to a reason to connect the luxury brand names and the local language’s sound effects since a considerable number of these brands are promoting the origin of the Maison, therefore, have names in foreign languages. This study was established around the Hungarian luxury brand names. It aims to spot out the patterns used in these names that connect to the previous findings of luxury sound effects and also the differences. We worked with a non-Hungarian speaking sample who had some basic knowledge of the language just to make sure they were able to correctly pronounce the names. The results have shown both similarities and differences when it comes to perceiving luxury based on the brand name. As the Hungarian language can be qualified as a saturated language, consonant wise, it was easy to feed the luxury feeling only by using designers' names, however, some complicated names were too difficult and repulsive to consider as luxurious. On the other hand, oversimplifying some names did not convey the desired image as it was too simple and easy. Overall, some sounds have been proved to be linked to luxury as the literature suggests, the difficulty of pronunciation has also proved effective since it highlights the distant feeling consumers crave when looking for luxury. These results suggest that sound symbolism can set up an aura of luxury when used properly, leveraging each languages’ convenient assets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hungarian%20language" title="hungarian language">hungarian language</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistics" title=" linguistics"> linguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=luxury%20brands" title=" luxury brands"> luxury brands</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20symbolism" title=" sound symbolism"> sound symbolism</a> </p> <a href="https://publications.waset.org/abstracts/147452/studying-the-linguistics-of-hungarian-luxurious-brands-analysing-the-sound-effects-from-a-non-hungarian-consumers-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147452.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">118</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">5788</span> Implementation of Real-Time Multiple Sound Source Localization and Separation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeng-Shin%20Sheu">Jeng-Shin Sheu</a>, <a href="https://publications.waset.org/abstracts/search?q=Qi-Xun%20Zheng"> Qi-Xun Zheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper mainly discusses a method of separating speech when using a microphone array without knowing the number and direction of sound sources. 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">5787</span> Improvement in Acoustic Performance at Low Frequency via Application of Acoustic Resistance of Vented Hole in In-Ear Earphones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tzu-Hsuan%20Lei">Tzu-Hsuan Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu-Chien%20Wu"> Shu-Chien Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuang-Che%20Lo"> Kuang-Che Lo</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu-Chi%20Liu"> Shu-Chi Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Cheng%20Liu"> Yu-Cheng Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focus of this study was on the effects of air propagation associated with vented holes on acoustic resistance properties. A cylindrical hole with diameter and depth of 0.7 mm and 1.0 mm, respectively, was the research target. By constructing a finite element analytical model of its sound field properties, the acoustic-specific airflow resistance relationships were obtained for the differences in sound pressure and flow velocity at the two ends of this vented hole. In addition, the acoustic properties of this vented hole were included in the in-ear earphone simulation model to complete the sound pressure curve simulation analysis of the in-ear earphone system with a vented hole of corresponding size. Then, the simulation results were compared with actual measurements obtained from the standard system. Based on the results, when the in-ear earphone vented hole simulation model considered the simulated specific airflow resistance values of this cylindrical hole, the overall simulated sound pressure performance was highly consistent with that of measured values. The difference in the first peak values of sound pressure at mid-to-low frequencies was reduced from 5.64% when the simulation model did not consider the specific airflow resistance of the cylindrical hole to 1.18%, and the accuracy of the overall simulation was around 70%. This indicates the importance of the acoustic resistance properties of vented holes. Moreover, as specific airflow resistance values were able to be further quantified, the accuracy of the entire in-ear earphone simulation was ultimately and effectively elevated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=specific%20airflow%20resistance" title="specific airflow resistance">specific airflow resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=vented%20holes" title=" vented holes"> vented holes</a>, <a href="https://publications.waset.org/abstracts/search?q=in-ear%20earphone" title=" in-ear earphone"> in-ear earphone</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a> </p> <a href="https://publications.waset.org/abstracts/186158/improvement-in-acoustic-performance-at-low-frequency-via-application-of-acoustic-resistance-of-vented-hole-in-in-ear-earphones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186158.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">43</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">5786</span> Thermal Insulation, Sound Insulation, and Tensile Properties of Epoxy-Silica Aerogel and Epoxy-Polystyrene Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Ucar">Mehmet Ucar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuray%20Ucar"> Nuray Ucar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Both thermal insulation and sound insulation play a key role in energy saving and the quality of life.
