day-to-day lives, whether consciously or unconsciously, we are continuously exposed to <b>acoustics</b> – the science of sound – through a wide variety of hearing experiences. Our ears are always open and receive not only desirable signals but also undesirable ones in the form of noise. As surveys have shown [1], noise is among the most frequently mentioned types of environmental pollution; it is also known to be detrimental to health. Noise-induced hearing loss is only the most apparent manifestation of this problem [2].</p> <p>Sufficiently accurate reference values and reliable measuring equipment are required to objectively measure and evaluate sound; both prerequisites are fulfilled due to the activities of the acoustics laboratory at METAS.  </p> </div> </div> <div class="multilist " id="id_76410eeee043b1e829e933143d7d9c3e-box"> <h3> Further information </h3> <div class="" id="id_76410eeee043b1e829e933143d7d9c3e-box-content"> <ul class="list-unstyled "> <li class=""> <a href="/dam/metas/de/data/fachbereiche/akustik_vibration/wahrnehmung-von-umweltqualitat-d.pdf.download.pdf/wahrnehmung-von-umweltqualitat-d.pdf" title="[1] Wahrnehmung von Umweltqualität und Umweltverhalten, BFS 2011, Seite 8" class="icon icon--before icon--pdf">[1] Wahrnehmung von Umweltqualität und Umweltverhalten, BFS 2011, Seite 8<span class="text-dimmed"> (PDF, 1 MB, 06.07.2020)</span></a></a> </li> <li class=""> <a href="/dam/metas/en/data/fachbereiche/akustik_vibration/burden_of_deisease_envrionmental_noise_2011-e.pdf.download.pdf/burden_of_deisease_envrionmental_noise_2011-e.pdf" title="[2] Burden of disease from environmental noise.
