Webincreases, the sound absorption coefficient increases too as in table 1. The reason is at low frequency, waves have higher wavelength, which means the thicker material contributed in better absorption [22].The result shows that the thickness influences better sound absorption and is the reason of the high wavelength mentioned [23]. WebAcoustic absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. …

WebA hard material such as concrete is as dissimilar as can be to the air through which the sound moves; subsequently, most of the sound wave is reflected by the walls and little is absorbed. Walls and ceilings of concert halls are made softer materials such as fiberglass and acoustic tiles. WebSound absorption. In addition to the geometric decrease in intensity caused by the inverse square law, a small part of a sound wave is lost to the air or other medium through various physical processes.
