dc.description.abstract | This paper presents a theoretical and experimental study that shows the presence of a horizontal asymptote of the absorption coefficient function α(f) in relation with the thickness of the sample. This asymptote conduces to the existence of a critical depth, characterized by a certain attenuation of the sound wave, that limits the absorbing properties of the material. Above this thickness, α(f) does not change noticeably and a progressive increase of the layer thickness only means an unnecessary waste of acoustic material. | en_US |
