The Analysis of Factors That Influence the Sound Absorption Coefficient of Porous Materials
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 2
Abstract
In this paper are presented researches on the identification of factors that influence the sound absorption coefficient of porous materials used for absorption of the sound wave. To achieve these researches were used three materials (glass wool, flexible polyurethane foam and rigid polyurethane foam) for which it was determined the sound absorption coefficient using the impedance tube and was analyzed the influence of thickness, density and structure of these materials on the sound absorption coefficient.
