Abstract: | Noise is ranked among negative factors of our environment. There are different possibilities of noise elimination. Application of suitable sound absorption materials belongs among these possibilities too. The aim of the paper is to investigate sound absorption properties of some porous materials. This work involves the measured frequency dependencies of the sound absorption coefficient. There are many factors that have an influence on sound absorption of the tested porous materials. These factors are evaluated in the conclusion of the work. © European Acoustics Association. | ||||||||||
