Sound Transmission Class Guidance - HUD

2. ABSORPTION: Sound absorption control is the reduction of sound emanating from a source within a room. The extent of control depends upon the efficiency of the room's surfaces in absorbing rather than reflecting sound waves. A surface, which could theoretically absorb 100% of the sound would have a sound absorption coefficient of 1.0.

How Soundproof Are Concrete Walls? | Soundproof Cow

Apr 06, 2018 · If you have a concrete floor, you may notice that every step produces an audible sound. Impact noises are a byproduct of concrete’s rigidity, which transforms movement into an audible experience. While undesirable, these noisy manifestations can be eliminated with a few soundproofing measures.

Effect of different factors on sound absorption property

For porous concrete with 5 cm and 10 cm thickness, the sound absorption effect is the best value when the porous concrete temperature was at 5 °C. Likewise, with the increase in temperature, the sound absorption effect becomes worse. On the other hand, the best sound absorption effect of 15 cm pavement thickness was at 20 °C. (4)
