Acoustics: Sound Absorption
Brick, stone, concrete, reflect all sound. Timber, gyprock, steel, reflect most high frequencies and a % low frequency is absorbed by the wall. The remaining low frequency energy that is not reflected or absorbed passes through the wall. Nothing can be done about sound that passes through a wall. Bass frequencies are the most difficult to absorb.
How to Soundproof a Room for Music Recording
To prevent sound from entering and exiting a room… The walls of that room require lots of mass…which prevents them from vibrating in response to sound energy. When building a room from scratch, adequate mass can be added to the wall simply by building it thick, with a dense material such as concrete.
Absorbing Vs. Blocking Sound
Because sound that gets through the first layer of gypsum board can be reduced further by absorbing some of its energy before it is able to get through the second layer of gypsum board. The batt insulation is still acting as a sound absorber, not a sound blocker.

Reducing Railway Noise with Porous Sound-Absorbing
The effect of porous sound-absorbing concrete slabs on railway noise reduction is examined in this paper. First, the acoustical absorption coefficients of porous concrete materials with various aggregate types, gradations, fibre contents, and compaction indexes are measured in the laboratory. The laboratory results show that porous concrete that uses a composite of expanded perlite and slag as ...

Engineering Acoustics/Sound Absorbing Structures and Materials
Sound energy is dissipated by simultaneous actions of viscous and thermal mechanisms. Sound absorbers are used to dissipate sound energy and to minimize its reflection. The absorption coefficient is a common quantity used for measuring the sound absorption of a material and is known to be the function of the frequency of the incident wave.
