Design Requirements
When sound meets a barrier or wall, three things take place: the sound is transmitted, absorbed or reflected.
Porous materials are usually used to control the absorption and reflection components of sound.
The PDF below provides detailed information on the design requirements for sound reduction, including sound absorption by porous materials, transmission loss - the ability of a material to reduce or resist the transmission of sound, and single number ratings for transmission loss.
