People’s exposure to noise is steadily increasing, and associated with this, health problems are rising with financial consequences.
For a reduction of the noise, in interior spaces porous sound absorbers are used. These convert the kinetic energy in the air into frictional heat. The absorbers consist mostly of organic materials, which, in event of a fire, present a potential hazard as they release gases that are hazardous to health.
The products currently offered by the clay brick industry for noise control cannot compete with commercial acoustic foams.
The objective of a...
