Effective sound insulation in a building depends on the performance of the sound-insulating materials used to stop the transmission of sound through partition assemblies to adjacent spaces.
To create favorable listening conditions within an interior, sound-absorbing materials must be used to reduce the sound level and the reflections generated within the same space. In many cases, sound-absorbing materials also help improve the overall sound insulation of a construction.
Vibration-damping (impact-noise) materials are used to reduce impact sounds produced on the floor above and transmitted through the mass of the floor to the one below.
