Multi-Layered products with a heavy layer Sound Insulation

Acoustic Insulation: how to block noise WHAT IS A SOUND OR A NOISE? The sound is composed by longitudinal mechanical waves, characterized by a pressure deviation (+∆pt compression phase, -∆pt rarefaction phase) from an equilibrium point. In case the sound transmits in the air, the equilibrium point is represented by air atmospheric pressure. Like every waves, the sound waves are defined by physical parameters such as frequency, speed, wave length, amplitude. The acoustic pressure is the most distinctive parameter of a sound/noise, basically defining its volume. Unit measure of pressure is...

AIRBORNE SOUND The airborne sound is transmitted through the air. Sound waves propagate firstly in the area/room where they are originated. Then, when the waves reach another surface and/or obstacle (i.e. separation wall), the sound energy is partly reflected and absorbed, and partly transmitted through separation elements. The aim of acoustic insulation system is to decrease as much as possible the transmitted part and, furthermore, avoid too much reflected noise. In building sector, the airborne sound is related to the following situations: • xternal noise, such as façade insulation...
