"This is a new level of acoustic protection"

NOVAhush is a superb way to create a quiet living and working environment. It uses a unique mix of quality polyester. This delivers outstanding acoustic insulation in ceilings and walls.It controls noise transfer from one room to another. Sound energy travels between two rooms through the walls and ceilings by making them vibrate or through any holes there may be.Adding NOVAhush in the cavity of a wall increases the sound insulation of the wall by dissipating some of the energy of the sound wave as it passes through the wall. This dissipated energy cannot be transmitted.

The sound insulation of a wall is the measure of how much sound is transmitted to the other side. The less sound transmitted, the better the sound insulation (regardless of whether the balance of energy is reflected or dissipated).
With NOVAhush used in the wall cavity dissipation of sound in the wall is increased leading to a reduction in the amount of sound energy transmitted.
No change to the sound energy reflected
