One-way sound insulation

Illustration of how installations in the void can give rise to noise.Installations in the void between the structural soffit and the suspended ceiling, such as piping and ductwork systems, can give rise to noise.

In such cases, a sound insulating suspended ceiling system can be used to reduce the noise to acceptable levels in the room below.
