Acoustical Lead

Lead is an excellent acoustic control solution. It is effective either by itself, fastened to studs as part of the wall or bonded to gypsum board.

Acoustical Control is generally broken into the three functions below:

1. Blocking of sound path by barriers.

2. Damping of structures and surfaces – to reduce vibration and radiation of airborne sound.

3. Absorbing sound - usually by light fibrous materials.
