Lead Sound Proofing / Acoustical Board
Lead sheet serves as the ideal sound barrier (attenuator) because it is both dense and limp. Other acoustical materials in its sound transmission class can be applied in greater thicknesses in an attempt to achieve the same transmission loss, but there is a point at which they gain stiffness that negates the effectiveness of their density.
Advantages of using lead for sound attenuation include:
- High Density
- Pliability
- Easily Adaptable

The stepped line indicates the break between those materials, which are limp enough to use their weight efficiently (below the line) and those, which are stiff enough to lose effectiveness of their weight (above the line).
