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:
Radiation Protection Products manufactures a full line of radiation shielding materials, nuclear shielding and industrial lead products. They include lead lined doors, lead lined drywall (otherwise known as lead lined sheetrock or lead lined gypsum wallboard) and lead lined plywood, leaded x-ray safety glass, leaded glass, lead lined door frames, lead lined view window frames, and many other lead shielding and industrial lead products
