Sound attenuation building material and system
First Claim
1. A sound attenuating building material, comprising:
- a core matrix disposed on a facing material, the core matrix comprising;
a plurality of cenospheres and perlite; and
a sodium silicate binder adhering together the cenospheres and perlite to form a porous core matrix;
an acoustically transparent material disposed on the exposed face of the building material; and
wherein the acoustically transparent material is a mesh material.

Abstract
A building material configured to enhance sound attenuation and reduction in dB across a walled partition, the building material comprising a facing membrane, a core matrix disposed about the facing membrane, the core matrix comprising a plurality of microparticles and a binder solution configured to support the microparticles, the building material comprising at least a substantially exposed face, wherein a side of the core matrix is at least partially exposed to increase sound attenuation by reducing reflections from sound waves impinging on the building material as compared to a control building material lacking an exposed face. Two building materials may be used in conjunction with one another about a building structure, such as a stud wall, to create and define a sound trap that functions to reduce sound transmission across the partition formed by the stud wall and building materials.
