PROBLEM: SOUND OR NOISE TRANSMISSION.
SOLUTION: YOU SHOULD DECOUPLE & STRENGTHEN THE STRUCTURE
Building a soundproof wall to block sound transmission requires materials that are mass loaded, dense and/or resilient. We use these materials in the construction assembly of a wall, floor or ceiling. We can achieve your sound blocking goals by using the materials outlined in this post. Most of these methods will pertain to blocking sound for wall applications, however, we can apply many of the same principles for ceilings and floors.
Inherently, we will need to construct an assembly that contains multiple layers. The layers will be comprised of dense materials and components to separate the structures. The objective is to structurally seal, isolate and decouple the adjacent structures from one another.
Blocking sound requires the complete area to be reinforced or a sealed enclosure around the sound source, as it takes a system of materials to construct a soundproof wall.
