The gap between the wall boards and the decking board is filled with acoustic sealant. The acoustical integrity of a building or a building section with an otherwise adequate stc rating can be significantly reduced by a small hole or crack in the exterior wall or any other path that allows sound to bypass the exterior or interior walls and flow into other areas of the structure. Part e 1 provides protection against sound from separating walls and floors from other parts of the same building and adjoining buildings. Improve the mass of the floor by adding high mass density products a running theme for walls ceilings and floors improve the ability of the floor to absorb sound energy and vibrations footsteps.

Acoustic underlayment special materials that lay over a concrete or plywood subfloor cushioning the flooring and reducing the effects of airborne and impact noise. The wall boards are not in direct contact with the floor decking board or the flooring board. The human ear can discern sounds ranging from approximately 20 hz to 20 000 hz. Building a soundproof wall to block sound transmission requires materials that are mass loaded dense and or resilient.

Reflection the bouncing of sound waves off any hard smooth wall ceiling or floor surface making them audible beyond the immediate area of the source. Acoustic foam is one of them and has much better quality. Part e 2 provides protection against sound internally within a dwelling house for example internal walls between a bedroom or a room containing a water closet and other rooms and internal floors.

Wood has been used as a flooring material for centuries. You can achieve your sound blocking goals by using the materials outlined in this post.

As mentioned previously without this the addition of any mass will have very little effect on impact noise. Likewise sound from below migrates through ceilings to the floor above.
