[Cob] Soundproofing on a traditionally built wall

[Darin Lang]

the key to soundproofing is isolation.
in traditional building, the options are insulation, double walls so 
that the studs of one do not in any way contact the studs of the other, 
and staggering of studs to keep them a maximum distance apart, then 
filling the space with insulative material to further dampen vibrations. 
The next is a double layer of drywall, with the second layer glued, such 
that there are no screws or nails penetrating the isolation barrier and 
becoming conduits of sound.

For a floor, you would glue strips of wood, fill the space between with 
insulative material then glue another solid floor on top of that. The 
glue and the airspace isolates the two levels.

My thoughts on cob design using those principles, would be to construct 
the home with closets around the exterior forming a double wall shell 
filled with clothes which while not being worn help to keep the house 
warm and quiet.
