Hello

I’m converting a metal wall shed into a audio room . I’ll be using metal studs to create a room with in a room ,the one issue I have I need to place new stud walls between the original vertical purlins under engineering advice .The stud walls will be semi isolated . The new roof joist won’t be in direct contact the shed structure .

The wall – metal cladding , 35mm air gap ,25mm insulation Dow PIR board , 200mm gap to purlin inner face . The 76mm metal stud wall will be positioned between the purlins .

I will be mounting double fire check dry wall on 1 side or OSB & ply after watching Dennis’s video . looking at using Tecsound SY70 between either board material .

I would like to also add mass to the inside of the stud wall . Would this course a triple leave between the metal cladding and inner lining of the stub wall .

METAL CLADDING – 80MM GAP – DOUBLE WALL CLADDING ,drywall or ply -76MM STUD WALL – DOUBLE CLADDING plywood .

Regards

Mal

Hi Dennis

I have filled out the room analysis . Being a metal clad shed I need to stop as much noise coming out .

I’m looking at 1 cubic meter of activated carbon .

Cheers

M, Carbon is not a noise technology. It is a sound absorption technology. It is used to absorb excess lower frequency energy within your room. A cubic meter will build you 4 BDA units which are only 48 square feet. This is not enough surface area for a small room regardless of usage.
