Soundproofing a Band rehearsal space room
« on: June 22, 2005, 02:17:09 PM »
  I am a contractor, in a band, and just in the final stages of soundproofing a rehearsal room in the basement of my duplex house.

My plan is to fill the wall and ceiling cavities with 'Fill-a-foam' (I was going to use a cellulose 'blown- in' insulation but it would not stick in the ceiling with out first closing the ceiling and I was not comfortable with not being able to see that the entire cavity would be filled) then I will use two layers of 5/8" sheetrock or du-rock (concrete tile backer) then MLV, then resilient channel (no sound-clips) then a single (or double layer, depending on the results) of 5/8" drywall cut a 1/4" short from the ceilings, walls and floor, that joint would then be filled with either a silicone or latex caulk.

Do you think it is absolutely necessary to spend the money on the sound-clips? And do you think sheetrock is as good at blocking sound transmission as concrete-board?

My band is loud and has lots of low-end bass signals, the room is not that big (about 12'x12') do think I'm on the right track?

Thank you in advance for your input.

Hello Simon,

How did the "fill a foam" work out.  Did it multiply or reduce sound transfer?  A better choice in the future would be bonded cotton rolled insulation (3 1/2" & 5" thick available). As for sheetrock vs du-rock - the durock is better at blocking sound (more mass).  RC-2 (resilient channel for ceilings) does not carry nearly the weight of sound clips with DWFC.  It is rated to carry 2 layers of drywall so you should be OK.  Fill perimeter 1/4" gap with acoustic caulk only - not silicone or cheap latex caulk.  Low-end bass is handled by large dead-air space
and/or closed cell vinyl nitrile foam (one of the few materials that has STC AND NRC) within an enclosed air space.
