Hi Everyone,
Thought I would post a follow up to my last post. I have done more research,
and here is what I found. Many people seem to recommend the following
approach:
1. Apply mass-loaded-vinyl (1lb/sq ft) to walls - either directly (if it has
the foam backing) or on top of firring.
2. If 1 above is sufficient, apply sheetrock using standard construction. If
not, build resilient channel on top of MLV and apply sheet rock.
I have a drop ceiling, so I could apply the MLV easily enough. The floor
also has ceramic tiles (as does the adjacent control room...) which of
course are problematic. I would apply MLV there too.
In each case, none of the added construction will touch existing walls,
floor or ceiling. Acoustical caulk would be used to fill in gaps and
perimeter.
I have also read about QuietRock. But I have found no pricing info which is
scary. They claim MLV actually only adds about 3-4dB to the STC. In any
case, the MLV generally goes for around $200 for a 4.5' x 30' roll (closer
to $300 for the stuff with foam backing).
What do you think?
Out of curiosity, what SPL would you expect to be coming out of a guitar cab
for recording purposes (measured a foot away)? I am trying to get a feel for
how loud people crank amps in a studio.
thanks,
brian
