Re: Fixing Acoustics in Basement Practice Area

My advice would be to "shoot the room" with a PC pink noise generator. You
can get them prett cheaply these days

http://www.allworldsoft.com/keywords/pink_noise_generator/ is one example

Next, figure out if you want to alleviate the peaks or do a general dB
reduction. In other words, is say, the 250K buildup responsible for the
noise, or is everything just to loud?

For specific frequency attenuation there are all manner of things - bass
traps, baffles, etc. Go pro on these and save yourself mucho headaches.

For general noise reduction, nothing beats a second wall. Me. I'd build
panels out of 2x4s stuffed with attic insulation and covered in canvas (or
drywall) with a moisture barrier between them and the wall. Then I'd either
drill anchors in the wall, or devise a temporary fastening system like hook
and eye. Maybe some fomcor sheets glued on the bare wall too. But that's
just me.

Begun elsewhere:

Find the place nearest you where they recycle office furniture.
Lots of cubicle dividers are cardboard, but I managed to get about 2
dozen that were 2" thick dense fiberglass. We can revisit the discussion
about why that's the only thing that's going to work in your basement,
if you like. There's no gamble in deadening the sound down there.
There's dense fiberglass, and then there's all the stuff which makes
your room boomy and bass heavy and makes everyone upstairs wonder what
you spent all that money and time on.

===========================

Interesting that you mentioned that idea. Last night during practice, I
was
thinking about building dividers on wheels so I could move them around
easily for vacuuming up the usual strange basement lint that collects on
the
cement floor. But, the office dividers you mentioned are usually no big
deal
to move. I don't want to attach anything to the walls because of moisture
buildup. It's a dry basement, but in the summer, there's a hint of
mustiness
that says "Just a little more and things could get ugly."

Our primary goal is nicer sound for practice, but eventually, we might
want
to record demos and the current environment is totally wrong for that.
It's
an unfinished basement (and always will be).
