re: #24 Amory Blaine

I finally kind of have my practice room set up the way I guess I like, except for the acoustics. I have so many damn reflective surfaces that I can feel the waves bouncing in my head. For some reason voices (people talking) is the worst. I’m going to make a few broadcast absorbers out of owens corning and metal studs and hope that knocks the echo down a bit. Something like this made with corner bead or metal studs.

Acoustics is a fascinating study. Really, what you’re looking for is the frequencies that are the most obvious or annoying to you. The lower the frequency that is kicking your ass, the bigger your panels will need to be (until you get into the bass range, at which point you basically need to redo your walls). You can probably isolate this by using a frequency analyzer and looking for the peaks when playing or speaking. If it’s voices, my guess is going to be somewhere between 250 Hz and 2 kHz; that’s kind of the power band of human voices.
