inexpensive acoustic foam (found some)
Posted: Wed Nov 05, 2014 1:11 pm
I practice in a basement with a fairly low dropped ceiling and some hard surfaces, including a ground level window above/behind my head. My neighbors can't hear me and my wife doesn't care when/how long I practice (call me lucky! 
), but sound reflecting from the ceiling back to my ears has been a bit harsh, which can also be heard on recordings.
I had been looking for a source of inexpensive acoustic foam and found:

I did a few price comparisons (taking panel size, pattern and noise reduction coefficient into account) and the cost is roughly 1/2 that of Aurelex foam for (presumably) the same level of absorption.
I bought a pack of 3" wedged panels (NRC 0.75), covered the window and placed three panels on the ceiling (large, straight "quilting" pins hold them place quite well; took a few minutes to mount) in the tuba bell's line of fire and the difference is amazing. The harshness is gone, sound pressure levels near my ear are reduced a few dB according to my sound level meter and recordings sound much better. If anything, absorption might be a bit too much. I'll have to play around with panel position to get it just right.
These aren't meant to 'soundproof' a room, but they certainly helped tune my practice room's acoustics to my liking for under $100.
