[TheForge] Acoustical baffling

[Chris Worsley]

Putting up one sheet of  t-111 with insulation is not going to do much 
to eliminate the sound your neighbors are hearing. You'll probably have 
to enclose the compressor to really deaden the sound.
I had the same situation with a  portable generator, and a big plywood 
box with ceiling tiles inside worked wonders. Of course, air intake and 
exhaust baffles were part of the construction. Not hard to figure out.
