Subject: Sound Wall Penetration - Waveguid
I am looking for information on penetrating a sound wall with dielectric
fittings or a waveguide or something of that sort. I have sprinkler
piping passing through a sound wall for a government job, lots of spec's
very little direction, and they want something that will minimize the
sound transfer
