We installed Sonex in a small room that contained an MS, HPLC, N-terminal
sequencer and a noisy exhaust fan. Our maintenance guys who stuck it to the
walls and ceiling could detect no decrease in the noise level using a dB
meter...however I subjectively noticed that I did not have to talk as loud and
I could hear others talking easier than before...so expect only a subtle
difference...in our case we had "hard" ceilings and walls so as previously
mentioned the Sonex probably cut down on echoes or maybe certain
frequencies...based on our experience I would suggest giving it a try but don't
expect to hear babbling brooks and meadowlarks!!

Patrick,

I coated a wall behind a large and whiny MALDI/TOF with "SONEX classic"
panels. I found the stuff on the web. Here is a picture:

and the address I got it from:

SILENT SOURCE - 58 Nonotuck Street, Northampton, MA 01060
phone/fax: (413) 584-7944 order line: (800) 583-7174

It works. I'm now putting it behind everything in the lab including
whiny hard drives. It passes Hospital fire regs and I just use push pins
along the top edge to install.

hope this helps, Paul

ps. And if any DNA Sequencers have read this far and not submitted data,
get off your butt. Fun fact: Dominatrix appears on 11,328 web sites.
