[QUOTE="Strainger, post: 215463, member: 839"] Vaughan, please note: I'm using a laptop with a microphone that came with my Marantz AV processor - so accuracy is a no-no. But I recorded before and after waterfalls at exactly same settings, so hopefully you can make something of the differences. I measured 30 to 200Hz only for now. Before: [IMG]http://i1174.photobucket.com/albums/r605/Strainger1/waterfallbeforepanel.jpg[/IMG] After: [IMG]http://i1174.photobucket.com/albums/r605/Strainger1/waterfallafterpanel.jpg[/IMG] Interestingly I get a lot of noise between 20 and 30Hz after installing the panels which wasn't there before.
