The temperature hit the 80's here in Greenville, and over 20 people showed up at the Sunshine Shop on Saturday for the group ride. Today the heat continues. When I lived in upstate New York, cycling days were precious, particularly in the Spring. Old habits die hard, so any time the weather is good, I hit the road. I thought it would never happen, but some days I want rain.
In between rides I played around more with the AcoustiSoft program, found some mistakes with the way I was interpreting results, and made an important decision.
No matter how many traps and acoustic panels I used, there was an overwhelming 58-62 cycle resonance . I played a test signal in this frequency and I could feel the foil side of the traps vibrating! The vibration was very strong along the floor edges right where I had set up the recording booth. Two problems with this for playing and recording a 12-string are, one, the lowest string is tuned mighty close to this resonance for a couple of my twelve-strings. Two, the radon fan vibrates in this area, and I don't want to keep turning it off and then forgetting to turn it back on. So I abandoned the idea of having a booth near the wall and ran some tests in front of the listening position. As far as I can tell, everything looks better. Time to see if it sounds better.
