Peaking over 135dB sounds a little out of line, but then, I wasn't there. OSha regs state that readings be taken on the A scale set at slow response. I took a lot of readings this past winter in practice rooms, and could scare myself with dBa or dBb on fast response. I still got 105dBa slow out of a Yamaha C3 in a small (is there any other kind?) practice room. I gophered OSHA and downloaded 30 pages of rules and regs. If you are into legalspeak it is fascinating, but even if you aren't, the charts for maximum time exposure in varying noise levels can scare if you realise how much time you spend tuning during those "bulk tuning" times. -- Conrad Hoffsommer Ignorance doesn't kill you, but it will Luther College make you sweat a lot.-Haitian proverb hoffsoco@martin.luther.edu
