Jon,This is just some helpful advice on how the log scale works. A factor of 1% is not -40 dB, but is actually -20 dB (since it represents 1/100th).
A factor of 10 times, or 1/10th, is 10 dB. A factor of 100 times, or 1/100th, is 20 dB (10 dB plus 10 dB). A factor of 1000 times, or 1/1000th, is 30 dB (10 dB plus 10 dB plus 10 dB). A factor of 10,000 times, or 1/10,000th, is 40 dB (four times 10 dB).
An easy way to do this on your scientific calculator is:
10 X log(# times) = # dB
Kind Regards, Chris
