Not exactly - 36 dB doesn't translate to 36 orders of magnitude (10^36). In sound, 3 dB is a doubling of sound levels, so it's 2^12 times louder (or quieter). Also note that SPL (Sound Pressure Level), measured in deciBels, weighted toward human ear response ("A" weighting, or dBA) is
subjective, in that 1 dB is defined as the smallest change that a human can detect. Yes, it is
measured objectively, but the delta SPL is subjective for 1 dB.
Nonetheless, I wear ear plugs at every FIRST event, even in the pits, with few exceptions - it seems to me like it is
always too loud, and I like my hearing thank you.
