Phage said:yes you are correct kilowatt, sound pressure doubles every 3db. Sound perception doubles every 10db. The scale is logorithmic so to divide the level by 2 just subtract 3. I just did some quick calculations and found that:
power difference factor = 2^((dB1 - dB2)/3)
the "power difference factor" is how many times more energy dB1 is than dB2
dB1 is the higher dB number
dB2 is the lower dB number
perception difference factor = 2^((dB1 - dB2)/10)
the "perception difference factor" is just how many times louder it sounds
Hope that answers your questions.
