sound pressure level
sound pressure level
(OP)
Is it possible to measure analytically the sound pressure difference between two end of pipe? if yes how?
((I need to compare with the practically measured one using microphone, FFT - definitely would be T-loss, power difference not the pressure)

RE: sound pressure level
But, want to calculate how much attenuation(sound pressure level difference)can get between ends of pipe using analytical method.
I was wondering if anyway, by using length & dia will help me to caluclate how much attenuate i can get?
(Sound Pressure level = 20 log P/P0, Sound power level - 10 log (W/W0))

Sorry don't know it from the top of my head.
