A Comparison of Two Different Sound Intensity Methods to Measure the Sound Power Level 2008-36-0235
Measurement of sound intensity involves determining the sound pressure and the particle velocity at the same position simultaneously. The p-p method for measuring intensity uses two pressure microphones that determine the particle velocity component in the direction of the axis of the probe by a finite-difference approximation to the pressure gradient in Euler's equation of motion, and the sound pressure is simply the average of the two pressure signals. The p-u method uses a sound intensity probe that combines an acoustic particle velocity transducer with a pressure microphone (p-u probe). These two sound intensity methods could be used to measure the sound power level of sources.
