Convert sound pressure to sound power

WebJun 6, 2013 · (Note for the pernickety... sound pressure is measured in pascals, where one pascal = one newton per square meter. 0 dB SPL is 20 µPa, which clearly is a measurement of sound pressure. This corresponds to 1 pW/m2, which is a measure of sound intensity. It is possible to speak of SIL or sound intensity level, but it isn't common.)
