How is sound intensity measured
WebSound intensity may be measured in units of energy or work— e.g., microjoules (10 -6 joule) per second per square centimetre—or in units of power, as microwatts (10 -6 watt) per square centimetre. Unlike … WebMeasurement 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 …
