How to calculate sound pressure

WebTo calculate the rms pressure, there are four steps. First, the pressure of the sound is measured at points along the sound signal. The pressure is then squared each time it is measured. All of these measurements are averaged (added together and divided by the number of measurements). Web4 mrt. 2016 · Sound Pressure Level Calculator.
