Webthey respond (approximately) proportionally to the sound pressure, p. Now the power in a sound wave, all else equal, goes as the square of the pressure. The log of the square of x is just 2 log x, so this introduces a factor of 2 when we convert to decibels for pressures. The difference in sound pressure level between two sounds with p1 and p2 ...
WebThe sound power measurement procedure is guided by the simple user interface of our Dewesoft X data acquisition software. First, you record the background noise while the sound source is off. After that, you turn on the sound source and measure the sound power level of the source. If you use the grouping of the sensor or multiple runs, repeat ...
