How is sound intensity measured
WebThe scale for measuring intensity is the decibel scale. The threshold of hearing is assigned a sound level of 0 decibels (abbreviated 0 dB); this sound corresponds to an intensity … WebIntensity. decibel (dB) – a measure of the intensity of a sound; 1/10 of a Bel. Decibels are a relative unit comparing two pressures; therefore, a reference pressure must also be indicated. In underwater acoustics, the reference pressure is 1 microPascal, so the true unit of intensity for underwater sound is dB referenced to 1 microPascal.
