How is sound intensity measured

Web12 okt. 2024 · The closer the particles get or the further apart they get, the greater the sound’s amplitude. Sound amplitude causes a sound’s loudness and intensity. The bigger the amplitude is, the louder and more intense the sound. Sound intensity is measured in Watts per meters squared. How does sound intensity related to the energy of the … 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.
