| Definition | Sound pressure is the difference from the local ambient pressure caused by a sound wave at a particular location and time. Sound pressure level in water is expressed on a logarithmic scale with reference to a sound pressure of 1e-6 Pa. Lp = 20 log10(p/p0) where Lp is the sound pressure level, p is the rms sound pressure and p0 is the reference sound pressure. | ||
