1.8 CF Standard Names: Sound Pressure Level in Air (sound_pressure_level_in_air)

Record Label : sound_pressure_level_in_air

Record Title : Sound Pressure Level in Air

CF Standard Name : sound_pressure_level_in_air

Record Description : 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 air is expressed on a logarithmic scale with reference to a sound pressure of 2e-5 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.
