Human hearing spans seven orders of magnitude in sound pressure

Evidence

In psychoacoustics, values of the sound pressure between 10-5 Pa (absolute threshold) and 102 Pa (threshold of pain) are relevant. In order to cope with such a broad range of sound pressures, the sound pressure level, L, is normally used. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
