Phon in db
The phon is a logarithmic unit of loudness level for tones and complex sounds. Loudness is measured in sone which is a linear unit. Human sensitivity to sound is variable across different frequencies; therefore, although two different tones may present an identical sound pressure to a human ear, they may be … See more By definition, the loudness level in phons of a sound is the sound pressure level (in dB SPL) of a 1-kHz pure tone that is judged as having the same loudness. The phon unit is not an SI unit in metrology.

The loudness level of a sound is a subjective, rather than an objective, measure. To measure loudness, the volume of a 1,000-hertz reference tone is adjusted until it is perceived by listeners to be equally as loud as the sound being measured. The loudness level, in phons, of the measured sound is then equal to the sound-pressure …
