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 psychoacoustically perceived as differing in loudness. The purpose of the phon is to provide a logarithmic measurement (like decibels) for perceived sound magnitude, whi… WebEin Sone entspricht 40 Phon oder 40 dB SPL bei 1000 Hz Sinus.
