Inner Ear - Truth Recordings
... The threshold of hearing is the minimum sound level of a pure tone that an average ear with normal hearing can hear with no other sound present. The reference for 0dB SPL is defined as the ‘threshold of hearing’ of a young undamaged ear in the ears most sensitive range - between 1kHz and 4kHz. ...
