WebThe threshold of hearing is generally reported in reference to the RMS sound pressure of 20 micropascals, i.e. 0 dB SPL, corresponding to a sound intensity of 0.98 pW/m 2 at 1 atmosphere and 25 °C. It is approximately the quietest sound a young human with undamaged hearing can detect at 1,000 Hz. WebWhen we’re talking about the loudness of a sound, the human hearing range is between 0 dB and 140 dB. 0 dB is the human hearing threshold, while 120-140 dB is the threshold …

WebNormal hearing range is from 0 dBHL (Decibel Hearing Level), which is the audiometric zero, to 20 dBHL. Any threshold, at any frequency, that is over 20 dBHL is identified as hearing loss. Though a ‘normal’ audible range for loudness is 0 – 180dB, anything over 85dB is considered damaging for our hearing. Typically, the younger we are ... WebOn the decibel scale, the range of human hearing extends from 0 dB, which represents a level that is all but inaudible, to about 130 dB, the level at which sound becomes painful. …
