Details
The absolute threshold of hearing (ATH) is the minimum sound level of a pure tone that an average ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism (Durrant & Lovrinic 1984, Gelfand 2004). The absolute threshold is not a discrete point, and is therefore classed as the point at which a response is elicited a specified percentage of the time (Durrant & Lovrinic 1984). The threshold of hearing is generally reported as the RMS sound pressure of 20 Pa (micropascals) = 2Ã 10 5 pascal (Pa). It is approximately the quietest sound a young human with undamaged hearing can detect at 1,000 Hz (Gelfand, 1990). The threshold of hearing is frequency dependent and it has been shown that the ear's sensitivity is best at frequencies between 1 kHz and 5 kHz (Gelfand, 1990).
