Temporary threshold shift after exposure to pop music. 1978

A Axelsson, and F Lindgren

Temporary threshold shift (TTS) was studied in pop musicians as well as in listeners. It appears that TTS is less pronounced in pop musicians than in listeners. This can only in part be explained by slightly inferior hearing threshold levels than in the audience before exposure. Further, male listeners showed more TTS than female listeners. After 2 hours of exposure to live pop music a TTS2 appears in pop musicians after an exposure to 98 dB(A) as opposed to listeners where TTS2 appears at 92 dB(A). When the present results are related to the CHABA risk criteria it seems that exposure to live pop music at 100 dB(A) for 2 hours is a limit which should not be exceeded if the risk of permanent hearing loss is to be avoided.

D000162	Acoustics	The branch of physics that deals with sound and sound waves. In medicine it is often applied in procedures in speech and hearing studies. With regard to the environment, it refers to the characteristics of a room, auditorium, theatre, building, etc. that determines the audibility or fidelity of sounds in it.

D001305	Auditory Fatigue	Loss of sensitivity to sounds as a result of auditory stimulation, manifesting as a temporary shift in auditory threshold. The temporary threshold shift, TTS, is expressed in decibels.	Fatigue, Auditory,Temporary Threshold Shift, Auditory,Auditory Fatigues,Fatigues, Auditory
