In modern working environments, occupational noise exposure appears to be diminishing. However, there have been many cases of acute acoustic impairments resulting from leisure noise encountered in civic life. Especially, the possibility of sensorineural hearing loss in connection with rock-and-roll music has been reported. Many patients have long histories of listening to pop music in the past.
Audiograms showed various patterns. It is thought t h at the causes of hearing loss in patients with a dip pattern are mainly due to so-called “delayed recovery NITTS”, and that of low frequency disorder due to acute hearing loss from so-called “short term exposure to noise” (Shapiro).
It is most important that one's own hearing acuity is protected from such sound levels by wearing ear plugs.
