[Prevention of noise induced hearing loss in musicians of Chinese opera].
The incidence of hearing impairment in musicians of Chinese opera is higher than that in popular music and rock and roll music. The sound levels of different instruments used in Chinese opera measured acoustically showed drums, gongs and cymbols to be hazardous to the ear. The conventional measures of prevention, such as ear plugs are not acceptable by the musicians because of interference to the musician's hearing ability. A rearrangement of situations of the musicians was suggested by the authors. The percussive musicians should be situated one meter lower than other musicians. Animal (guinea pigs) experiments by study of AP in EcochG and ultrastructural observations of the cochlea have confirmed that our suggestion for prevention of noise induced hearing impairment to be efficient.
