Studies on the prevention of noise-induced hearing loss among musicians of traditional Chinese opera
【摘要】：正 The incidence of hearing impairment in musicians of traditional Chinese opera is higher than that in popular music and rock and roll music. The sound levels of different instruments used in traditional 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 acuity. A rearrangement of the seats for the musicians was suggested by the authors, the percussive musicians should seat themselves one meter lower than the other musicians. Animal (guinea pigs) experiments by study of AP in EcochG and ul-trastructural observations of the cochlea have confirmed that our suggestion for prevention of noise -induced hearing impairment to be efficient.
