Review of the current situation of noise induced hearing impairment, with the opinion that commonly used methods for evaluating hearing impairment and the relationship of such impairment to noise exposure may significantly underestimate the severity of the impairment and overestimate tolerable noise exposure limits. Criteria for acceptable degrees of hearing impairment for speech and a criterion of an acceptable percentage of people to suffer noise induced hearing loss are suggested. A unit of equivalent noise measurement called "speech impairment risk" is proposed for use in setting tolerable limits of exposure to nonimpulsive and impulsive noise with respect to the above criteria or other suitable criteria. The article is followed by papers giving critical comments.
