Measurement of hearing loss in occupational noise-induced hearing loss.
Research on the hearing loss at 2 000 and 4 000 Hz which enabled us to estimate the loss at 3 000 Hz would appear to be the best measure of occupational noise-induced hearing loss: this measure is the most specific and the most discriminating of the suggested formulas. Calculation of the social handicap must take into consideration the same frequencies and the probability of error of identification at the various levels of hearing impairment. Its coefficient is that of the disability in relation to total deafness.
