Abstract
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. Notre recherche montre que seules les fréquences de 2 000 et 4 000 Hz, approximation de la fréquence 3 000 Hz, sont acceptables pour estimer une perte auditive professionnelle. La moyenne à ces deux fréquences est plus spécifique et plus discriminative. Le calcul de la perte sociale peut se faire à partir de la probabilité d'erreur de la discrimination phonétique, ou ces memes fréquences sont également les plus importantes.
