Résumé

Cet article s’intéresse â l’adéquacité de la classification ABC dans l’ACNOR pour l’évaluation des protecteurs auditifs. Le niveau de pression acoustique atteignant l’oreille protégée par douze protecteurs différents (six de classe A et six de classe B) soumis à douze bruits différents est calculé. Les résultats démontrent une dispersion importante des niveaux de pression acoustique ainsi que des chevauchements pour les deux classes de protecteurs, résultent principalement en une "sur-protection". Il est recommandé que le système ABC soit écarté au profit d’un autre système d’évaluation utilisée par la communauté internationale.
