Résumé

Le risque de perdre l’ouïe à cause de bruits excessifs, lorsque qu’un protecteur auditif est utilisé, ne peut être que calculé en connaissant le niveau de bruit à l’oreille protégée. Plusieurs méthodes sont disponibles pour effectuer ce calcul en utilisant les données de l’atténuation du bruit du protecteur auditif. Toutefois, les données disponibles sont obtenues grâce à des méthodes fort éloignées des situations que l’on retrouve dans la réalité de l’environnement de travail. C’est pour cette raison que les résultats sont erronés. Cet article revoit les méthodes existantes pour les calculs des mesures d’atténuation et du niveau du bruit. Il suggère aussi différentes façons pour éviter l’utilisation de données inexactes d’atténuation du bruit.
