Résumé

Ci-joint est une étude sur l’atténuation du son par l’entremise d’absorbants acoustiques utilisés pour protéger l’ouïe des musiciens d’un orchestre symphonique. Les absorbants acoustiques furent placés derrière les oreilles des musiciens étant exposés aux niveaux sonores les plus élevés dans la fosse de l’auditorium du « Four Seasons Centre for Performing Arts » à Toronto. Pour mesurer l’atténuation des absorbants acoustiques, des dosimètres furent posés à l’avant et l’arrière des écrans. L’atténuation de chaque absorbant fut déterminé en calculant la différence de Leq des deux dosimètres. Deux types d’absorbants, Wenger et Manhasset, furent mesurés. Le résultat final d’atténuation fut de -0.48 dBA.
