Abstract

Abstract

This is a study of the sound attenuation of acoustic shields used in a symphonic orchestra to protect musicians’ hearing. The shields were placed right behind the ears of players who had the highest exposure to the sound of instruments in the pit of the auditorium in the Four Seasons Centre for Performing Arts in Toronto. In order to measure the attenuation of the shield, noise dosimeters were located in front and behind the shields. The field attenuation of each shield was calculated as the difference between the Leq measured on both dosimeters. Two types of shields, Wenger and Manhasset, were measured. The overall attenuation was found to be -0.48 dBA.
