Field Attenuation Of Individual Orchestra Shields

Alberto Behar, Mohammad Abdoli-Eramasaki, Stephen Mosher

Abstract


A test was conducted to assess the field attenuation of two commercial acoustic shields used by symphonic orchestra musicians. Three different musical instruments, were used as sound sources. The shields were equipped with two noise dosimeters each, located one in front and the other behind the shield. The attenuation was calculated as the difference between the readings of both dosimeters. Attenuations were found to be between 5.8 and 10.7 dBA.
