AbstractQuian et al. performed a noise exposure survey on members of the National Ballet orchestra, using noise dosimeters. A questionnaire was also conducted to gather information on particulars of the surveyed members. Air conducted and bone conducted audiograms were obtained using a clinical audiometer with 5 dB steps. Forty-four of the 52 musicians completed the questionnaire (85%). The majority of respondents reported listening to music through a speaker system (40), while many will also use earbuds with portable listening systems (21). On average the data suggest only a slight to mild mid to high frequency sensory-neural hearing loss in the 4000-6000 Hz region. This is consistent with hearing losses observed in the earlier stages of other forms of noise exposure. for. It is also observed that there are practically no differences between measured and calculated hearing losses at 3000, 4000, and 8000 Hz.
