Noise exposure and hearing loss was assessed in different instrument groups of a professional balletOrchestra. Those instrument groups experiencing the highest levels of exposure also had the highest pureTone thresholds. Critically, we found that thresholds were not uniform across instrument groups. TheGreatest difference in thresholds was observed at test frequencies above 2000 Hz, peaking at 4000 HzWhere the average difference between groups was as high as 15 dB. The differences could not beAccounted for on the basis of age, years of playing, or years of playing professionally, and are thus mostLikely due to differences in occupational noise exposure. Nonetheless, measured losses for all instrumentGroups did not approach clinically significant levels.Relevance to industry: By combining noise exposure and hearing loss assessment, this study providesInformation that extends current understanding of the occupational risks faced by professional musiciansPlaying in orchestras. This information may be particularly useful in the design and ImplementationOf hearing conservation programs.
