Abstract: | Objectives An investigation of the hearing status of musicians of professional symphony orchestras. Main questions are: (1) Should musicians
be treated as a special group with regard to hearing, noise, and noise related hearing problems (2) Do patterns of hearing
damage differ for different instrument types (3) Do OAE have an added value in the diagnosis of noise induced hearing loss
(NIHL) in musicians.
Methods 241 professional musicians, aged between 23–64 participated. A brief medical history and the subjective judgment of their
hearing and hearing problems were assessed. Musicians were subjected to an extensive audiological test battery, which contained
testing of audiometric thresholds, loudness perception, diplacusis, tinnitus, speech perception in noise, and otoacoustic
emissions.
Results Most musicians could be categorized as normal hearing, but their audiograms show notches at 6 kHz, a frequency that is associated
with NIHL. Musicians often complained about tinnitus and hyperacusis, while diplacusis was generally not reported as a problem.
Tinnitus was most often localized utmost left and this could not be related to the instrument. It was usually perceived in
high frequency areas, associated with NIHL. In general, musicians scored very well on the speech-in-noise test. The results
of the loudness perception test were within normal limits. Otoacoustic emissions were more intense with better pure-tone thresholds,
but due to large individual differences it can still not be used as an objective test for early detection of NIHL.
Conclusions Musicians show more noise induced hearing loss than could be expected on the basis of age and gender. Other indicators, such
as complaints and prevalence of tinnitus, complaints about hyperacusis and prevalence of diplacusis suggest that musicians’
ears are at risk. Continuing education about the risks of intensive sound exposure to musicians, with the emphasis on the
possible development of tinnitus and hyperacusis and the need for good hearing protection is warranted. |
