Abstract

MAIA, Juliana Rollo Fernandes  and  RUSSO, Ieda Chaves Pacheco. Study of the hearing of rock and roll musicians. Pró-Fono R. Atual. Cient. [online]. 2008, vol.20, n.1, pp. 49-54. ISSN 0104-5687.  http://dx.doi.org/10.1590/S0104-56872008000100009.

BACKGROUND: rock and roll has as one of its main characteristics the excessive sound pressure levels. Several studies have demonstrated that the sound levels of rock concerts can range from 100 to 115dB (A), with peak levels of 150dB (A). AIM: to study the hearing of rock and roll musicians, analyzing the results of the audiological evaluation and verifying the influence of time of exposure to amplified music. METHOD: a questionnaire was answered by 23 rock and roll musicians (46 ears) who were also evaluated by means of pure tone audiometry, immitance audiometry and transient/distortion product evoked otoacoustic emissions (OAET and OAEPD). RESULTS: regarding the time of exposure to music, values close to the limit of acceptance (tending to be significants) were found in the frequencies of 0.5 and 6kHz, in the pure tone audiometry. A statistically significant difference was also found in the OAET test in the frequency of 2kHz and also in the frequencies of 0.75, 1, 4 and 6kHz in the OAEPD test. CONCLUSION: the results indicate that although hearing loss was not found in the studied population, alteration in the register of the OAE already exists, suggesting alteration of the cochlear function. Regarding time of exposure, the results indicate that musicians with more than 10 years of practice present statistically significant differences when compared to those with less time of exposure.
