Abstract(s)
For musicians, the impact of noise exposure is not yet fully characterized. Some inconsistencies can be found in the
methodology used to evaluate noise exposure. This study aims to analyze the noise exposure of musicians in a symphonic
orchestra to understand their risk for hearing loss, applying the methodology proposed by ISO 9612:2009. Noise levels
were monitored among musicians during the rehearsal of eight different repertoires. Test subjects were selected according
to their instrument and position in the orchestra. Participants wore noise dosimeters throughout the rehearsals. A sound
meter was used to analyze the exposure of the conductor. The results showed that musicians are exposed to high noise
levels that can damage hearing. Brass, woodwind and percussion and timpani musicians were exposed to noise levels
in excess of the upper exposure action level of 85 dB (A), while the other instrumental groups had a lower exposure
action level of 80 dB (A). Percussion musicians were exposed to high peak noise levels of 135 dB (C). Sound levels
varied by instrument, repertoire and position. Octave frequency analyses showed differences among musicians. This
study suggests that musicians are at risk for hearing loss. There is a need for more effective guidelines applicable to
all countries, which should define standardized procedures for determining musician noise exposure and should allow
exposure level normalization to the year, including different repertoires.
