A B S T R A C T Average sound levels and percentage of daily dose of noise expo- sure were measured in the practice rooms of a university school of music, with the primary objective of determining whether sound levels in student practice rooms were high enough to warrant concern for hearing conservation. A secon- dary objective was to determine whether any instrument group was at higher risk for music-induced hearing loss due to exposure levels. Students represent- ing 4 instrument groups were tested: brass, wind, string and voice. Measure- ments were taken using a dosimeter or DoseBadge clipped to the shoulder dur- ing 40 students' individual practice sessions. These readings provided average exposure levels as well as the percentage of total allowed exposure (dose) ob- tained during the practice session. The mean measurement time for this study was 47 minutes (SD = 22). Mean sound levels measured averaged 87-95 dB(A) (SD = 3.5-5.9). Mean average levels for the brass players were significantly higher than other instrument groups. Using the mean duration of daily practice reported by the participants to estimate dose, 48% would exceed the allowable sound exposure. Implications for professional musicians are discussed, includ- ing the need for 12-hour breaks and the use of musicians' earplugs. The im- plementation of a Hearing Protection Policy in the School of Music will also be discussed.
