The Relationship Between Exposure to Recreational Noise and Temporary Threshold Shifts in Women.
Shirreffs, Janet; And Others
An investigation was conducted to identify the effects of exposure to selected entertainment environments on hearing threshold levels. Twenty-five normal hearing females were randomly assigned to one of the following five taped noise conditions: (1) a discotheque band, (2) a motor speedway, (3) a hotel dance band, (4) an amusement park, and (5) a control recording of low-level exposure. Pure-tone air conduction threshold levels were measured binaurally at 12 frequencies in three trials prior to exposure, 2 minutes after exposure, and 30 minutes after exposure. Temporary threshold shifts and recovery patterns of the five exposure conditions were compared by analysis of variance with repeated measures. The main effects of frequency and trials were significant (p less than .05). The findings indicated that exposure to selected entertainment noise created significant temporary hearing losses at certain frequencies; no losses were observed, however, which met damage-risk criteria.
