Title Firefighters' hearing: A comparison with population databases from the International Standards Organization
Bibliographic information July 2001, Vol.43, No.7, p.650-656. 19 ref.
Abstract This study investigated firefighters' hearing relative to general population. For five groups of male firefighters with increasing mean ages, their hearing thresholds at the 50th and 90th percentiles were compared with normative and age- and sex-matched hearing data from the standardized ISO and United States population databases (databases A and B, respectively). At the 50th percentile, from a mean age of 28 to a mean age of 53 years, relative to databases A and B, the firefighters lost an excess of 19 to 23dB, 20 to 23dB, and 16 to 19dB at 3000, 4000, and 6000Hz, respectively. At the 90th percentile, from a mean age of 28 to a mean age of 53 years, relative to databases A and B, the firefighters lost an excess of 12 to 20dB, 38 to 44dB, 41 to 45dB, and 22 to 28dB at 2000, 3000, 4000, and 6000Hz, respectively. The results are consistent with accelerated hearing loss in excess of age-expected loss among the firefighters, especially at or above the 90th percentile.
