In response to a request from the International Association of Fire Fighters (IAFF) audiometric examination and pulmonary function testing were performed for 800 participants at the Ninth Redmond Symposium in Anaheim, California. Of the 800 participants, 375 filled out the self administered questionnaire during the five days of the symposium. The 333 who were included in the data analysis ranged in age from 20 to 65 years, with a mean age of 29 years. The results indicated that the participating fire fighters had high frequency hearing losses that progressively got worse as the years of service of the fire fighter increased. The left ears had poorer hearing than the right ears. These hearing losses were statistically related to aging. Presbycusis was characterized by high frequency losses which progressively got worse at higher frequencies. Even though this study did not document an occupational etiology to the hearing loss experienced by half of these participants, the study was limited by the self selection of participants and the audiograms were generally more suggestive of noise induced hearing loss than presbycusis.
