Pre- and post-exposure audiometry was used to determine hearing threshold at both high and low frequencies. Personal dosemeters and static measurements were made to assess noise levels and frequency characteristics. A questionnaire was used to determine patterns of noise exposure and attitudes to noise levels and hearing loss.

All prehospital personnel were compared to ten in-hospital controls. Results: Our results indicate high-noise exposure levels of ≥80 dB (A) during use of sirens on the MECU and during HEMS operations compared to in-hospital controls (70 dB (A)). We measured an exposure up to ≥90 dB (A) under the helmet for HEMS crew.

Hearing loss can be caused by a myriad of factors—age, noise exposure (occupational or recreational), developmental syndromes, infectious disease, physical trauma, ototoxic drugs and chemicals—all of which are further influenced by genetic …

Abstract. Audiometry and exposure measurements were conducted on workers from fiberglass and metal products manufacturing plants and a mail distribution terminal (N = 313). Workers exposed to noise and styrene had significantly worse pure-tone thresholds at 2, 3, 4, and 6 kHz when compared with noise-exposed or nonexposed workers.

The pure-tone average and the average hearing thresholds at 4 kHz for the groups significantly increased with an increasing noise exposure level. The prevalence of sensorineural hearing loss among the study population is high; and noise exposure is at least contributory. Pre-employment and regular audiometry while on the job is highly recommended.

The baseline audiogram must be preceded by a minimum period of 14 hours of quiet without exposure to workplace noise. The use of hearing protection is an acceptable alternative to the 14-hour quiet period before the baseline audiogram is taken. The baseline audiogram for covered OSHA personnel is defined as follows:

1. “A pre-exam audiometric questionnaire: This is a series of questions to identify conditions that would affect how audiometric testing is conducted, or how results are interpreted. Questions include whether the subject has ear tubes, a current cold or ear problem, or recent loud noise exposure. . . . 2.

Initial or baseline audiometry must be performed when the subject is free from the effects of temporary threshold shift. The subject must be instructed to avoid noise exposure (any environment where they have to shout to be heard) for 24 hours prior to the test. Regular screening audiometry can be performed regardless of noise exposure providing
