Title Temporary changes in hearing after exposure to shooting noise
Bibliographic information 2nd quarter 2004, Vol.17, No.2, p.285-294. Illus. 25 ref.
Abstract The objectives of this study were to evaluate exposure to noise from small-calibre weapons, to compare the post-exposure changes in hearing measured by pure-tone audiometry (PTA) and transient-evoked otoacoustic emissions (TEOAE) and to correlate these changes with noise parameters. The study included 18 hunters (group I) and 28 candidate policemen (group II) exposed to noise from small firearms during target practices. Group I was unprotected during shooting, whereas group II used commonly-available hearing protectors. PTA and TEOAE were performed before and 2-10 min after shooting. Noise exposure was evaluated by in situ measurements. Results show that even short-term exposure to noise from small-calibre firearms might cause temporary hearing impairment. Therefore, the use of earmuffs is strongly recommended, because most of them seem to effectively attenuate noise from small-calibre firearms.
