Abstract: Present study measures effects of impulsive noise level and assesses audiologically occurrence of noise-induced hearing loss or temporary threshold shift (TTS) during gunshot practice by military men. No significant variation in hearing threshold in any frequency before and after gunshot practice was observed, thus no TTS was detected. Alterations in hearing thresholds at 6 kHz and 8 kHz were observed in individuals who already presented cochlear hearing loss. Individuals reported following effects: tinnitus, 21; dizziness, 13; discomfort under loud sounds, 26; and difficulties in speech comprehension, 26%.
