Results: There was a significant reverse correlation between recording of acoustic reflexes with both age and hearing loss average. Loss of hearing sensitivity among seven aged decades was significant statistically. Hear­ing loss showed more decrement in men than women in all audiometric frequencies, and the difference between them was significant in higher frequencies.
