te How Fire Arms affect our hearing ability Fire arms affect our hearing ability negatively due to the loud noise they produced when fired. These results to what we refer to as noise- induced hearing loss. It is induced by sounds that are too loud or loud sounds that often last too long. Some very sensitive structures such as the hair cells are small sensory cells that convert the sound waves to electrical signals that travel, through the auditory nerve, to the brain. Once these hair cells are damaged they cannot grow back (Kale 1992).
