Pin drop hearing4/27/2024 We know whispering and tiptoeing are soft sounds while lawn mowers, guns and screaming are loud sounds. Only by using protective equipment or by getting away from the noise can additional damage be prevented. This damage is irreversible and causes permanent hearing loss. When loud noises occur, the tiny hair cells located in the inner ear become disfigured, flattened or fused together. The brain interprets the impulses and decides what the sound is and where it's coming from. These bones couple the sound to the inner ear where it is changed into electrical impulses by tiny hair cells connected to the auditory nerve. These vibrations are picked up by three tiny, connected bones located in the middle ear. At the eardrum, sound is changed into vibrations. Sounds are gathered by the outer ear and funneled down the ear canal to the eardrum. How does noise cause hearing loss? Reviewing the basics of how we hear, our auditory system is divided into the outer, middle and inner ear. Before it's too late, protect your hearing and preserve your quality of life so you can continue to enjoy the sounds of nature and music and understand all of the conversation around you. Years of working around loud engines, generators, and aircraft without proper hearing protection permanently damaged my hearing.Įvery day, I see people - flight crews, aircraft maintenance personnel or civil engineering grounds maintenance personnel - making the same mistake I did: not wearing hearing protection or wearing it improperly. You may be unconsciously turning up the TV or radio volume, or blaming other's poor speech for your difficulty in distinguishing between certain consonant pairs that fall in the region where noise-induced hearing loss occurs (for example, D and B, or F and S). The changes are subtle, and you might not even know there's a problem. Once hearing loss from noise occurs, it will never return to normal. When soft and mild, noise is tolerable but when it becomes too loud, it can be annoying and even destroy hearing. Airplanes, cars, trains, lawn mowers, and even radios and television create unwanted sound, which we call noise. Air Force Civil Engineer Support Agency.
