Which Everyday Sounds May Put Your Kid’s Hearing at Risk? [Infographic]
The loudest sound accurately measured by humans was caused by the explosive volcanic eruption of Indonesia’s Krakatoa Island on August 27, 1883.
Krakatoa’s blast registered at 173 decibels 100 miles away from the volcano – which, even at that distance, is substantially above a human’s pain threshold and 30 decibels louder than the immediate vicinity of a firework. Australians more than 2,000 miles away misidentified the volcano’s boom as the round of a shotgun nearby.
This mammoth instance of noise is a rare anomaly. Thanks to metropolitan congestion, however, urban sprawl, and our dependence on noisy machinery, many of us are regularly experiencing situations loud enough to damage our hearing.
Roughly 15% of all US adults and, 16% of teens , have some hearing loss that can be attributed to loud noises. 12.5% of American children have dulled-hearing in one or both ears.
Consistent exposure to everyday noises – subways, sporting tailgates, lawn mowers, traffic, vacuums, even babies crying – can slowly damage our hearing. See how these, and other common sounds, affect your hearing specifically below.
Hearing loss is permanent but preventable.
The mechanics of hearing
Sound waves cause your 1 eardrum to vibrate → this vibration travels through the 2 three small bones of your middle ear → is converted from air vibrations into fluid vibrations within the cochlea → the fluid of your 3 cochlea causes small hair-like projections, called stereocilia, to sway with the vibrations → the swaying of the stereocilia sends signals to the brain which are translated into a noise.
