So you don’t go to any loud concerts, you don’t work around heavy machinery without proper ear protection, and you always keep your tv and music at a reasonable volume — can you still lose your hearing from the everyday sounds around you?
ASHA provides a breakdown of sound decibel levels. Though the effect of day to day noise on your hearing is dependent not only on sound level but also on the length of exposure to that sound, some items you might not think twice about can have a noticeable effect on your hearing. An average blow dryer, kitchen blender, or food processor can be measured between 80 – 90 dBA (decibels), and the National Institute for Occupational Safety and Healthy (NIOSH) recommends anyone exposed to noises “85 dBA or louder for more than 8 hours a day” should make efforts to limit their exposure at that level.
A blow-dryer, of course, is not a jet engine, but if you’re exposed to it’s noise level for a long enough time, the effects on your hearing can be comparable.
The National Institute on Deafness and Other Communication Disorder (NIDCD) rates anything above 85 dBA as the level – after 8 hours – at which hearing damage begins to occur. Anything below 85 dB (washing machines, city traffic, vacuum cleaner, normal conversation) is considered safe and exposure for up to 24 hours will not cause any hearing loss.
Pretty self explanatory, though there are still some sounds louder than you might realize.
1.) Driving in a convertible – 85 – 91 db at 55 mph or more.
2.) Electric drill / consumer power tools. Many tools won’t reach over 90 dBa, but some might sneak up to ~115, which means safe level of exposure is dropped from 2 hours to 15 minutes. When using tools, always play it safe and wear ear protection.
3.) Noisy restaurants. They’re not quite on the level of a club or concert, but restaurants can be unexpectedly noisy. According to Noisy Planet, restaurant “reviewers have noted noise level averages of 80 decibels or higher in restaurants around the country.”
For a safety regarding length of exposure, be sure to check out our past blog on sound and decibel levels.
Most sounds you hear day in and day out won’t harm your hearing, and you don’t have to go around carrying a decibel meter or anything (though there are handy measuring apps you can get on your phone). Just remember to wear ear protection while using tools, and avoid any prolonged sound that makes you uncomfortable.
