What Counts as Excessive Noise?
Frightening fact: Hearing loss can occur after a one-time noise exposure at 120 decibels, such as gunfire, or continuous noise exposure to dangerous levels of 85 decibels or above over a prolonged period of time. It's important to know what levels are safe in order to protect your hearing:
Rock concert or jet engine
Home stereo speakers at maximum volume
* Just 1 minute of exposure to noises at this level can result in permanent hearing loss, according to the National Institutes of Health.
* Continual exposure to noises in this range can cause permanent hearing loss.
