How Loud Is Too Loud?
Noise-induced hearing loss is caused by a combination of volume and duration. Damage starts to occur after 85 decibels, and for every three-decibel increase, the amount of time you can be safely exposed (without earplugs) decreases by half. Keep in mind that the time limit is your total for the entire day; any more within a 24-hour period can do harm.
