Ear Protection in Minnesota
Who Needs Hearing Protection?
If you’re exposed to 85 decibels (or louder) of noise over an 8 hour time period, you really need to wear hearing protection. If you stop and think about it, that’s not that loud. Lawn mowers are about 90 decibels, and a bulldozer, even when idling, makes enough noise to harm your hearing in just one day of construction work.
