We use decibels (dB) when we describe sound levels. Noise is considered too loud and potentially damaging when it exceeds 85 dB. Normal speech is 55 dB, a chainsaw is 95 dB, and a handgun blast can be as much as 160 dB. As a general rule, if you have to raise your voice over the noise, you should be wearing hearing protection. Levels over 120 dB can cause permanent damage even after one brief exposure. Avoid loud noise and when that is not possible, wear ear protection. If you suspect hearing loss, consult your hearing professional.
