# How Loud is 100 Decibels?

Figuring out how loud 100 decibels is going to sound would best be described by comparing it to sounds around us. Standing as a close as 3 feet, 100 decibels would be as loud as a power mower, motorcycle or chainsaw. You should always wear protective hearing gear when you are going to be exposed to 100 decibels as this could result in hearing loss if you are exposed for a long period of time.
100 Decibels is a decently loud sound. You can compare 100 Decibels to things such as a jackhammer, chainsaw, farm tractor, or an express train. This is loud enough that you would not want to be around it for an extended period of time without ear plugs.
The loudness of 100 decibels is equivalent to the sound of a motorcycle or a snow mobile. At 3 feet away, a power saw rates at about 110 decibels. Sustained exposure to over 95 decibels can result in hearing loss.
