The American Speech-Language-Hearing Association states that noises louder than 80 decibels can be potentially dangerous to one’s hearing, depending on the amount of noise and length of time exposed. Sounds from 60 to 80 decibels are considered very loud, while 90 to 110 decibels is considered extremely loud.
An independent motorcycle noise study conducted by measured the decibel levels of four different motorcycle models at 2 feet away from the open end of a muffler at 45 degrees. The average decibel level was 107 decibels at the cruising level and 118 decibels fully revved.
