Sound Level Measurement To determine whether noise levels are violating city ordinances, city regulators will measure the decibels using a sound level meter. For this reason, testing cannot be done in a sound-contaminated environment. Those regulations, which still stand today, required that all street-legal motorcycles be limited to 83 decibels at that time, with a stricter, 80-decibel limit imposed beginning in 1986, measured with a ride-by test.
