What does 85 dB sound like?
Motorcycles and lawn mowers usually measure 85 to 90 dB. Normal conversation is measured between 50 and 70 dB. Rock concerts often measure in the 110 to 120 dB range and jet engines taking off and ambulance sirens frequently measure somewhere between 119 and 140 dB. HEI has plans to launch a unique, worldwide hearing conservation workshop in May. HEI is a non-profit organization chartered to advance the science of hearing and improve quality of life by using research and education.
