- AMBIENT NOISE LEVEL
- The all-encompassing background noise associated with a given environment without the sound contribution of the specific source in question.
- A standard unit for measuring the sound pressure level. It is equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to a reference pressure which is 20 micropascals denoted as "dB."
- Any occurrence or set of circumstances involving actual or imminent physical trauma or property damage which demands immediate actions.
- EMERGENCY VEHICLE
- A motor vehicle used in response to public calamity or to protect persons or property from imminent danger.
- MOTOR VEHICLE
- As defined in the Motor Vehicle Code of the State of Delaware, or any vehicles which are propelled or drawn by mechanical equipment, such as, but not limited to, passenger cars, trucks, truck-trailers, semitrailers, campers, motorcycles, minibikes, go-carts, snowmobiles, mopeds, amphibious craft on land, dune buggies or racing vehicles.
- Any sound which is unwanted or which causes or tends to cause any adverse physiological or psychological effect on human beings.
- NOISE DISTURBANCE
- Any sound which:
