CYCLICALLY VARYING NOISE: Any sound that varies in sound level so that the same level is obtained repetitively at reasonably uniform levels of time.
DEVICE: Any mechanism that is intended to produce, or that actually produces, noise when operated or handled.
DYNAMIC BRAKING DEVICE: A device used primarily on a truck for the conversion of the engine from an internal combustion engine to an air compressor for the purpose of braking without the use of wheel brakes, commonly referred to as "jacob's brake" or "jake brake".

PROPERTY BOUNDARY: An imaginary line at the ground surface, and its vertical extension that separates the real property owned by one person from that owned by another person.
SOUND: A temporal and spatial oscillation in pressure, or other physical quantity with interval forces that cause compression or rarefaction of the medium and that propagates at finite speed to distant points.
STATIONARY NOISE SOURCE: Any device, fixed or movable, that is located or used on property other than a public right of way. (Ord. 316-B, 4-6-2011)
