For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
EMERGENCIES. Essential activities necessary to restore, preserve, protect or save lives or property from imminent danger of loss or harm.
GENERAL PURPOSE SOUND LEVEL METER. A device for measuring sound level in decibel units.
LOCAL AMBIENT. The highest sound level repeating itself during a six-minute period as measured with a general purpose sound level meter, using “A” weighting. The LOCAL AMBIENT shall be determined with the noise source at issue silent, and in the same location as the measurement of the noise level of the source or sources at issue.
NOISE LEVEL. The maximum continuous sound level or repetitive peak level produced by a source or group of sources as measured with a general purpose sound level meter using “A” weighting scale.
PROPERTY PLANE. A vertical plane passing through a property line, which determines the property boundaries in space.
SOUND LEVEL. Expressed in decibels (dB) is a logarithmic indication of the ratio between the acoustic energy present at a given location and the lowest amount of acoustic energy audible to sensitive human ears and weighted by frequency to account for characteristics of human hearing, as given in the American National Standards Institute Standard S1.1, “Acoustic Terminology”, paragraph 2.9 or successor reference. All references to dB in this subchapter utilize the A-level weighting scale, abbreviated dBA, measured as set forth in this section.
VEHICLE. Any device by which any person or property may be propelled, moved or drawn on a highway or street.
