B. “Ambient” is the composite of noise from all sources near and far. In this context, the ambient noise level constitutes the normal or existing level of environmental noise at a given location.

C. “Construction” means the act or process of building, including but not limited to site preparation, alteration, repair, remodeling, assembly, erection or similar action, of buildings, structures, pavement, flat work and other works including the use of power equipment in connection with activities therewith.

G. “Noise level” means the maximum continuous sound level or repetitive peak level measured using the “A” scale set on “slow.”

H. “Precision sound level meter” means a device for measuring sound pressure level in decibel units according to the American National Standards Institute Type 1 or Type 2 measuring instruments.

I. “Social gathering” means a gathering at a residential unit or other private premises, including but not limited to accessory dwelling units, of ten or more persons who have assembled from different households for social or other community activities.
