B.  "dBA" means the sound pressure level in decibels measured using the "A" weighting network on a sound level meter. The sound pressure level, in decibels, of a sound is twenty times the logarithm to the base ten of the ratio of the pressure of the sound to a reference pressure of twenty micropascals.

C.  "EDNA" means the environmental designation for noise abatement, being an area or zone (environment) within which maximum permissible noise levels are established.

O.  "Receiving property" means real property within which the maximum permissible noise levels specified in this chapter shall not be exceeded from sources outside such property.

P.  "Sound level meter" means a device which measures sound pressure levels and conforms to Type 1 or Type.2 as specified in the American National Standards Institute Specification §1.4-1971. (Prior code §8.28.010).

8.20.020 Vehicle noise.
