(A) General provision; tests for noise disturbances. In addition to the plainly audible standard, the following factors shall be considered in determining whether a civil violation exists:
(1) The nature and zoning of the area within which the noise emanates;
(2) The time of the day or night the noise occurs;
(3) The duration of the noise; and
(4) Whether the noise is recurrent, intermittent or constant.
(B) Classification of use districts. It is unlawful to project a sound or noise, from one property into another, within the boundary of a use district which exceeds the maximum permissible sound levels set forth in Table 1 below.
(1) Sound or noise projecting from one use district into another use district with a different noise level limit shall not exceed the limits of each district into which the noise is projected.
(2) Measurements shall conform to standardized practices and must be completely delineated in any submitted noise report. Measurements shall be taken to present an accurate representation of the sound. The following conditions must always be met when applicable testing is underway:
(a) The measurement of sound shall be made with a sound level analyzer and shall conform to ANSI 1.4-1983. Either Type 1 or Type 2 sound analyzers are permitted per ANSI S1.4-1971. If octave band testing is required, octave band or one-third octave band analyzers filter sets shall conform to ANSI 1.11-1976.
(b) Calibration of all instruments, components, and attachments shall conform to the latest ANSI standards.
(c) The measurement shall be made at or within the property line of the receiving land use as specified in Table 1.
