D. General standards. The general standards which may be considered in determining whether a violation of the provisions of this section exists shall include, but not be limited to, the following:
(2) Whether the nature of the noise is usual for a residential area or unusual;
(3) Whether the origin of the noise is natural or man-made;
(4) The level and intensity of the background noise, if any;
(5) The proximity of the noise to residential sleeping facilities;
(6) The nature and zoning of the area within which the noise emanates;
(7) The time of the day and night the noise occurs;
(8) The duration of the noise;
(9) Whether the noise is recurrent, intermittent, or consistent; and
(10) The effects on public health, safety, property values, and general welfare.
E. Specific standards.
(1) Notwithstanding the general standards and any other provisions of this section, and in addition to and in implementation of the general standards, the following specific standards shall be applicable:
(a) Average outdoor A-weighted sound levels shall not exceed 55 dBA during daytime hours and 50 dBA during nighttime hours. Such average sound levels shall be calculated as a continuous stream of one-minute moving averages. Each point used in the comparison shall be determined as the arithmetic average of all instantaneous readings occurring within the prior one-minute time window.
(b) Impulsive A-weighted sound levels shall not exceed 145 dB on one occasion in a twenty-four-hour period, 135 dB on 10 occasions in a twenty-four-hour period, and 125 dB on 100 occasions in a twenty-four-hour period.
(2) Sound levels of noise radiating from a property line at a distance of 25 feet or more therefrom in excess of the dB established for the stated time periods shall constitute prima facie evidence that such noise is a public nuisance.
F. Approval of plans. No plans for construction of new facilities or for expansion of existing facilities will be approved unless such plans include all control measures necessary to ensure that the proposed daytime and nighttime average sound levels do not exceed the specific standards and are consistent with the general standards and best management practices have been utilized for the mitigation of noise disturbances.
G. Absorptive sound barriers. The use of absorptive sound barriers will be consistent with the general standards and will satisfy the specific standards if they are properly placed within the right-of-way of the proposed road or the expansion of the existing road and are of sufficient height, thickness and length to be consistent with the maximum sound levels permitted herein on the residential side of the barriers.
H. Interpretation of provisions. In interpreting and applying the provisions of this section, they shall be held to be the minimum requirements for the promotion of the public health, safety, quality of life, preservation of property values, and general welfare of the residents of the Township and historical, recreational, and natural features and resources located within the Township. When the provisions of this section impose greater restrictions or requirements than those of any statute, other ordinance, section or regulation, the provisions of this section shall control. When the provisions of any statute, other ordinance, section or regulation impose greater restrictions or requirements, the provisions of such statute, other ordinance, section or regulation shall control. The adoption of this section shall not affect, amend or alter any other ordinances or regulations of the Township, which are hereby expressly saved from repeal. In the event of conflict between these standards and standards established by any other governmental agency, the more restrictive standards will apply in order to achieve the maximum reduction of noise disturbances.
