For the purpose of determining dB(A)'s as referred to in this article, sound levels shall be measured on the A-weighting scale on a sound level meter of standard design and quality having characteristics established by the American National Standards Institute (ANSI) or its successor body.
All measurements shall be taken at or within the nearest residential property line occupied by the complainant, unless otherwise stated. For multifamily structures, including apartments, condominiums, or other residential arrangements where boundary lines cannot readily be determined or do not exist, measurements shall be taken:
(1) from any point abutting the exterior of the complainant's residential unit; or
(2) from any point on the interior of the complainant's residential unit if taking an exterior measurement is impractical or if the noise complained of is emanating from an adjoining unit.
The sound measurement shall be averaged over a period of one minute for purposes of determining the sound level (the "measurement period"). It shall be a violation of this ordinance for the averaged sound measurement to exceed the prescribed dB(A), or for any sound or noise to exceed the prescribed dB(A) level by three or more decibels at any time during the measurement period.
