(A) For the purpose of determining decibels (dB(A)) as referenced in this chapter, the noise shall be measured on the “A-weighting scale slow response” on a sound level meter of standard design and quality having characteristics established by the American National Standards Institute.
(B) When the Noise Control Officer determines that insufficient prima facie evidence exists for establishing a noise violation case, the investigating officer will use a sound-level meter to measure the sound level. Sound measurements shall be conducted at that time, day or night, when the suspect noise source is emitting sound.
(C) The following procedures shall be utilized in the sound measurement process.
(1) The sound measurement equipment shall have been calibrated.
(2) Prior to obtaining the sound sample, the sound level meter shall be set to the “A” weighted network at slow response.
(3) No individual other than the operator of the sound meter shall be within ten feet of the sound level meter during the measurement process.
