(J) No person shall alter, modify or change any exhaust muffler, intake muffler or other equipment designed to abate noise or any motor equipment unless such alteration, modification or change shall reduce the noise emitted by such equipment. Nothing in this section shall be interpreted to prohibit the replacement of worn noise abatement equipment certified as meeting or exceeding specifications of the manufacturer’s original equipment.
(K) (1) In C-1 Commercial Zoning Districts, at no point on the boundary of a residence district shall the sound pressure level of any individual operation, or the combined operations of any person, firm or corporation, exceed the decibel levels in the designated octave bands shown below for the zoning districts indicated as measured using test equipment per ANSI Standards S1.1-1960, S1.4-1961, S1.11-1966, S1.12-1967, and SAE J-184, and with reference to §§ 9.404 and 9.405 hereof.

(3) For monitoring purposes, the A scale levels (slow response) of 55 dB(A) and 62 dB(A) respectively for residence districts may be used. Any noise levels in excess of these values constitute a violation of this division (K)(3).
(4) Where noise levels below the above-mentioned 55 dB(A) and 62 dB(A) are measured, the octave band test is to be applied in order to determine compliance with this section.
