Any use established in any district after the effective date hereof shall be so operated as to comply with the following performance standards. No use lawfully established on the effective date hereof shall be so altered or modified as to conflict with these performance standards.

A. Noise: The sound pressure level, to be measured as described below, shall not exceed the following decibel levels in the designated octave bands when adjacent to the designated types of use districts:

Octave Band Cycles Per Second	Residential Districts (R-1, R-2)	Sound Level In Decibels Band
0 to 75	58	73
75 to 150	54	69
150 to 300	50	65
300 to 600	46	61
600 to 1,200	40	55
1,200 to 2,400	33	48
2,400 to 4,800	26	41
Over 4,800	20	35

Objectionable sounds of an intermittent nature which are not easily measured shall be controlled so as not to become a nuisance to adjacent uses.

Method of measurement, as follows: Measurement is to be made at the nearest boundary of the nearest residential area or at any other point along the boundary where the level is higher. The sound levels shall be measured with a sound level meter and associated octave band filter as prescribed by the American Standards Association.

B. Operations, Activities And Storage: All operations, activities and storage (but not off-street parking or loading of motor vehicles in operating condition) shall be conducted or maintained wholly inside buildings, except that storage only may be outside a building if no part of the storage is less than fifty feet (50') from any lot line or line of the tract on which the storage is maintained, and screening, as defined in this title, is provided between such storage and any lot line which abuts a residential district.

C. Lighting: Exterior lighting fixtures shall be shaded wherever necessary to avoid casting direct light upon property located in any residential district or upon any public street or park.
