No store or shop in the center shall use any noisemaking devices, such as phonographs, loudspeakers, amplifiers, radios, television sets or similar devices, so situated as to be heard outside any building in the center; provided, however, that permitted drive-through establishments shall be permitted, as part of any site plan approval, to use such microphones and speakers that are minimally necessary for the functioning of the drive-through operation. In any case where noisemaking devices are proposed, the same shall be permitted only if the developer demonstrates, as part of any site plan application, that such activity will not interfere with the reasonable use of other businesses or other establishments within the development or on adjacent or nearby properties. No smoke, fumes or objectionable odors shall be emitted from any building. The display of merchandise placed on the exterior premises of any building is prohibited.
