The operation of any such set, instrument, phonograph, machine or device between the hours of 11:00 p.m. and 7:00 a.m. in such a manner as to be plainly audible at a distance of 50 feet from the building, structure or vehicle in which it is located prima facie evidence of a violation of this section;

For the purpose of this subsection 2.c., the term EXCESSIVE NOISE shall mean noise or sound which unduly disturbs injures or endangers the comfort, repose, peace, safety or health of any person.
