§ 94.22  REGULATIONS FOR DECIBEL MEASUREMENT OF MOTOR DRIVEN VEHICLES ON PUBLIC ROADS.
   (A)   All noise emitted from motor driven vehicles upon public roads shall be measured whenever possible at a distance of at least 50 feet from a noise source located within the public right-of-way.  If measurement at 50 feet is not feasible, measurement may be made at 25 feet and six dB(a) shall be added to the limit provided below.  All such noises in excess of the dB(a) as provided herein shall be prima facie evidence that such noise unreasonably disturbs the comfort, quiet and repose of persons in the area and is therefore in violation of this subchapter.
   (B)   Decibel limitations.
