A. Maximum Permissible Sound Levels by Receiving Land Use. No person shall operate or cause to be operated on public or private property and no owner of or tenant upon real property shall allow the operation upon such real property of any source of sound in such a manner as to create a sound level which exceeds the limits set forth in the receiving land use category in Table 4-402 when measured at or within the real property boundary of the receiving land use. Any noise source that produces sound in excess of those levels shall constitute a noise disturbance.
