   (A)   General. No person shall make or cause to be made any distinctly and loudly audible noise that unreasonably annoys, disturbs, injures, or endangers the comfort, repose, health, peace, safety, or welfare of any persons or precludes their enjoyment of property or affects their property’s value. This general prohibition is not limited by the specific restrictions of the following subdivisions.
   (B)   Motor vehicles. No person shall operate a motor vehicle in the city in violation of the motor vehicle noise limits of the Minnesota Pollution Control Agency.
   (C)   Horns, audible signaling devices, and the like. No person shall sound any signaling device on any vehicle except as a warning of danger, as required by M.S. § 169.68, as it may be amended from time to time.
   (D)   Exhaust. No person shall discharge the exhaust, or permit the discharge of the exhaust of any steam engine, stationary internal combustion engine, motor boat, motor vehicle, or snowmobile except through a muffler or other device that effectively prevents loud or explosive noises therefrom and complies with all applicable state laws and regulations.
   (E)   Defective vehicles or loads. No person shall use any vehicle so out of repair or so loaded as to create loud unnecessary grating, grinding, rattling, or other noise.
   (F)   Loading, unloading, unpacking. No person shall create loud and excessive noise in loading, unloading, or unpacking any vehicle.
   (G)   Radios, phonographs, paging systems, and the like. No person shall use or operate or permit the use or operation of any radio receiving set, musical instrument, phonograph, paging system, machine or other device for the production or reproduction of sound in a distinctly and loudly audible manner as to unreasonably disturb the peace, quiet and comfort of any person nearby. Operation of any such set, instrument, phonograph, machine or other device between the hours of 10:00 p.m. and 7:00 a.m. in such a manner as to be plainly audible at the property line of the stricture or building in which it is located, in the hallway or apartment adjacent, or at a distance of 50 feet if the source is located outside a structure or building shall be prima facie evidence of a violation of this section.
   (H)   Participation in noisy parties or gatherings. No person shall participate to any party or other gathering of people giving rise to noise, unreasonably disturbing the peace, quiet, or repose of another person. When a police officer determines that a gathering is creating such a noise disturbance, the officer may order all persons present, other than the owner or tenant of the premises where the disturbance is occurring, to disperse immediately. No person shall refuse to leave after being ordered by a police officer to do so. Every owner or tenant of the premises who has knowledge of the disturbance shall make every reasonable effort to see that the disturbance is stopped.
   (I)   Loudspeakers, amplifiers for advertising, and the like. No person shall operate or permit the use or operation of any loudspeaker, sound amplifier, or other device for the production or reproduction of sound on a street or other public place for the purpose of commercial advertising or attracting the attention of the public to any commercial establishment or vehicle.
   (J)   Schools, churches, hospitals, and the like. No person shall create any excessive noise on a street, alley, or public grounds adjacent to any schools, institution of learning, church, or hospital when the noise unreasonably interferes with the working of the institution or disturbs or unduly annoys its occupants or residents and when conspicuous signs indicate the presence of the institution.
