      (1)   No person operating or occupying a motor vehicle within the City shall operate or amplify the sound produced by a radio, tape player, CD player, or other sound making device or instrument from within, or on, said motor vehicle so that the sound is:
         A.   Audible at a distance of 100 feet or more from the motor vehicle; or
         B.   Louder than necessary for the convenient hearing by persons inside the motor vehicle in areas adjoining churches, schools or hospitals.
      (2)   The provisions of this section shall not apply to any law enforcement motor vehicle equipped with any communication device necessary in the performance of law enforcement duties or to any emergency vehicle or public safety vehicle equipped with any communication device necessary in the performance of any emergency procedures.
      (3)   The provisions of this section shall not apply to motor vehicles used for business or political purposes, which in the normal course of conducting such business, use sound making devices.
      (4)   The provisions of this section shall not apply to the noise made by a horn or other warning device required or permitted by state law.
      (5)   As used in this section, "audible" shall mean any sound produced by a radio, tape player, CD player, or other mechanical or electronic sound making device or instrument, from within the interior or on the exterior of a motor vehicle, including sound produced by a portable sound making device, that can be heard outside the vehicle by a person using his normal hearing faculties at a distance of 100 feet or more from the motor vehicle.
      (6)   A law enforcement officer who hears a sound that is audible, as defined herein, shall measure the sound according to the following standards:
