Summary
In the City of Tustin, Section 4616(1) bans using a loudspeaker, sound amplifier, radio or phonograph to broadcast sound onto the public streets for commercial advertising above the Section 4614/4615 decibel limits. Ordinary amplified music elsewhere falls under those same zone noise standards instead.
(1)Loudspeakers, amplifiers used for advertising. The using, operating or permitting to be played, used, or operated of any radio receiving set, musical instrument, phonograph, loudspeaker, sound amplifier, or other machine or device for the producing or reproducing of sound in excess of the levels described in sections 4614 and 4615 which sound is cast upon the public streets for the purpose of commercial advertising or attracting the attention of the public to any commercial building or structure.
Full Breakdown
Tustin's disturbing-noises section, Section 4616, singles out one specific amplified-sound use for its own ban: any radio receiving set, musical instrument, phonograph, loudspeaker or sound amplifier played, operated or permitted to operate in excess of the levels described in Sections 4614 and 4615, where the sound is cast upon the public streets for commercial advertising or to attract public attention to a commercial building or structure. Outside that advertising context, amplified music and sound equipment are governed by the general exterior standards in Section 4614 (55-70 dB(A) depending on zone, with a five dB(A) cut for music) and the interior standards in Section 4615.
Section 4617 exempts outdoor gatherings, public dances, shows and sporting or entertainment events from the chapter, but only where the event is held under a permit issued under Article 3, Chapter 2 for the staging of such events, so a permitted concert or festival is not automatically bound by the Section 4616(1) advertising cap. A business playing music through exterior speakers to draw in customers, without a special event permit, is squarely within Section 4616(1) once the sound exceeds the applicable zone limit and reaches the street.
Violations & Fines
Violating Section 4616(1) is a misdemeanor under Section 4625, with each day of continued use of the loudspeaker or amplifier treated as a separate offense. Tustin Police Department and Community Development respond to complaints and can measure the sound against the Section 4614/4615 limits using a sound level meter under Section 4620 before issuing a citation.
