Summary
Oakland bans operating any aircraft, a term the code defines to include helicopters, over the city with sound-amplifying equipment running. OMC § 8.18.100 makes it unlawful citywide to broadcast music, voice, or other noise from an airborne loudspeaker, though it doesn't reach ordinary flight or engine noise, which the FAA controls.
No person shall operate, or cause to be operated, any aircraft for any purpose in or over the city with sound-amplifying equipment in operation. "Aircraft" as used in this section means any contrivance now known or hereafter invented, used, or designated for navigation or for flight in the air. The word "aircraft" shall include helicopters and lighter-than-air dirigibles and balloons. "Sound-amplifying equipment" as used in this section means any machine or device for the amplification of music, the human voice, or any other noise or sound. "Sound-amplifying equipment" shall not be construed as including warning devices on authorized emergency aircraft or any horns, or other warning device used only for traffic safety purposes.

Full Breakdown
100 provides simply that no person shall operate, or cause to be operated, any aircraft for any purpose in or over the city with sound-amplifying equipment in operation. The ordinance defines 'aircraft' broadly as any contrivance now known or hereafter invented, used, or designated for navigation or flight in the air, and specifies that the term 'shall include helicopters and lighter-than-air dirigibles and balloons', so a helicopter broadcasting music or announcements over Oakland falls squarely within the ban. 'Sound-amplifying equipment' is defined as any machine or device for the amplification of music, the human voice, or any other noise or sound, but the section carves out warning devices on authorized emergency aircraft and any horn or other device used only for traffic safety purposes.
Because this section addresses only amplified sound broadcast from an aircraft, it does not regulate helicopter engine noise, rotor noise, altitude, or flight paths, those are federally preempted areas under FAA jurisdiction, and Oakland's ordinance leaves them untouched. 18 among the 'Public Welfare, Morals and Policy' infraction categories.
