Summary
Sterling Heights lets officers cite booming stereos on rhythmic bass alone -- they don't have to identify the song, lyrics, or artist to prove a 'plainly audible' noise violation.
For purposes of this section, the phrase PLAINLY AUDIBLE means any sound that can be detected by a person using his or her unaided hearing faculties. The enforcing officer need not determine the title of a specific sound, specific words, or the performing artist, and the detection of the rhythmic bass component of music is sufficient to constitute a plainly audible sound.
(d) For violations of this subsection involving broadcasts from a motor vehicle, the operator of the motor vehicle shall be presumed to have dominion and control over the source of the broadcast, and shall therefore be presumed to be responsible for the violation. Passengers, or others lacking an ownership interest, may be found guilty of violating this subsection if such persons had constructive dominion and control over the source of the broadcast, or otherwise aided and abetted the operator.
(e) This subsection shall not be applicable to mobile sound amplification for which a valid city permit has been issued, or for which such sound amplification is incidental to and appropriate for the use of a valid city permit, such as for parades, ice cream trucks, and similar activities, so long as such activities comply with the terms of any such city permit.
(f) A violation of this subsection shall be punishable by a fine of not less than $100. A second violation shall be punishable by a fine of not less than $200. A third or subsequent violation shall be punishable by a fine

Full Breakdown
City Code § 31-4(9)(c) defines PLAINLY AUDIBLE as any sound detectable using unaided hearing, and states specifically that detecting the rhythmic bass component of music -- the low-frequency thump audible through walls or vehicle doors -- is sufficient on its own to meet that standard. An enforcing officer doesn't have to identify the song title, lyrics, or performing artist, which makes bass-heavy car and portable stereo systems straightforward to cite under the mobile sound amplification rules in § 31-4(9).
Violations & Fines
Enforced as part of § 31-4(9): $100 minimum for a first offense, $200 for a second, and $300 plus up to 90 days in jail for a third or later violation.
