Summary
Charleston County bans playing a vehicle radio or stereo loud enough to be "plainly audible at a distance of 50 feet in any direction from the vehicle" or inside another dwelling, under County Code § 3-41, with the rhythmic bass alone enough to prove a violation; emergency vehicles are exempt while on duty.
Sec. 3-40. - Definition. As used below, plainly audible means any sound that can be detected by a person using his or her unaided hearing facilities. Sec. 3-41. - Noise—Amplified sound from vehicles. It shall be unlawful for any person to play, operate, or cause to be played or operated, any radio or other vehicular music or sound amplification or reproduction equipment in such a manner as to be plainly audible at a distance of 50 feet in any direction from the vehicle or plainly audible within the residential dwelling of another. The detection of the rhythmic bass component of the music or sound is sufficient to constitute a plainly audible sound. Prohibitions contained in this section shall not be applicable to emergency or public safety vehicles for sound emitted during job-related operation.

Full Breakdown
" Section 3-41 then makes it "unlawful for any person to play, operate, or cause to be played or operated, any radio or other vehicular music or sound amplification or reproduction equipment in such a manner as to be plainly audible at a distance of 50 feet in any direction from the vehicle or plainly audible within the residential dwelling of another," and specifies that "the detection of the rhythmic bass component of the music or sound is sufficient to constitute a plainly audible sound," so officers do not need to identify the song or measure decibels to cite a driver.
" Violations are punished under § 3-45 as a misdemeanor, and a resident specifically harmed by vehicle noise may also sue directly to stop it under § 3-46.
Violations & Fines
Any person who violates the vehicle-noise provisions shall be guilty of a misdemeanor and, upon conviction, subject to a fine of not more than $500.00 or not more than 30 days in jail, or both, under § 3-45, and each occurrence can be cited separately. A neighbor "specifically damaged" by the noise can also bring a civil suit in magistrate or circuit court under § 3-46 to force it to stop, on top of any county citation.
