Rockdale County, GA Noise from Specific Sources: Low-Frequency Bass Limits (2026)

Rockdale County has no ordinance devoted specifically to low-frequency or subwoofer noise; the only place the Code addresses bass by name is inside the motor-vehicle noise rule at section 42-1(b). That subsection prohibits operating musical equipment in or on a motor vehicle so that it is plainly audible at a distance of 100 feet from the point of origin, and then defines what "plainly audible" requires: the words or phrases produced need not be discernible, and the definition expressly states that bass reverberations may be included in meeting the standard.

In practice, that means a vehicle's stereo can violate the ordinance purely on the strength of its bass output, felt or heard as reverberation 100 feet away, even if an officer cannot make out a single lyric. The same reasoning does not automatically carry over to a stationary sound system on residential or commercial property: subsections (d) through (f) use a property-line audibility test rather than the 100-foot vehicle test, but they share the same underlying "plainly audible" concept defined once, at the top of section 42-1, for the whole article.

There is no separate decibel-based low-frequency standard, no measured frequency band and no special equipment listed for subwoofers; the county regulates bass the same way it regulates any other audible sound: through whether an ordinary listener can perceive it at the specified distance or property line.
