Low-Frequency Bass Limits
Marietta's noise code sets a separate, higher decibel ceiling for bass-heavy, low-frequency sound using C-weighting, which barely filters out very low frequencies the way the standard A-weighted limit does. Table 1 of City Code § 10-6-030 caps residential and commercial property at 84 dBC by day and 79 dBC at night, with industrial property capped at 89 dBC at all times.
