Carmichael FAQ
How loud is 55 dBA?
55 dBA is roughly the sound level of a normal conversation at 3 feet, or a quiet suburban street. It's the §6.68.070 daytime cap at the neighbor's residential property line.
Does Sacramento County use dBC like Sarasota or San Diego?
No, SCC §6.68.070 uses dBA only - it doesn't add a low-frequency dBC supplement, so subwoofer bass that doesn't trip the A-weighted meter may not be a citable violation absent neighbor-disturbance evidence.
