Georgetown, SC Noise Levels
Georgetown, SC: what the federal noise map shows
Georgetown, SC reads 52.5 dB(A) on BTS's 24-hour average, inside HUD's "Acceptable" noise zone, 65 dB(A) day-night average or below under 24 CFR 51.104, the federal government's own line for building housing with no extra sound attenuation required. Road traffic drives that number here, not the other two sources. That figure is sampled at one coordinate, the Census Bureau's own internal point for Georgetown, not a street-by-street survey of the whole place.
