Cowpens, SC Noise Levels
Cowpens, SC: what the federal noise map shows
Cowpens, 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 Cowpens, not a street-by-street survey of the whole place.
