Cranston, RI Noise Levels
Cranston, RI: what the federal noise map shows
Cranston, RI reads 47.5 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. Treat this as Cranston's one representative point, not a promise about every block in it, BTS's map wasn't built to resolve individual streets.
