Mount Sterling, IL Noise Levels
Mount Sterling, IL: what the federal noise map shows
Mount Sterling, IL 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.
