Atwood, IL Noise Levels
Atwood, IL: what the federal noise map shows
Atwood, 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. Rail traffic drives that number here, not the other two sources.
That's the reading at Atwood's Census-defined center point, not any one street, BTS's map is a live raster, not a per-address service.
Atwood's noise, by source
Each of the three transportation modes gets its own model from BTS; the combined figure above is what they add up to.
What this means for a house here
The same window and door upgrades that work on road noise also cut broadband rail noise, though very low-frequency freight rumble travels through walls, not just glass.
