Aurora, SD Noise Levels
Is Aurora, SD noisy?
Aurora, SD 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. Rail traffic drives that number here, not the other two sources. This describes Aurora as a whole, not a specific block, the underlying BTS map resolves to about 38 meters per pixel, sampled at the town's own center point.
Aurora'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.

Behind Aurora's reading
The methodology guide shows exactly how Aurora's reading was built from BTS's tile data. Since rail traffic is what's driving this reading, the guide to what actually cuts each kind of noise covers the fix that fits.
