Alburnett, IA Noise Levels
Alburnett, IA: what the federal noise map shows
Alburnett, IA reads 57.5 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 Alburnett 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.
Alburnett's noise, by source

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.
