Eagan, MN Noise Levels
Eagan, MN: what the federal noise map shows
Eagan, MN 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. Aircraft drives that number here, not the other two sources. This describes Eagan 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.
Eagan'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
Aircraft noise is intermittent and lower-frequency, which is why FAA’s Part 150 program funds whole-envelope sound insulation for homes inside an airport’s own mapped noise contour rather than relying on window replacement alone.

Among the 3,622 US places in this dataset with any measurable transportation noise, Eagan ranks 1,893, loudest first. About 67,240 people live there, making it the 583th largest place in this dataset.
Your street may differ from Eagan's reading
For a single house or lot in Eagan rather than the town-wide figure above, BTS's own map is the same free source, queried directly.
