Athens, TN Noise Levels
Athens, TN: what the federal noise map shows
Athens, TN's 70-79.9 dB(A) band spans one of HUD's zone boundaries, so the honest answer is a range: somewhere between "Normally Unacceptable" (65-75 dB(A)) and "Unacceptable" (above 75 dB(A)), not one clean verdict. Rail traffic drives that number here, not the other two sources. That figure is sampled at one coordinate, the Census Bureau's own internal point for Athens, not a street-by-street survey of the whole place.
Athens'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
That also clears FHWA's own 66 dB(A) impact threshold for residential land use (23 CFR 772, Table 1), the level highway agencies use to decide whether a new road needs a sound wall. 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.

Your street may differ from Athens's reading
For a single house or lot in Athens rather than the town-wide figure above, BTS's own map is the same free source, queried directly.
