Ogden, IA Noise Levels
Is Ogden, IA noisy?
Ogden, IA'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. Ogden's reading comes from a single sampled point, not a block-by-block sweep, so a specific address here could genuinely differ.
Ogden'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.
