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