Union Gap, WA Noise Levels
How loud is Union Gap, WA?
At 47.5 dB(A), Union Gap, WA falls 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. The main source is aircraft, well ahead of the other two modes BTS tracks. That figure is sampled at one coordinate, the Census Bureau's own internal point for Union Gap, not a street-by-street survey of the whole place.
Where Union Gap's noise comes from
BTS models these three sources separately before combining them, so a place can be quiet on two and loud on the third.
If you're weighing a move to Union Gap
