Belgrade, MT Noise Levels
Is Belgrade, MT noisy?
Belgrade, MT reads 52.5 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. That's the reading at Belgrade's Census-defined center point, not any one street, BTS's map is a live raster, not a per-address service.
Belgrade'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.
