Vista, CA Noise Levels
Vista, CA: what the federal noise map shows
Vista, CA reads 57.5 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. Road traffic drives that number here, not the other two sources. That's the reading at Vista's Census-defined center point, not any one street, BTS's map is a live raster, not a per-address service.
