North Las Vegas, NV Noise Levels
North Las Vegas, NV: what the federal noise map shows
North Las Vegas, NV'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. Road traffic drives that number here, not the other two sources. That figure is sampled at one coordinate, the Census Bureau's own internal point for North Las Vegas, not a street-by-street survey of the whole place.
North Las Vegas'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. Upgraded windows, door seals and STC-rated glazing meaningfully cut broadband, near-continuous road noise.
