Cambridge, MD: what the federal noise map shows
At Cambridge, MD, road, rail and aircraft noise all fall below the 45 dB(A) floor BTS's national map can distinguish from silence. That figure is sampled at one coordinate, the Census Bureau's own internal point for Cambridge, not a street-by-street survey of the whole place.
