Forest Park, IL Noise Levels
Is Forest Park, IL noisy?
Forest Park, IL reads 47.5 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 figure is sampled at one coordinate, the Census Bureau's own internal point for Forest Park, not a street-by-street survey of the whole place.
