Franklin Grove, IL Noise Levels
Noise levels in Franklin Grove, IL
BTS only publishes Franklin Grove, IL in the 70-79.9 dB(A) band, which straddles HUD's own dividing line: depending on exactly where in that range the true 24-hour average falls, this reads as "Normally Unacceptable" (65-75 dB(A)) or "Unacceptable" (above 75 dB(A)) under 24 CFR 51.104. The main source is rail traffic, well ahead of the other two modes BTS tracks. That's the reading at Franklin Grove's Census-defined center point, not any one street, BTS's map is a live raster, not a per-address service.
