Manchester, NH Noise Levels
How loud is Manchester, NH?
BTS's tiles come back blank for Manchester, NH on road, rail and aircraft alike, its own way of reporting "quieter than 45 dB(A)."
That's the reading at Manchester's Census-defined center point, not any one street, BTS's map is a live raster, not a per-address service.

Checking one address in Manchester
Nothing here substitutes for checking one address in Manchester directly, and BTS's own map lets anyone do that at no cost.
Manchester's number isn't a one-off calculation, it comes from the same method covered in the methodology guide. See the why New York City shows up quiet here too for why a real place can show no reading at all.
