Harrison, NY Noise Levels
Is Harrison, NY noisy?
Harrison, NY'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. Treat this as Harrison's one representative point, not a promise about every block in it, BTS's map wasn't built to resolve individual streets.
