Sleepy Hollow, NY Noise Levels
Sleepy Hollow, NY: what the federal noise map shows
Sleepy Hollow, 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. Rail traffic drives that number here, not the other two sources. This describes Sleepy Hollow as a whole, not a specific block, the underlying BTS map resolves to about 38 meters per pixel, sampled at the town's own center point.
Sleepy Hollow's noise, by source
Each of the three transportation modes gets its own model from BTS; the combined figure above is what they add up to.
What this means for a house here
That also clears FHWA's own 66 dB(A) impact threshold for residential land use (23 CFR 772, Table 1), the level highway agencies use to decide whether a new road needs a sound wall. The same window and door upgrades that work on road noise also cut broadband rail noise, though very low-frequency freight rumble travels through walls, not just glass.
