Mount Holly Springs, PA Noise Levels
How loud is Mount Holly Springs, PA?
BTS only publishes Mount Holly Springs, PA in the 60-69.9 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 "Acceptable" (65 dB(A) or below) or "Normally Unacceptable" (65-75 dB(A)) under 24 CFR 51.104. The main source is rail traffic, well ahead of the other two modes BTS tracks. Treat this as Mount Holly Springs's one representative point, not a promise about every block in it, BTS's map wasn't built to resolve individual streets.
