Opelousas, LA Noise Levels
How loud is Opelousas, LA?
BTS only publishes Opelousas, LA 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 road traffic, well ahead of the other two modes BTS tracks. This describes Opelousas 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.
Where Opelousas's noise comes from
