Salem, MO Noise Levels
How loud is Salem, MO?
BTS only publishes Salem, MO 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. Salem's reading comes from a single sampled point, not a block-by-block sweep, so a specific address here could genuinely differ.
Where Salem's noise comes from
BTS models these three sources separately before combining them, so a place can be quiet on two and loud on the third.
If you're weighing a move to Salem
Depending on where in that band the true value sits, it may also clear FHWA's 66 dB(A) residential impact threshold (23 CFR 772, Table 1), the trigger highway agencies use for sound-wall decisions. Upgraded windows, door seals and STC-rated glazing meaningfully cut broadband, near-continuous road noise.

Salem's number isn't a one-off calculation, it comes from the same method covered in the methodology guide. The guide to what actually cuts each kind of noise explains why road traffic calls for a different fix than the other two sources.
