Carlsbad, CA Noise Levels
Noise levels in Carlsbad, CA
BTS only publishes Carlsbad, CA 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 aircraft, well ahead of the other two modes BTS tracks. This describes Carlsbad 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 Carlsbad'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 Carlsbad
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. Aircraft noise is intermittent and lower-frequency, which is why FAA’s Part 150 program funds whole-envelope sound insulation for homes inside an airport’s own mapped noise contour rather than relying on window replacement alone.
