Noise Level

x402 APIPassing, checked 2 h ago

Queries the Sensor.Community live area feed, keeps the newest noise reading per outdoor sensor within the requested radius, and returns nearest readings plus median, p10 and p90 LAeq. It never converts missing sensors into an estimated dB value. Community sensors are indicative rather than calibrated regulatory measurements; no day/night legal limit or property valuation is inferred.
