Best use for travel intelligence

For travel decisions, noise-monitor station pages help show whether a place has official ambient-noise evidence nearby, how noisy that station has been, and how much uncertainty remains between the station and the actual room or street.

What this changes for travelers

  • Official stations: Show where real ambient-noise monitoring exists and what those stations have seen recently.
  • Historical Leq: Useful for checking whether a noisy road, district, or neighborhood stays loud over time.
  • Station gaps: The absence of a station is itself important because many hotel or neighborhood pages will need lower confidence.

Best sources to start with

  • Best current station source: PCD Noise4Thai for official station snapshots, hourly values, and area-type context.
  • Best historical archive: PCD noise monitor CSV for daily Leq station history and year-over-year comparisons.
  • Best open mapping supplement: OSM noise monitoring stations for geospatial enrichment when station coordinates or nearby source context need map support.
  • Best developer starting point: Keep Leq 24hr, hourly Leq, Lmin, Lmax, and L90 as separate metrics with explicit timestamps and preliminary flags.
Official / agency sources

2 of 3 sources look official or agency-backed.

API/feed candidates

3 sources expose API, feed, CKAN/DataStore, JSON, XML, or similar machine-readable access.

Near-real-time signals

1 sources have live, hourly, event-driven, warning, or frequent update language.

Developer note

Store station metadata, metric type, observation time, and preliminary-flag status separately, and do not confuse station history with a full neighborhood noise map.

Last checked and source confidence

Last checked: 2026-05-11.

Source confidence: This cluster is strongest when several sources describe the same traveler problem from different angles: official context, machine-readable feeds, and slower fallback documentation.

Geospatial and satellite

OSM noise monitoring stations

Geospatial enrichment for man_made=monitoring_station with monitoring:noise tagging, useful for mapping public or private noise-monitoring locations and nearby source context.

OpenStreetMap Overpass API and ODbL geospatial data Weather, environment, and disasters

PCD noise monitor CSV

Historical daily average Leq data from Pollution Control Department noise-monitoring stations, typically published as yearly CSV files for nationwide station records.

CKAN dataset with CSV download resources Weather, environment, and disasters

PCD Noise4Thai

Official Pollution Control Department ambient-noise monitoring surface with station codes, area type, update time, Leq 24hr, hourly Leq, Lmin, Lmax, and station detail views. Daily station data is presented as preliminary monitoring data.
