Around Suvarnabhumi, noise maps and monitoring reports help describe aircraft sound. Check what a contour means and where it applies. A reading at the airport cannot stand for every nearby home or hotel.
Check where, when and how the sound was measured. A station reading, a complaint, and a model are different kinds of evidence. Road noise, aircraft noise, and workplace noise can use different measures too. Check the source first, then use the record to judge a room or a street.
Map data marking noise barriers, walls built to block sound, near roads, rail lines, airports, and neighbourhoods.
Access: OpenStreetMap's Overpass tool, under an open map-data licence. Updates: Edited by volunteers, so it can change at any time.
Thailand's Pollution Control Department runs this official noise-monitoring site. Each station has a code, an area type, and a last-update time. Stations also show sound levels: the average over 24 hours, the average for one hour, and the lowest and highest levels seen. Daily figures are marked as early, not final.
Access: A public dashboard and station pages. No bulk API is confirmed. Updates: Live snapshots. Some stations add hourly and daily detail too.
Past daily noise readings from Pollution Control Department stations across the country. These are usually published once a year, as files you can download.
Access: A government data listing with file downloads. Updates: Daily to yearly, depending on when each file comes out.
