# `--traffic` Extension — Transport-Noise Layer (Flight · Rail · Wind-Turbine Acoustic Exposure) Where FLIGHT, RAIL, and WIND-TURBINE acoustic exposure is actually published per country — strategic noise maps (Lden/Lnight contours), the kind of public viewer that exists, and the wind-turbine dB statutes — and, more importantly, **which kind of noise-map system** the country runs, because that determines whether an address-precise contour exists at all. Loaded when `--traffic` is invoked. **Snapshot**: June 2026. **Scope**: this is the *acoustic-map* layer of `--traffic`. The core `--traffic` section already emits a single ROAD-noise verdict (🟢 silent / 🟡 light / 🟠 audible / 🔴 nuisance) **derived from vehicle counts** (TMJA / AADT / DTV / TGM / IMD) — count-inferred, road-only. This extension adds the **other three noise modes** — aircraft, rail, and wind turbine — read from **published strategic noise maps + statutes**, a higher-tier address-resolving primary artefact roads never had here. **Distinct from the road-count verdict** (that infers noise from a count; this reads an actual published Lden/Lnight dB band). **Distinct from `--risks`** (natural + technological hazards — gets a one-line cross-ref only). It pairs with `--traffic` (parent — the road verdict), `--amenities` (OSM proximity is the engine of the honest tail), and `--climate` (storm-season grid/airport disruption is a separate surface). > **DECISION CAVEAT — read before quoting any number.** A strategic noise map is a **4.0 ± 0.2 m façade-height contour computed under CNOSSOS-EU** (END Annex II), *not* a measurement at this parcel. Report the map **BAND**, never a parcel-precise figure: write *"the address falls in the 55–59 Lden band on the `` (strategic-noise-map contour, 4 m height — verify on visit)"*, never *"this house is at 58 Lden"*. This satisfies anti-hallucination Check 2 (no parcel-specific "is" statements) and the address-vs-commune trap — the contour is a road-segment / area-wide source, so the verb stays at map-band level. ## Universal contract For the property's country, return: 1. **System type** (classify first — see the spine below): 🟢 national/regional PUBLIC address-zoomable viewer · 🟡 END-mandated maps exist but only via geoportal/WMS/open-data/per-agglomeration PDFs · 🟠 airport/rail-by-operator only (no national viewer) · 🔴 no public strategic noise map (OSM-proximity + WHO calibration only) 2. **The channel** — the named official viewer/portal + URL where one exists, OR the honest fallback (*"no national strategic noise map published — assess via `--amenities` OSM proximity + WHO 2018 thresholds; request operator contours; verify on visit"*). Never invent a viewer URL. 3. **Modes covered** — road / rail / aircraft / industry / wind, individually or combined — and which mode is **excluded** (e.g. UK Extrium excludes aircraft). 4. **Indicators** — Lden + Lnight (and the local label: CZ Ldvn/Ln, SI Ldvn/Lnoč, HU Lden/Léjjel, RO Lzsn/Lnoapte, FI Lden/Lyö — all the END Lden/Lnight pair; quote verbatim, then gloss). Switzerland uses Swiss **Lr** (LSV/OPB), **NOT** EU Lden — the dB bands are *not* comparable. 5. **Wind-turbine statute** (where confirmed) — the dB **limit** is a statute value, **citable as fact**; per-address exposure is **not** (that is a modelled prognosis, verify on consent conditions). 6. **The verdict** — the map BAND vs the WHO 2018 health threshold for that mode → 🟢🟡🟠🔴 (computed comparison, both numbers shown inline). 7. **Confidence** — HIGH / MEDIUM / LOW per the skill's contract. ## The system spine (classify first) Whether an address-precise contour exists is set by the **public-access channel**, not by whether the maps legally exist. In the EU/EEA the maps are *always* mandated by law; the question is whether you can *see* them at a building footprint: - **🟢 PUBLIC ADDRESS-ZOOMABLE VIEWER (road+rail+air)** — one government/regulator/public-body site lets a citizen zoom to a building footprint and read the Lden/Lnight band per mode, citable as the primary contour source. The confirmed-good set: **US (BTS), FR (Île-de-France — Bruitparif), DE (UBA+EBA), NL (Atlas Leefomgeving / RIVM), IE (EPA), AT (Lärminfo.at), ES (SICA/CEDEX), BE-Brussels (Geobru), DK (MiljøGIS), EE (Maa-amet Mürakaart), CZ (MZ geoportal), SI (ARSO Atlas okolja), HU (zajterkepek.hu), HR (HAOP/MINGOR), CH (SonBASE / map.geo.admin.ch — Swiss Lr, not Lden)**. UK-England (Extrium) sits here **with one exclusion**: road+rail only, **aircraft EXCLUDED**. - **🟡 END-MANDATED, DATA EXISTS, BUT NO FRIENDLY NATIONAL VIEWER** — the EU END Directive *legally mandates* the maps and they are *published*, but public access is via geoportal/WMS/open-data/per-operator/per-agglomeration PDFs, not a single address-zoomable consumer viewer. **PT (APA PDFs), LU, MT, IT (per-comune), CY, PL, LT, LV, SK, FI, NO, SE, RO, BG, GR, IS, BE-Flanders/Wallonia.** The data exists — open the national geoportal / operator page and toggle the Lden/Lnight layer; the **EEA Noise Viewer ([noise.eea.europa.eu](https://noise.eea.europa.eu))** is the cross-EU/EEA fallback aggregating reported END contours. Never render any of these as "no map published". - **🟠 AIRPORT/RAIL-BY-OPERATOR ONLY (no national viewer)** — outside the EU/US, aircraft (and sometimes rail) noise is published **per airport / per district plan**, not on a national viewer. **CA (Transport Canada NEF/NEP, airport-by-airport, voluntary), AU (ANEF charts per airport master plan + AS 2021:2015), NZ (NZS 6805:1992 ANB/OCB via district plans), UK-aircraft (DfT/CAA-ERCD + operator contours for Heathrow/Gatwick/Stansted).** Pull the contour for the **specific airport / district plan**; there is no national portal. - **🔴 NO PUBLIC STRATEGIC NOISE MAP** — almost the entire non-EU / non-US / non-UK corpus (Caribbean, most of MENA, most of Asia, LatAm, Africa, Pacific) + the non-END microstates (AD/MC/SM/LI). No national strategic noise map and no citable national aircraft-noise standard confirmed. The honest output is OSM-proximity (`--amenities`) + WHO 2018 thresholds + "request operator-published contours where a major airport/rail/wind farm is within range; verify on visit" — **never a fabricated portal or a guessed dB band**. ## Verdict bands Translate the **WHO 2018 Environmental Noise Guidelines for the European Region** ([who.int/europe/publications/i/item/9789289053563](https://www.who.int/europe/publications/i/item/9789289053563), released 30 Jan 2019; cross-confirmed by the EEA) into the skill's 🟢🟡🟠🔴 by mode. WHO recommends reducing each source **below** these levels to protect health — they are **health thresholds, NOT legal limits** (distinct from the citable wind *statutes* below). The verdict is a **computed comparison**: the map BAND minus the WHO value for that source. Show both numbers inline so the user can reverse the math. **WHO 2018 thresholds** (recommend keeping exposure below): | Source | Lden threshold | Lnight threshold | |---|---|---| | Road traffic | < 53 dB | < 45 dB | | Railway | < 54 dB | < 44 dB | | Aircraft | < 45 dB | < 40 dB | | Wind turbine | < 45 dB (Lden) | *(no separate WHO Lnight value set)* | > **Caveat on the wind 45 Lden figure**: the WHO landing page confirms wind turbine is one of the four covered sources, but the EEA page did not repeat the number — **re-quote the 45 Lden from the full WHO 2018 PDF before printing it as hard fact**. The road/rail/aircraft values are EEA-cross-confirmed and stand. **Band mapping** (delta of the map BAND over the WHO threshold for that mode): | Band | Trigger | Read | |---|---|---| | 🟢 | Map band is **below** the WHO threshold for that source | "Below the WHO health threshold for `` on the `` contour — note as a strength. Still verify on visit." | | 🟡 | Map band is **0–5 dB over** the WHO threshold | "Marginally above the WHO `` threshold (map band X vs WHO Y). Audible; monitor — glazing/orientation usually sufficient." | | 🟠 | Map band is **5–10 dB over** the WHO threshold | "Meaningfully above WHO `` (band X vs Y). Plan/budget acoustic glazing + façade; pull the operator contour and assess on visit." | | 🔴 | Map band is **>10 dB over** the WHO threshold, OR inside a statutory air-noise restriction zone (CA NEF >30, AU >20–25 ANEF, NZ inside ANB 65 dB Ldn) | "Significant — band X vs WHO Y, or inside a land-use noise-restriction contour. Aircraft Lnight especially drives sleep disturbance. Test/inspect; may walk away if unmitigatable." | > **Lnight drives sleep disturbance more than Lden.** A 🟢 Lden can still hide a 🟠/🔴 Lnight — always read **both** indicators. Aircraft Lnight (WHO <40, the strictest threshold) is the one that most often flips an otherwise-quiet address. ## Wind-turbine statute table (dB LIMITS are citable as fact; per-address exposure is NOT) These are **statute / standard values** — the statute IS the source, so they are citable as fact per the anti-hallucination contract. What is **not** citable is the *measured exposure at this house*: that is a modelled immission prognosis (DIN ISO 9613-2 / emergence measurement) verified against consent conditions — `(modelled — verify on the consent / permit file)`. | Jurisdiction | Instrument | Limit | Source | |---|---|---|---| | **DK** Denmark | Statutory Order **nr. 135 af 07/02/2019** (Danish EPA / Miljøstyrelsen) | Total outdoor: **39 dB(A)** residential / **44 dB(A)** open country @8 m/s; 37 / 42 @6 m/s.

Do NOT invent a dB or a statute number. ## ⚠️ 7 cross-cutting traps 1. **"There's a digital portal" ≠ "there's an address-precise dB you can cite at this parcel."** Every strategic noise map is a **4.0 ± 0.2 m façade-height contour** under CNOSSOS-EU (END Annex I/II) — an area-wide artefact, not a measurement at this house. The NL Atlas Leefomgeving says it itself: the map *"gives only a general picture and is NOT suitable for checking against legal standards such as façade noise load (gevelbelasting)"*. The US BTS viewer carries the same caveat: *"should not be used to evaluate noise levels in individual locations."* Quote the **band**; tag `(strategic-noise-map contour, 4 m height — verify on visit)`. 2. **The UK Extrium viewer EXCLUDES aircraft.** [extrium.co.uk/noiseviewer.html](http://www.extrium.co.uk/noiseviewer.html) maps England road + railway + Noise Important Areas only — **aircraft/aviation noise is published separately** by airport operators / DfT. Wherever aircraft noise is the buyer's concern (e.g. anywhere near Heathrow/Gatwick/Stansted), do **not** conclude "no aircraft noise" from a clean Extrium screen — point to the DfT/CAA-ERCD and operator-published contours instead. 3. **END maps are 4 m strategic contours, not a parcel certificate — and the "major" thresholds gate WHICH sources get a map.** END mandates maps only for agglomerations >100,000 inhabitants, major roads >3M veh/yr, major rail >30k trains/yr, major airports >50k movements/yr. **Below those thresholds, even an EU address may have NO mapped contour by design** — a rural dwelling outside the agglomeration/corridor collapses to the honest-tail template (OSM proximity + WHO). Don't over-promise the EU core. 4. **A wind statute LIMIT ≠ the measured exposure at this house.** DK 39/44, UK ETSU 35–40/43, DE TA Lärm 35, NL 47/41 are the *permitted ceilings* — citable as fact. Whether *this* dwelling actually sits at/under that ceiling is a modelled immission prognosis verified against the consent conditions, and France doesn't even use a fixed ceiling (it's an **emergence** rule — ambient-with-turbine minus background). Cite the statute as the limit; flag the actual exposure as `(modelled — verify on the consent/permit file)`. 5. **The `--traffic` road-count verdict ≠ an acoustic map — and Swiss Lr ≠ EU Lden.** The parent `--traffic` road verdict is *inferred from a vehicle count* (TMJA/AADT/DTV), road-only; this extension reads an *acoustic Lden/Lnight contour* for rail+air+road. Keep the two surfaces labelled. Separately, **Switzerland is the one non-END entry** — SonBASE / map.geo.admin.ch publishes Swiss **Lr (Beurteilungspegel, LSV/OPB)** day/night, **NOT** EU Lden — the dB bands are **not** comparable and must not be translated through EU/WHO Lden tables without flagging the metric difference. 6. **CA NEF / AU ANEF / NZ ANB-OCB are airport-specific land-use contours, not national viewers — and they carry their own restriction thresholds.** Canada (Transport Canada NEF: no new residential where NEF >30; complaints high >35) and Australia (ANEF: a site outside the **20 ANEF** contour generally needs no aircraft-specific construction protection, per AS 2021:2015) and New Zealand (NZS 6805:1992: **Air Noise Boundary 65 dB Ldn**, **Outer Control Boundary 55 dB Ldn** — noise-sensitive activities prohibited inside the ANB) are **per-airport / per-district-plan**, voluntary or council-discretion. Mark 🟠 and pull the contour for the *specific* airport / district plan. (NZ ANB/OCB values are from a SECONDARY reference — Environment Guide — pending the paywalled standard or a primary council district-plan rule.) 7. **Lnight drives sleep disturbance more than Lden — and the night band is the one most often omitted.** The Lden indicator carries a +5 dB evening / +10 dB night penalty already, but the *separate* Lnight layer (WHO aircraft <40, the strictest of all four sources) is what governs sleep. A coverage caveat compounds this: agglomeration-scoped maps (e.g. HU zajterkepek.hu, and many 🟡 geoportal layers) cover only cities >100k + major corridors — **a rural address outside those bands has no mapped Lnight contour at all**; the honest output there is the OSM-proximity + WHO template, not silence. ## Regional patterns + country one-liners The 6 region blocks below cover the named jurisdictions (mirroring `auction-registry.md`'s blocks) and, together with the system-spine classification, span all 126 supported countries. Each line: **band · channel (URL where confirmed) or honest fallback · modes/indicator note**. Where no national viewer was confirmable it is marked 🟡 (data exists, geoportal/operator) or 🔴 (no map) honestly rather than guessed. **Any END country not given a dedicated line below falls to the 🟡 system-spine classification + the EEA Noise Viewer ([noise.eea.europa.eu](https://noise.eea.europa.eu)) fallback** — never read the absence of a one-liner as "no map". The non-END microstates and the entire non-EU/non-US/non-UK tail collapse to: *no national strategic noise map — assess via `--amenities` OSM proximity + WHO 2018 thresholds + request operator contours; verify on visit.* --- ## Western Europe + EFTA + microstates + UK + Crown Dependencies - **FR** France — 🟢 (Île-de-France) — **Bruitparif carto** ([carto.bruitparif.fr](https://carto.bruitparif.fr/)): road+rail+air, Lden **and** Lnight, address-lookup to building footprint, CNOSSOS-EU.

OSM-proximity + WHO; request Ben Gurion / operator contours where in range; verify on visit. - **AE · SA · QA · KW · BH · OM · JO · LB · EG · MA · TN** — 🔴 — no national strategic noise map or published aircraft-noise contour located. Assess via `--amenities` OSM proximity (airport/rail/major-road polylines) + WHO 2018 thresholds (road <53/<45, rail <54/<44, aircraft <45/<40, wind <45 Lden); request operator-published contours where a major airport/rail/wind farm is within range; verify on visit. ### Confidence 🔴 honest across the block — no strategic noise map or national aircraft standard confirmed for any MENA/GCC/IL/TR jurisdiction this pass. The verdict collapses to OSM-proximity + WHO calibration + request-operator-contours; no portal or dB band is invented. Confidence on the *absence* finding: MEDIUM (well-supported structurally; a per-airport contour may exist for a specific major hub and should be requested). --- ## APAC + South Asia No EU END mandate. The one structured channel here is **aircraft land-use contours, airport-by-airport** (AU/NZ); the rest is the honest tail. - **AU** Australia — 🟠 (aircraft) / 🔴 (road/rail acoustic map) — **ANEF charts** per airport (Airservices-endorsed, in approved master plans; [airservicesaustralia.com](https://www.airservicesaustralia.com/industry-info/anefs-and-aneis/)); units 15/20/25/30/35/40; **AS 2021:2015** building-siting (outside 20 ANEF = no aircraft-specific protection). Road: **NSW TfNSW corridor maps** ([transport.nsw.gov.au traffic-volume](https://www.transport.nsw.gov.au/operations/roads-and-waterways/environment-and-heritage/reducing-road-traffic-noise/traffic-volume), SEPP trigger 10,000–20,000 AADT — a corridor/trigger map, NOT an Lden viewer).

No national viewer — **check the relevant district plan**. - **JP · KR · TW · HK · MO · SG · TH · MY · ID · VN · PH · CN · KH · IN · LK · MV** — 🔴 — no national strategic noise map or published aircraft-noise contour located this pass. Assess via `--amenities` OSM proximity + WHO 2018 thresholds; request operator-published contours where a major airport/rail/wind farm is within range (e.g. a major hub may have an EIA-derived contour); verify on visit. ### Confidence 🟠 for AU/NZ aircraft (per-airport land-use contours confirmed; NZ ANB/OCB values SECONDARY pending the paywalled standard or a primary council district-plan rule); 🔴 honest for the rest of APAC + South Asia (no national strategic noise map confirmed — OSM+WHO, never invented). A specific major airport in any of these may have an operator/EIA contour worth requesting. --- ## LATAM + Caribbean No EU END mandate; **no national strategic noise map** or citable national aircraft-noise standard confirmed for any jurisdiction in this block. - **MX · BR · AR · CL · PE · EC · CO · UY · CR · PA · PY** LatAm — 🔴 — no national strategic noise map or published aircraft-noise contour located. Assess via `--amenities` OSM proximity + WHO 2018 thresholds; request operator/airport contours (a major hub or an EIA filing may carry one); verify on visit. - **BS · DO · JM · BB · BZ · KN · AG · LC · GD · AW · CW · SX · BQ · KY · BM · TC · VG** Caribbean — 🔴 — no national strategic noise map confirmed; small-island markets typically have no published acoustic contour. Assess via `--amenities` OSM proximity (airport/main-road polylines) + WHO 2018 thresholds; request airport-operator contours where in range; verify on visit. (Island airports — e.g. a tourism hub close to residential — are the most common real exposure; request the operator/EIA contour.) ### Confidence 🔴 honest across the block — no strategic noise map or national aircraft standard confirmed for any LatAm/Caribbean jurisdiction this pass. The verdict collapses to OSM-proximity + WHO calibration + request-operator/EIA-contours; no portal or dB band is invented. Confidence on the *absence* finding: MEDIUM. --- ## Africa + Anglo-non-EU The US/CA stand apart (US has a true national viewer; CA is airport-by-airport); the rest of the block is the honest tail. - **US** United States — 🟢 — **BTS National Transportation Noise Map** ([maps.dot.gov/BTS/NationalTransportationNoiseMap](https://maps.dot.gov/BTS/NationalTransportationNoiseMap/); provenance [bts.gov/geospatial](https://www.bts.gov/geospatial/national-transportation-noise-map)): **aviation** (FAA AEDT) + **highway** (FHWA TNM + HPMS) + **rail**, zoomable to address, **bi-annual** updates. Official caveat: *"should not be used to evaluate noise levels in individual locations"* → tag `(map contour — verify on visit)`. The single best non-EU public viewer. **Does NOT include wind** (US wind = state patchwork — see table). The originally-briefed `maps.bts.dot.gov/noise/` host refused the headless fetcher; cite the `maps.dot.gov` host as the live viewer. - **CA** Canada — 🟠 (aircraft) — **Transport Canada NEF/NEP** ([tc.canada.ca NEF](https://tc.canada.ca/en/aviation/operating-airports-aerodromes/managing-noise-aircraft/noise-exposure-forecast-related-programs)): cumulative aircraft-noise model, contours NEF 25/30/35/40; **no new residential where NEF >30**; complaints high >35. **NEP** = 10+yr land-use projection variant. **Airport-by-airport, VOLUNTARY** — not a national viewer; obtain per-airport via Transport Canada's Civil Aviation Communications Centre. Road/rail acoustic map: 🔴 (OSM+WHO). (Wind: per-province, not verified this session.) - **ZA · MA · EG · TN · NG · KE · MU · CV · SC · GH · RW** Africa — 🔴 — no national strategic noise map or published aircraft-noise contour located. Assess via `--amenities` OSM proximity + WHO 2018 thresholds; request airport/rail/wind-operator contours where in range; verify on visit. ### Confidence HIGH for US (BTS national viewer confirmed live, modes + bi-annual cadence + caveat documented); 🟠 for CA aircraft (NEF/NEP confirmed, per-airport/voluntary); 🔴 honest for the African corpus (no national strategic noise map confirmed — OSM+WHO, never invented). Several official `.gov`/`.gov.au` pages (bts.gov, transport.nsw.gov.au) 403'd the headless fetcher — these are **bot blocks, not dead links**; do not flag DEAD without a browser-UA re-check. --- ## Universal mitigations Applicable across all 126 countries: 1. **Classify the system before trusting any map** — 🟢 address-zoomable viewer / 🟡 END-mandated-but-geoportal-only / 🟠 airport-by-operator / 🔴 no map. It decides whether you can cite a contour at all, or must fall back to OSM-proximity + WHO. 2. **Read BOTH indicators, and quote the BAND not a point** — Lden *and* Lnight (Lnight drives sleep disturbance; aircraft Lnight WHO <40 is the strictest). Always write the band + `(strategic-noise-map contour, 4 m height — verify on visit)`; never a parcel-precise dB. 3. **In 🟡 markets, open the geoportal / operator layer (or the EEA Noise Viewer)** — the data exists by law; toggle the Lden/Lnight WMS layer on the national geoportal, or use [noise.eea.europa.eu](https://noise.eea.europa.eu) as the cross-EU/EEA fallback that aggregates reported END contours. 4. **For aircraft, pull the airport's own contour** — UK Extrium excludes it; CA/AU/NZ are per-airport land-use contours (NEF / ANEF / ANB-OCB). Get the contour for the *specific* airport / district plan, and check the statutory restriction threshold (NEF >30, 20 ANEF, 65 dB Ldn ANB). 5. **In 🔴 markets, run `--amenities` OSM proximity + WHO calibration** — straight-line distance to the nearest (a) aeroway=aerodrome, (b) railway=rail mainline, (c) highway=motorway/trunk/primary, (d) power=generator + generator:source=wind. Distance + infrastructure class + WHO threshold gives a *directional* verdict ("likely above/below WHO road threshold"), NOT a dB number. Request operator/EIA contours; verify on visit. 6. **Treat a wind statute limit as the ceiling, not the exposure** — DK 39/44, UK ETSU 35–40/43, DE 35, NL 47/41 are permitted limits (citable as fact); FR uses an emergence rule (5 dB day / 3 dB night), not a ceiling. The actual exposure at this dwelling is a modelled prognosis — verify on the consent/permit file. 7. **Re-verify the viewer URL + the mapping round within 30 days of decision-day** — END maps refresh on a 5-yr cycle (latest round 2022; UK/IE Round 4 = 2021 data); viewers move (UBA path, BTS host, SE `/en/guidance/` path). URL-liveness ≠ data-still-current; a fresh round can shift a band. ## Status **Confidence**: HIGH for ~16 jurisdictions with a confirmed address-zoomable PUBLIC viewer (US, FR-IdF, DE, NL, IE, AT, ES, BE-Brussels, CH [Swiss Lr], UK-England [road+rail], DK, EE, CZ, SI, HU, HR) + the wind statutes (DK/DE/UK/NL/FR/IE/SE/FI/PL + US-WI/OR + AU-SA/VIC — statute values citable as fact, some permalinks flagged for liveness); MEDIUM for the END-mandated jurisdictions where the data exists but only via geoportal/WMS/open-data/per-agglomeration PDFs (PT, LU, IT, MT, CY, PL, LT, LV, SK, RO, BG, GR, NO, SE, FI, IS [road-only viewer + 2025 agency reorg], BE-Flanders/Wallonia) + the per-airport aircraft systems (CA NEF, AU ANEF, NZ NZS 6805, UK-aircraft) + the *absence* findings for MENA/GCC/LatAm/Caribbean; LOW / 🔴 honest for the non-END microstates (AD/MC/SM/LI), the Crown Dependencies + FO/GL, the Western Balkans (RS/ME/BA/MK/AL), the Caucasus + Central Asia (GE/AM/AZ/KZ/UZ), and the entire non-EU/non-US/non-UK tail (most of APAC, South Asia, Africa, the Pacific) — these are reported as a structural contrast (OSM-proximity + WHO calibration + request-operator-contours), never slot-filled with an invented viewer or dB band. **Last verified**: 2026-06-13 (HU operator and RO agency (ANMAP) corrected 2026-09-18 per zajterkepek.hu + anmap.gov.ro). **Pairs strongly with**: - `--traffic` — the parent; emits the count-derived ROAD-noise verdict (🟢🟡🟠🔴). This extension adds the rail + air + wind acoustic-map bands and the acoustic upgrade for road. One combined noise surface. - `--amenities` — the OSM Overpass proximity engine that powers the entire 🔴 honest tail (airport/rail/major-road/wind-farm polylines → distance → WHO directional verdict). - `--risks` — one-line cross-ref only: wind-turbine limit-exceedance and aircraft night-noise are arguably technological-hazard, but the dominant artefact (Lden/Lnight transport contour) is acoustically continuous with the road noise `--traffic` already owns, so `--traffic` is the home. - `--climate` — storm-season airport/rail disruption + grid events are a separate surface; cross-reference where a hurricane-exposed island airport drives both. **Methodology note**: researched via 5 region/topic agents (Western+Southern Europe+UK+microstates viewers; Nordics+Baltics+CEE+SE-Europe viewers; non-EU anglosphere + the aircraft channel; wind-turbine statutes + dB standards; WHO/CNOSSOS calibration backbone) + an independent liveness+correctness audit that GET-verified the public viewer URLs and caught several fabrication-adjacent corrections before shipping: UK Extrium **excludes aircraft** (kept as a load-bearing flag); the DE "34. BImSchV / Sept-2024 wind rule" is a **conflation** (34. BImSchV = noise-mapping ordinance, not the wind-emission limit — wind flows from TA Lärm + 4. BImSchV); FI wind = **45/40** not the prompt's guessed 40/35; NL 47/41 survive only as **temporary Bal §4.30a** rules post-Nevele; DK wind PDF URL corrected to the `urbm0xut` path; UBA app path is `gis.uba.de/maps/resources/apps/laermkartierung` (bare `/website/laerm/` 404s); BTS live host is `maps.dot.gov/BTS/...`; CH publishes Swiss **Lr (LSV/OPB), not EU Lden** (bands not comparable); the WHO **45 Lden wind** figure flagged for re-quote from the full 2018 PDF; NZ ANB/OCB 65/55 dB Ldn is SECONDARY (Environment Guide, standard paywalled). Anti-hallucination posture: every strategic noise map is reported at **map-band granularity with a `(4 m strategic-noise-map contour — verify on visit)` tag**, never as a parcel-precise dB; wind dB *limits* are statute values cited as fact while per-address exposure is flagged as a modelled prognosis; where no national strategic noise map could be confirmed the jurisdiction is marked 🔴 with an OSM-proximity + WHO-calibration + request-operator-contours path rather than a guessed portal URL or dB band; orientation-only viewers (NL Atlas) and bot-blocked-but-live pages (BTS, TfNSW) are flagged honestly, and Swiss Lr is kept metric-separate from EU/WHO Lden so it is never mistranslated.
