Eight East Hesse towns wired 67 sensors to track real noise — and found levels above WHO recommendations at just under 90% of points, evidence now aimed at Deutsche Bahn's own simulations for a new high-speed line.

LaermLAB has installed 67 noise and environmental sensors across eight East Hesse municipalities since 2024, at points the Technische Hochschule Mittelhessen identified as noise hotspots along the existing railway, federal roads and motorways; some stations also count vehicles. The measured sound levels are meant to be compared with, or fed into, Deutsche Bahn's simulation calculations for the planned Fulda-Gerstungen high-speed line, and the research team is developing AI to tell reliably whether the noise at a station comes mainly from rail or from road.
📊 Impact
At just under 90% of the network's measurement points, noise levels exceed WHO recommendations by day or by night, and at some houses the readings are up to 20 dB above the WHO recommendation — interim results presented by the THM research team and reported in March 2026. In one garden on the project the researchers regularly measure more than 65 dB; the lead researcher notes that a rise of three decibels counts as a doubling of sound pressure.
🎓 Lesson
The measurements are precise and they trigger nothing. Germany gives no legal right to noise protection along existing roads and railways — limits bind only for new construction or substantial change — and those limits follow the federal immission-control law, roughly 59 dB by day and 49 dB at night in residential areas, not the WHO recommendations this project measures against. So the 90% finding is not a breach of anything; its value is as evidence inside the planning process for a line that does not exist yet. That is also why the AI matters more than it sounds: separating rail noise from road noise is what lets a municipality argue with a railway rather than with a total.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
