Hotspots at a glance.
Every measuring point live in dB(A) — the map instantly shows where it’s too loud and where everything stays within the limit.
Car-meet scene, outdoor dining, construction site: Smart Noise measures around the clock in dB(A) — against day and night limits per zone, with alerts on violations. Levels only, never audio.
Opens the demo environment — simulated levels, no account needed.
Smart Noise is the sound app in the urbanOS ecosystem: level sensors measure LAeq/LAmax around the clock — turned into hotspot maps, automatic day/night limits, violation alerts and defensible 24h profiles. Objective values instead of complaint ping-pong.
Residents complain, the source denies it, enforcement stands in between — without numbers. Measuring around the clock shows exactly where, when and how loud — so you can act and prove it.
Nightlife, car meets, construction — measured in dB(A) instead of debated. The map shows where it’s really loud.
Limits per zone switch automatically at 10 pm and 6 am — modeled on the TA Lärm, freely adjustable.
Above the limit → alert with place, level and duration. Patrols go out targeted instead of on suspicion.
Without measurement, every complaint stays an anecdote. Smart Noise delivers the night values per measuring point — hour by hour, night by night — and flags violations automatically.
The result: Friday and Saturday, 11 pm–2 am, clearly over the limit. That’s something you can act on — and the measure’s effect is re-measured with the same sensors.
Every value openly shows which sensor and time period it comes from.
From the hotspot map through automatic limits and alerts to the 24h profile — all from the same sensors, no dashboards to build.
Every measuring point live in dB(A) — the map instantly shows where it’s too loud and where everything stays within the limit.
Day and night limits per zone — modeled on the TA Lärm, switched automatically. Set once, done.
Above the limit, the app fires — with place, level and duration. As a list, push or export for enforcement.
24h profiles and weekly patterns show when it’s really loud — Friday and Saturday 11 pm–2 am, not “always”. The basis for every measure.
The sensors measure sound levels — no audio is recorded. Conversations are physically impossible to reconstruct. Privacy without debate.
The same night, read four ways: the hotspot map, the zone groups, the analytics behind them — and the configuration where the limits are set.




Smart Noise measures levels to standard — and never records audio, on principle.
The Milesight WS302 measures energy-equivalent continuous and peak levels in dB(A) — indoors and out, LoRaWAN battery-powered.
Mast, solar panel and mount — measuring points go where the noise is: square, street, parking deck.
No sound is stored or transmitted. Numbers only — privacy by design.

Every urbanOS app inherits the platform underneath it. You never buy an island.
GDPR-compliant, ISO-certified, hosted in Germany. Your city's data stays your city's data.
Standard IoT sensors over LoRaWAN and existing networks. Deployment takes days, not months.
Add or remove apps as your city's needs change. The platform and your data stay in place.
A complete setup for the first hotspot — level sensors, mounting, app and support in one package. Configure the right scope in the urbanOS calculator.
Included in the packageThe open demo runs on simulated levels: hotspot map, day/night limits, violations and 24h profiles. No account — it’s the same app our cities use.
