Stop it at the boundary.
Low-frequency noise carries further than any fence, the complaint that stalls approvals, cuts operating hours and sours neighbours. We measure it, predict it and are building the technology to cancel it.
What noise costs an operator.
Planning and consent
Noise objections delay development applications. Defensible evidence keeps your application moving.
Hours and curtailment
Complaints become operating restrictions. Know your footprint before the regulator does.
Licence to operate
Neighbours don't measure decibels; they lose sleep. Fixing the hum protects the relationship.
An acoustic digital twin, built from a short survey.
Measure
A short, synchronised microphone campaign, delivered in days, not months. A full 20–500 Hz map of your noise.
Predict
The system accounts for operations and weather, flagging where the boundary will get loud.
Control
Active cancellation hardware at the loudest edges, aimed by the twin. In development.
The pipeline is the same.
The sound source changes.
BESS and grid
Inverter hum limits where storage can be built. Reducing noise allows for quieter boundaries and BESS being located closer to existing buildings.
Data centres
Chillers and generators run all night. Boundary control builds social license and enables hyperscale.
Infrastructure
Long construction timelines can last for years next to homes. Evidence keeps the labour window open.
Venues
Keep the bass inside the room, protecting operation licences and neighbours.
Noizend Analyse
A short survey becomes a full 20–500 Hz noise map, evidence for a regulator, council or board.
Noizend Predict
Forecasts noise at the boundary before it breaches, so you can act before the complaint.
Noizend Control
Active cancellation at the source, sensors, AI and speakers that cut the hum walls can't stop.
A clear point of view on a stubborn problem.
Measure the invisible
A sparse microphone campaign becomes a full 20–500 Hz map of a site. Physics-informed models fill the gaps between the mics that manual methods leave blank.
Partner, don't replace
Incumbents like CadnaA, SoundPLAN and SiteHive built the field. We automate the modelling step and feed the output straight into the approvals consultants already run.
Cancel at the boundary
The practical place to stop the hum is the edge of the site making it, active cancellation aimed by the digital twin, not blanket treatment of everything inside the fence.
