PHYSICS AI for Noise

analyses, predicts and controls noise at the boundary of your building or workplace.

Talk to us How it works

The challenge

Some of the most irritating noises are low-frequency, and the hardest to control. Fences and walls don't stop them.

The problem

Low frequency

The world is too noisy

Offensive noise is everywhere, from traffic and rail to aircraft, machinery, music venues, and even data centres. This can disturb your work or private time, your wellbeing and even your sleep.

IMPACT

UN Environment Programme · 2022

Noise pollution is cited as a top environmental risk to health across every age and social group. In Europe alone, long-term exposure to environmental noise each year causes:

24

premature deaths per million people, every year

96

new cases of ischaemic heart disease per million, every year

1%

GDP cost to national budget every year due to noise

What we do

Digital twin · predictive AI

We're developing noise cancelling technology that cuts low-frequency noise at the boundary of your home or workplace.

Acoustic digital twins

We build a live digital twin of a site to predict how low-frequency noise travels, before it becomes a complaint, a delay, or a restriction.

Predictive, IoT-based control

AI-optimised algorithms and IoT active noise control target the low-frequency energy that traditional barriers and earthworks simply can't stop.

Faster, comprehensive assessment

Better noise assessment tools turn slow, manual compliance work into faster, more comprehensive reporting that feeds straight into approvals.

Technology

Noizend Shield

The future of noise cancellation is AI.

Using IoT sensors, AI-driven algorithms and speakers, our Noizend Shield technology is being developed to dynamically cancel low-frequency noise, solving noise problems anywhere from live music venues to industrial and commercial workplaces.

Step 01

Analyse

IoT sensor arrays map the sound field around a site in real time, capturing the low-frequency energy that walls and fences let straight through.

Step 02

Predict

Physics-informed models reconstruct the sound field and forecast how noise propagates, an acoustic digital twin of the actual environment.

Step 03

Control

Phase-matched speakers emit active counter signals, dynamically cancelling disruptive low-frequency noise at the edge of the space.

Noizend Analyse

Measurement-campaign assessment · 20–500 Hz

Place microphones on site for a short survey. Noizend Analyse fills in the gaps, ready to take to a regulator.

Reconstruct the field

A physics-informed model fills the gaps between microphones, mapping dB-SPL per third-octave band across every receptor on the site.

Screen against the limits

Sensitive receiver compliance against the binding noise limits, with the low-frequency penalty applied where the spectrum calls for it.

Report that feeds approvals

A draft assessment report, generated straight from the reconstruction, ready for consultant review and the approvals pathway.

Applications

Noizend today

01 / BESS

Battery energy storage

Isolate inverter, transformer and fan noise so storage can sit closer to homes, increasing efficiency and density on the road to net zero.

02 / Data Centres

Data centres

Reduce chiller, fan and generator noise so data centres can sit closer to the grid and to people, without the low-frequency hum reaching their neighbours.

03 / Traffic
