Investment Highlights
Noizend is a pioneering Australian technology company dedicated to reducing noise with innovative Physics AI Climate Tech to reduce excessive low-frequency noise.
One market is Data Centres. This is a hot topic with many applications being delayed due to noise. The problem is the constant low-frequency hum. Class actions against xAI (part of SpaceX) and Microsoft have started in the USA against their data centres for noise. This is a major global problem.
Another market is Battery Energy Storage Systems (BESS). Grid Energy BESS are noisy up to 90 dB (like a lawn mower). The main problem is low-frequency noise which is hard to stop and affects local residents. BESS noise is already cancelling or delaying BESS DA approvals.
Noise is a climate problem because:
NOISE BLOCKS CLIMATE INFRASTRUCTURE:
Energy transition developments are rejected, delayed, or constrained due to noise.
SITING CONSTRAINTS INCREASE EMISSIONS:
Urban fringe developments need more transmission, cooling and infrastructure.
NOISE ERODES SOCIAL LICENCE:
Complaints, political pressure and regulatory friction that slows net‑zero deployment.
CLIMATE TECH NEEDS PROXIMITY:
Fast decarbonisation requires BESS near load centres, EV charging hubs and substations.
Company Overview
Noizend is solving chronic low frequency noise problems in the urban environment
Have assembled a multi-disciplinary and multi-company development team headed by Dr Zhao of the University of Technology Sydney
UTS has a designated specialised Centre for Audio, Acoustics and Vibration in Sydney, Australia
Has been approved to join NVIDIA’s inception program for start-ups. Premier virtual accelerator for cutting-edge AI startups that are revolutionising industries
Noizend is solving chronic low-frequency noise problems in the urban environment.
George Tulloch our CTO has been awarded a National Industry Ph.D. grant at UTS. His research will focus on developing physics-informed digital models that can predict and analyse environmental noise from BESS.
Grants from the NSW Government, the City of Sydney Council and access to free software from US Autodesk. Noizend has joined NVIDIA’s inception program for startups.
The main business benefits for BESS energy companies include:
- Reduced noise complaints.
- Increased operational capacity when noise level is controlled.
- Lower maintenance.
- Faster permitting and more site selection opportunities.
It is a rare opportunity to help save the planet whilst accessing a huge global market.
The United Nations listed excessive noise in cities as part of the 3 Planetary Crisis in 2022.
Noizend Acoustic Simulation Software
Noizend has developed the demonstration software in a digital model of the UTS Centre for Audio, Acoustics and Vibration laboratory showing the impact of the use of physics informed neural networks (i.e. AI for physics) showing the noise reduction effects of active noise control working in various locations at low-frequencies.

Products & Services being Developed
Noizend product is called the Noizend Shield. The software will primarily analyse noise and generate multi-channel anti-noise waves. Noizend Shield is an Internet of Things connected system of sensors, speakers and edge processors.
Noizend has access to NVIDIA's cloud-based services to create digital twin models of specific indoor spaces, such as live music venues, factories or warehouses.
Business model is upfront sales revenues and monthly subscription fees – an extraordinary business model.
How It Works
Microphone array: The first step in the multi-channel active noise control (“MANC”) system involves placing an array of microphones around the noise producing equipment or sound source.
Signal processing: The core of the MANC system relies on advanced digital signal processing techniques.
Secondary noise sources: In response to the processed noise data, the system activates secondary noise sources (such as speakers) that are strategically placed around the noise source.
Noise cancellation: The anti-noise signals emitted by the secondary sources combine with the original noise waves, effectively cancelling out the noise through a process called destructive interference.
Feedback control: To ensure optimal performance, the MANC system in the Noizend Shield constantly monitors and adjusts its parameters.
Customisable solutions: The MANC system will be designed to adapt to different types and sizes of noise-producing sources, offering a versatile solution for a wide range of applications.
