The Problem
Deep low-frequency noise is the hardest acoustic challenge. At home it comes from the drone of ventilation and HVAC systems, followed by the rumble of appliances such as rangehoods and dryers, and then in vehicles as engine vibration, road resonance, and airflow noise, all sources that consumers readily notice and remember.
Conventional active noise control, such as in headphones and earbuds, only manages noise at a single point, essentially a one-dimensional problem. In real environments, noise is three-dimensional, diffuse, and dynamic. It intrudes on comfort, undermines premium product experience, and increasingly attracts the attention of regulators concerned with health and environmental impact.
The Breakthrough
Plasmacoustic Platform
Sonexos has developed the world’s first Plasmacoustic Platform, a three-layer architecture that neutralizes low-frequency noise in real 3D environments
Plasmadrive™
The core component that converts cold atmospheric plasma into controllable acoustic pressure.
Plasmacoustic Metalayer®
An AI-enabled control layer that shapes the plasma field to dynamically adapt to acoustic conditions.
Plasmapanel®
A hermetically sealed, product-integrated panel designed for scalable manufacturing.
Market Focus
Where Noise Matters Most.
Our initial focus is on ventilation systems, the most common source of low-frequency noise in homes, workplaces, and vehicles. This means addressing the hum of HVAC units, the rumble of kitchen rangehoods and dryers, and the steady drone of air systems in cars and mass transport.
From there, our technology naturally extends to cabin noise abatement in premium vehicles, commercial buildings, and industrial facilities where air handling is critical.
Looking further ahead, we are evaluating opportunities with prospective partners in aviation, high-speed rail, and defence, environments where compact, reliable low-frequency noise control can transform safety and comfort.
