Plasmapanel®
Intelligent Sound Control for Demanding 3-D Environments
Plasmapanel is a next-generation active sound control system, delivering breakthrough low-frequency and broadband noise reduction across diverse environments. Powered by patented plasmacoustic technology and AI-enabled real-time processing, it combines high performance with an ultra-slim, lightweight, sustainable, and adaptable design.
Plasmapanel is designed for applications where traditional passive noise reduction and conventional active noise cancelling fall short, excelling in complex 3-D environments such as ventilation across multiple market verticals and cabin interiors. Whether installed in isolation or deployed in scalable formats, Plasmapanel enables precise, programmable sound management without compromising weight, space, sustainability, or aesthetics.
Breakthrough Plasma-Based Technology
At the core of Plasmapanel is a plasma electrode that creates an ionized gas layer using corona discharge. This ionized field is precisely modulated to generate pressure waves in real time, eliminating delays typically caused by mass or mechanical compliance. As a result, the panel functions as a responsive, solid-state sound source for active sound control. Unlike conventional porous absorbers or traditional active noise cancellation systems, the Sonexos plasma-based approach enables deep-subwavelength, ultrawide-bandwidth control—including efficient attenuation of low-frequency noise in 3-D spaces—all without moving parts.
AI-Enabled Acoustic Adaptation
Plasmapanel continuously monitors its acoustic surroundings through embedded microphones and responds in real time, powered by AI-enabled software. The system intelligently optimises performance across absorption, cancellation, and redirection modes, adjusting automatically as the acoustic environment evolves. Whether adapting to changes in airflow, temperature, or mechanical load, Plasmapanel delivers consistently optimal results—even in dynamic settings such as ventilation systems, vehicle cabins, and domestic appliances like rangehoods.
Engineered for Seamless Integration
With a profile thinner than 30 mm and weight under 8 kg/m², Plasmapanel is easily installed into ducts, ceilings, or appliance structures where space is limited. It supports custom dimensions and curved or non-standard shapes, ensuring precise integration into architectural, industrial, and OEM designs. Setup and updates are straightforward via standard Ethernet and USB connections, and whether used as a single smart surface or part of a connected array, Plasmapanel delivers unmatched versatility in noise-critical applications.
