Plasmapanel®

At the core of Plasmapanel is a high-voltage electrode array 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 noise 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—all without moving parts.

Plasmapanel constantly senses its acoustic surroundings through embedded microphones and responds in real time using the Sonexos AI-enabled software. This software can intelligently optimise its performance whether in active absorption, cancellation, or redirection modes, adjusting automatically as the acoustic environment evolves.

Whether compensating for changes in airflow, temperature, or mechanical load, Plasmapanel ensures consistently optimal performance—especially in dynamic environments like ventilation systems, vehicle cabins and domestic appliances, such as rangehoods and clothes dryers.

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 and access are limited. The system supports custom dimensions and curved or non-standard geometries, enabling precise integration into architectural, industrial, or OEM product designs.

Ethernet and USB interfaces make configuration and firmware updates straightforward. Whether deployed as a single smart surface or across a networked array, Plasmapanel brings unmatched versatility to noise-critical applications.
