Sonexos

Sonexos is a Swiss engineering company developing advanced technologies and services for audio enhancement and noise and vibration control. Its focus is low-frequency noise, which can be difficult to manage with conventional insulation and passive acoustic materials. The company’s patented Plasmacoustic® platform uses cold atmospheric plasma and adaptive control to actively absorb sound in real-world environments. Its core technologies include Plasmadrive™, which converts plasma into controllable acoustic pressure; the AI-enabled Plasmacoustic Metalayer®, which adapts the plasma field to changing sound conditions; and Plasmapanel®, a product-integrated panel designed for scalable manufacturing.

Sonexos is initially targeting noise from ventilation systems, including HVAC units, rangehoods, dryers, and air-delivery systems. Its solutions are also intended for vehicle cabins, commercial buildings, industrial settings, and other enclosed spaces. Alongside technology development and supply, the company offers strategic advisory services, including product design consultation, acoustic benchmarking, system integration support, and guidance on scalable manufacturing. Sonexos works with clients and product integrators to improve acoustic performance and create quieter, more comfortable experiences.
