About us

Sonexos is a Swiss engineering company specializing in high-performance audio and sound control. We develop and supply advanced solutions for audio enhancement, noise and vibration control to clients in the consumer, transportation, automotive and industrial sectors.

A core innovation is our Plasmapanel technology—an active acoustic solution that achieves broadband sound absorption in enclosed spaces such as vehicle cabins, rooms, offices, ducts, and machinery. Unlike passive treatments that rely on mass or porous materials, Plasmapanel actively absorbs the energy of incident sound waves upon contact, delivering lighter, more space-efficient noise reduction across a wide frequency range.

 

Beyond our R&D capabilities, Sonexos provides strategic advisory services to help clients accelerate innovation in sound and acoustics. Our offerings include product design consultation, acoustic benchmarking, system integration support, and scalable manufacturing guidance—ensuring successful deployment of advanced technologies and long-term differentiation in the marketplace.

By combining deep technical expertise with a pragmatic, system-level approach, Sonexos empowers companies to elevate acoustic performance where it matters most – where sound enhances experience.
