Our markets

Using our unique skills and commercially-informed expertise, we address many of the most challenging problems in sound, delivering solutions that help set our customers apart from their competition.

Industry & Commercial

Exposure to elevated noise levels from operating machinery, HVAC systems, or poor building acoustics presents significant challenges for operators and residents. These conditions affect communication abilities, cause fatigue, and can potentially lead to long-term hearing damage. Such noise issues are not merely inconveniences but serious impediments to productivity, comfort, and safety in manufacturing and workplace environments. The complexity and scale of the problem, particularly involving lower frequency noises, make identifying effective solutions to mitigate noise impact a challenging endeavour.

At Sonexos, we specialise in creating acoustically optimised work and commercial environments by collaborating with leading industrial and architectural acoustic providers. By leveraging advanced technologies for active noise reduction and sound absorption, we commit to delivering safer and more sonically balanced workplaces. Our approach ensures that each project is tailored to meet the specific acoustic needs of the environment, enhancing overall workplace quality and operator well-being.

Consumer

In today’s competitive marketplace, consumer brands have the opportunity to harness a wide array of sophisticated audio technologies to elevate their products’ sonic performance and functionalities. Emerging innovations such as active noise cancellation, artificial intelligence, voice recognition, and spatial auralisation are but a few examples.

When adeptly implemented, these cutting-edge technologies offer a compelling competitive edge, enhancing consumer awareness and affinity towards both the product and the brand. However, it’s worth noting that embracing these technologies also comes with its set of challenges—potential delays and budget overruns in the development phase, elevated bill-of-material costs, and diminished yields during serial production.

At Sonexos, we serve as strategic partners to consumer brands and their integration partners, offering reliable advice and solutions for the design and manufacturing of products distinguished by their advanced audio capabilities. Leveraging our extensive experience—spanning decades—in developing advanced transducers, smart codecs, noise-cancelling headphones, and audio test equipment, we have successfully served leading Original Equipment Manufacturers (OEMs) in delivering products that stand out in their markets.

By collaborating with Sonexos, clients can confidently navigate the complexities of incorporating advanced audio technology, ensuring a harmonious blend of innovation, quality, and operational performance.

Automotive

The automotive industry is undergoing a profound transformation as Original Equipment Manufacturers (OEMs) and their suppliers transition their development focus from internal combustion engine (ICE) vehicles to electric alternatives. Concurrently, advances in digitalisation and automation are enabling designers to rethink the cabin experience. These changes are far more than aesthetic, as they accelerate the adoption of innovative technologies and new cabin concepts.

Sound remains a pivotal aspect of the driving experience, encompassing both the natural sounds generated by the vehicle in motion, such as engine noise, and the audio produced by entertainment systems and functional chimes. Together, these elements create a rich, immersive sound environment for drivers and passengers, shaping the brand’s unique sonic identity.

At Sonexos, we partner with automotive OEMs and tier-one suppliers to navigate the fast-evolving landscape of vehicle sound and audio technologies. Leveraging deep expertise in active noise control, audio tuning, auralisation, and advanced test and measurement techniques, we deliver tailored services and solutions that address complex challenges and capitalize on emerging opportunities. This ensures our clients remain at the forefront of innovation, driving sustainable competitive advantage.

By combining technical proficiency with a sharp understanding of market dynamics, we help clients not only adapt to rapid change but lead it, deploying next-generation audio and sound solutions that shape the future of the automotive industry in this era of innovation-driven transformation.

Mass Transportation

The acoustic environment inside commercial aircraft and high-speed trains can be a significant factor in passenger comfort and well-being. Often, the auditory experience—encompassing both audio programming and voice communication—is compromised by persistent broadband noise. This form of noise pollution can be distracting, uncomfortable, and even fatiguing for passengers.

Such ambient noise emanates from multiple distributed sources. These include the vehicle’s propulsion systems, aerodynamic interactions between airflow and the vehicle’s exterior surface, as well as onboard Heating, Ventilation, and Air Conditioning (HVAC) systems.

Mitigating this issue requires a multifaceted approach. Traditional solutions often employ lightweight insulating materials designed to dampen sound. More innovative strategies include the use of active noise-cancelling (ANC) technology, which can be integrated into headphones or directly into the seats themselves.

At Sonexos, we specialize in partnering with manufacturers of aircraft and high-speed trains, as well as their equipment vendors, to design and implement acoustical solutions. Our objective is not merely to diminish unwanted noise but to create an immersive, high-quality sonic environment for passengers.

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.
