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.


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, beam-forming, voice recognition, and spatial enhancement 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.


A paradigm shift is currently reshaping the automotive industry, as Original Equipment Manufacturers (OEMs) and their primary suppliers transition from internal combustion engine (ICE) vehicles to electrically powered alternatives. Simultaneously, the digitalization and automation of the driver experience are granting designers unprecedented latitude to reinvent the cabin environment. These advancements are not merely cosmetic; they are accelerating the adoption of groundbreaking technologies and novel cabin concepts.

The auditory experience within a vehicle has historically served as a crucial touchpoint between a brand and its consumer base. Beyond the traditional roar of the engine, soundscapes now encompass a range of iconic tones and immersive audio entertainment, taking on an elevated role in the contemporary automotive landscape.

At Sonexos, we specialize in assisting automotive OEMs and their tier-one suppliers as they navigate this intricate landscape, replete with both challenges and burgeoning opportunities in the realm of vehicle audio and acoustics. We offer targeted solutions for the identification, deployment, and mastery of complex technologies designed to confer a tangible and sustainable competitive edge.

Leveraging our unparalleled expertise in active noise cancellation, audio tuning, auralisation, and state-of-the-art test and measurement techniques, we are uniquely positioned to qualify and configure next-generation auditory solutions. Furthermore, we optimize the streamlined integration of these technologies into vehicles, ensuring seamless calibration at scale.

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.

Industry & Commercial

Exposure to elevated noise levels from operating machinery, HVAC or poor building acoustics poses significant challenges for operators and residents alike, impacting not only their ability to communicate but also contributing to fatigue and potentially long-term hearing damage.

The issues associated with noise or poor acoustics are not merely an inconvenience; they constitutes a serious impediment to productivity, comfort and safety in manufacturing and work environments.

Given the complex nature of the issue, especially in relation to the scale of the problem and the lower frequency issues typically involved, identifying practical solutions to alleviate noise impact can be a complicated endeavour.

At Sonexos, we specialise in creating acoustically optimised work and comemrcial environments by collaborating with leading industrial and architectural acoustic suppliers.

Furthermore, through the deployment of state-of-the-art technologies for active noise reduction and sound absorption, we can deliver safer and more sonically balanced workplaces.
