Media Release

Understanding speech in background noise (‘speech-in-noise’ problem) is the most pressing need to solve for people with hearing loss. Sonova is now addressing this challenge with the launch of Phonak Audéo Sphere™ Infinio, a unique hearing aid using real-time Artificial Intelligence (AI)¹. Its proprietary AI chip instantly separates clear speech from background noise and allowed users in a clinical study to more than double their speech understanding in noisy environments, compared to current products in the market². In parallel, Sonova is also launching the Phonak Audéo Infinio platform³. This new family of hearing aids marks the Group’s biggest release to date. According to the WHO, hearing loss affects 430 million people worldwide, a number that is expected to rise to 700 million – 1 in every 10 people – by 2050⁴. Unaddressed hearing loss can adversely affect participation in social life⁵ as well as contribute to cognitive decline⁶.

Staefa (Switzerland), August 6, 2024 – Sonova Holding AG (SWX: SOON) today announces the launch of two new platforms under the company’s primary brand, Phonak: Audéo Infinio and Audéo Sphere Infinio, marking a new era of hearing aids built on a real-time AI based technology platform. Audéo Sphere Infinio builds on Sonova’s new and proprietary dual-chip technology. Of the two new chips, one applies real-time AI to sound processing. With this development, Sonova sets new standards for sound quality, connectivity and power management – all critical needs for people with hearing loss – along with helping to improve speech understanding and conversation quality. The new flagship instrument builds on the company’s expertise as well as existing technologies, while now integrating real-time AI sound processing on the hearing device to significantly increase speech intelligibility². Customers can expect the new hearing aids to be available from August this year⁷.
 
Arnd Kaldowski, Sonova’s Group CEO says: “Solving the speech-in-noise problem is the long-standing goal of modern hearing aid development and essential to improving the quality of life of millions of people with hearing loss. While every user would state we have come a long way in the last 10 years, they will say they still can’t understand conversations as well as they would like to, when background noise is present, like in many crowded places, such as public transport or restaurants. We are convinced that with our new technology, we can make a significant difference for people in need.”  

Andi Vonlanthen, Sonova’s Global Head of Research and Development for Hearing Instruments says: “During Sonova’s 77-year history, we have always been focused on addressing the most pressing challenges of people with hearing loss. With the development of our new real-time AI technology, Sonova has made a huge step forward – also in terms of technological ingenuity. To achieve these significant results, you must implement a powerful Deep Neutral Network (DNN) in a hearing aid. This required us to develop a special chip – DEEPSONIC™, our DNN unit, as well as a specific training and testing environment, so we could optimize the chip’s performance. The entire process took many years and a significant investment in technology development. We are excited to see this innovation going to market now.”

About the Phonak Audéo Infinio platform and portfolio

Next to the new hearing instrument, Phonak is also launching the broad Phonak Infinio platform, which is powered by the new ultra-responsive Phonak ERA™ chip. This chip redefines standards for sound quality, power management and connectivity, resulting in reduced listening effort and fatigue⁸ for users, while significantly extending Bluetooth connection reach. The technology includes:

• Sound quality improvements due to the AI in AutoSense OS™ 6.0 automatic operating system and a newly optimized fitting algorithm.⁹ This sets a new industry benchmark for an automated operating system.
• Improved Bluetooth®¹⁰ Classic connectivity, supporting thousands of Bluetooth-compatible devices, including iOS and Android, with a new antenna to deliver up to six times more wireless transmission power compared to previous generations. This enhancement in connection strength and range significantly improves call stability in the hearing aid.
• The Phonak Audéo Infinio portfolio spans:
  • Phonak Audéo™ R Infinio with the Receiver In the Canal (RIC) form-factor for mild to profound hearing loss.
  • Phonak CROS R Infinio, which is a solution for untreatable hearing loss in one ear, and
  • Phonak Virto™ R Infinio: Phonak’s first rechargeable custom hearing aid.

About the Phonak Audéo Sphere Infinio platform

Phonak Audéo Sphere Infinio is the first hearing aid powered by dual-chip AI technology. In addition to the ERA chip, the device also includes DEEPSONIC, a dedicated real-time AI / Deep Neutral Network (AI / DNN) chip from Sonova's proprietary research and development. This has enabled a breakthrough in the long standing goal to provide optimal speech understanding in background noise, addressing the ‘speech-in-noise’ problem.

The dedicated real-time AI / Deep Neutral Network (AI/DNN) DEEPSONIC chip provides the computational architecture optimized for DNNs (Deep Neural Networks) to address the ‘speech-in-noise’ problem. It has 53 times more processing power compared to current hearing aid industry chip technology¹¹,¹², which allows it to instantly separate clear speech from background noise in a fundamentally different way from the AI used in existing hearing instruments¹. The user experiences significantly improved speech understanding and ease of understanding from any direction, allowing people to engage in dynamic group conversations² without needing to constantly move their head.
 
About the value of technology development in the hearing aid industry 

The hearing instruments industry has undergone important technological developments in the last 30 years that have continuously improved user benefit, while also addressing unmet hearing needs. As the global leader, Sonova has played a crucial role in these technological breakthroughs, including: the first directional microphone technology, Bluetooth connectivity, rechargeable instruments and the use of AI for personalized fitting. Real-time AI now promises an even more profound improvement for people affected by hearing loss, as it directly deals with the key challenge: understanding speech in background noise. Its use will pave the way for the next generation of technological advancements in the hearing aids industry. Addressing hearing loss early is important - according to the WHO, unaddressed hearing loss is estimated to pose an annual global cost¹³ of USD 980 billion¹⁴.

¹ Real-time AI means that the AI DNN (Deep Neutral Network) has been trained on sound samples to separate speech from background noise by processing the audio signal in real-time. This approach is fundamentally different from the use of AI for sound or acoustic scene classification, which is used in current hearing aids in the market. The real-time AI signal processing is performed by the DEEPSONIC™ chip, which is included in the Phonak Audéo Sphere Infinio platform together with the Phonak ERA™ chip.
