Hearing aid innovator Signia, part of WSA, today introduced Signia Multi-adaptive Xperience (MaX) to the Canadian market. The world’s first multi-dimensional AI hearing aid platform with 4 DNNs powered by Acoustic Intelligence™, helping wearers fully participate in life's most vibrant, noisy moments.

Most hearing aids perform well in one-on-one conversations but struggle to keep up in real-life dynamic settings. That's because they apply the power of AI in only one dimension: noise reduction. That approach can make the world quieter – but at the cost of connection and immersion.

Powered by Acoustic Intelligence™, Signia MaX continuously analyzes multiple dimensions of sound simultaneously – including 1) speech, 2) noise, 3) environmental conditions, and 4) the wearer’s own voice – enabling hearing that adapts to the full listening moment, not just the noise.

“For years, we've helped patients hear better, but the greatest challenge in hearing care has always been helping them fully participate in complex, noisy group conversations. Signia MaX represents a significant step forward, using Acoustic Intelligence to understand speech, noise, and the listening environment as a whole. This new approach to AI-powered hearing care gives us the opportunity to deliver more enhanced listening experiences and greater confidence in the situations that matter most, helping patients stay connected to the people and moments they don't want to miss,” said Michèle Dostaler, Head of Clinical Education at WSA Canada.

Acoustic Intelligence: Four Deep Neural Networks, One Unified Understanding

Acoustic Intelligence unites four task-specific Deep Neural Networks (DNNs) – Speech Detection, Own Voice Detection, Scene Analysis, and Noise Processing – each trained to understand a different dimension of sound while working together as one coordinated system. Unlike traditional hearing aid architectures that primarily apply AI to a single function, Acoustic Intelligence™ continuously shares information across all four deep neural networks, enabling sound processing decisions that account for the complete listening environment in real time.

This multi-dimensional understanding of the soundscape allows Acoustic Intelligence to power the four core features of MaX:

• RealTime Conversation Enhancement^AI – Locates and enhances multiple conversation partners in dynamic group conversation. It now processes 75% more data points per second compared to Signia IX.
• Own Voice Processing^AI – Provides immediate, accurate own voice recognition without any in-clinic calibration.
• Ambient Scene Adaptation^AI – Moves beyond traditional scene classification and fixed listening programs to continuously analyze and adapt to multiple environmental characteristics.
• Dynamic Noise Control^AI – Understands what noise is present, where it comes from, and whether the wearer is in conversation – adjusting noise reduction appropriately.

By combining this integrated AI processing with Signia’s ultra-fast ear-to-ear technology, the MaX platform also helps ensure both hearing aids remain continuously synchronized as the listening environment changes. This allows Acoustic Intelligence™ to operate as a coordinated binaural system, supporting faster, more consistent sound processing decisions across both ears in real time.

The platform is powered by the new Signia MaX chip which delivers 54x more processing power than previous generations, 50% greater energy efficiency for all-day, always-on performance, and 2x the memory required for continuous real-time analysis.

Signia Pure C&G MaX: Designed for Every Day

The Pure C&G MaX receiver-in-canal (RIC) hearing aid will be the first hearing aid available on the Signia MaX platform. Available in eight colour options, the Pure C&G MaX is designed to suit a range of wearers’ lifestyles.

It ships with a pocket-size portable charger that stores up to four full charges, provides a full charge in four hours, and delivers up to six hours of runtime from just 30 minutes of charging.

It also boasts OneConnect Technology – supporting Bluetooth^® Classic, LE Audio, Telecoil and Auracast™ connectivity, giving HCPs one platform that meets every patient's connectivity needs.

“In the clinic, every patient has unique communication needs, but they all expect technology to work seamlessly with their daily lives. What we appreciate about Pure C&G MaX is that its broad connectivity options allow us to focus on the patient's hearing goals and listening challenges, rather than spending time finding the right technology match. Having a device that supports today's connectivity needs while being ready for future innovations gives both clinicians and patients added confidence in their investment,” adds Dostaler.

Auracast: Ready for shared and public audio experiences as they roll out. Full Auracast functionality will be enabled via a firmware update delivered through the Signia One app by March 2027.
