OticonNext: A Nexus for Innovation and Professional Development

OticonNext represented a significant industry forum, bringing together key stakeholders to explore the future of hearing technology. The atmosphere was charged with enthusiasm as HCPs engaged with Oticon’s leadership and R&D teams. The setting itself, a configurable space that transformed into a large ballroom for plenary sessions, inadvertently highlighted a common challenge for individuals with hearing loss: reverberation significantly increases listening effort. This real-world scenario underscored the immediate relevance of technologies like Auracast, which Oticon has championed. An Auracast stream was actively deployed during the plenary, demonstrating its value in improving accessibility in acoustically challenging environments. Breakout sessions provided hands-on training for HCPs on utilizing the Oticon Companion app to tune Auracast channels, customize listening experiences, and effectively communicate these benefits to their patients. The growing proliferation of Auracast-enabled venues and devices suggests a rapidly expanding ecosystem for this technology, promising enhanced accessibility for a broad user base.

The Oticon Reveal: A New Paradigm in Hearing Performance

At the heart of the Oticon Reveal launch is a profound shift in hearing aid philosophy, moving beyond mere amplification to a more sophisticated, brain-centric approach. Michael Lamberson, President of Oticon USA, and Thomas Behrens, Vice President of Hearing Aid Audiology, detailed the core innovations during an exclusive interview. They emphasized that the Reveal is not simply an incremental upgrade but represents a fundamentally different approach to sound processing, distinguishing it significantly from its predecessor, the Oticon Intent.

"When I learned about the advances that the R&D team had been making in algorithms, and then separating speech and contextual sounds, which is part of why we have the Dual AI, and building those algorithms and kind of putting them together for the brain – that was kind of the big insight for me, that this is something that has never been done before," stated Michael Lamberson. He further clarified, "I don’t view it, to me at least, as like a better version of Intent. It’s like the best of all the technologies and learnings that we’ve had over the years."

Dual AI: Harmonizing Speech and Contextual Sounds

The cornerstone of the Reveal’s innovation is its Dual AI system, a sophisticated architecture powered by two independent Deep Neural Networks (DNNs) running on a single main hearing aid signal processing chip. This integrated design allows the two AIs to "know what each other is doing," fostering a collaborative processing environment that significantly enhances sound quality and user experience.

  • Speech AI: This network is meticulously trained to identify and precisely track speech across all frequencies, even in complex listening environments. It works to clean up speech signals, delivering crystal-clear dialogue.
  • Context AI: Receiving information from the Speech AI, the Context AI then intelligently sets the appropriate level for contextual sounds while further reducing residual background noise.

This dual-pronged approach aims to achieve a natural balance between speech clarity and environmental awareness. Oticon’s "BrainHearing" philosophy posits that the brain needs access to a rich soundscape—a mixture of speech and surrounding sounds—to function optimally and make sense of its environment. Depriving the brain of these contextual cues, as might happen with overly aggressive noise suppression, can hinder its natural processing abilities.

Thomas Behrens elaborated on this, contrasting Oticon’s approach with the concept of creating a "sound bubble" that isolates the listener from all background noise. "If you really take it all away, you deprive the brain of something super important, which it really needs," Behrens explained. "The way we make sense of sound, the brain is built from these libraries of sounds that are mixtures of speech and surrounding sounds. So that’s what the brain is used to recognizing. We want the brain to continue to have access to that typical type of sound, which makes it better and faster at recognizing sound." This perspective is supported by independent research and Oticon’s internal studies, suggesting that while some reduction of distracting noise is beneficial, complete isolation can be detrimental to cognitive processing.

The system is designed for fully automatic operation, adapting continuously to varying soundscapes, noise levels, and the number of speakers without requiring manual intervention from the user. For specific edge cases or unique listening needs, clinicians can utilize special purpose programs within the fitting software, but the automatic program is engineered to cover 95-99% of daily listening situations.

Addressing Real-World Listening Challenges

The Oticon Reveal’s intelligent sound processing is particularly impactful in challenging environments. The device provides 360-degree access to sounds, while strategically manipulating certain directions to create contrast, lowering the level of noisy locations in the surroundings to make other sounds more available.

  • Noisy Restaurants: The system aims to layer sounds, allowing the brain to select what to focus on. While acknowledging that extreme situations (like a very loud, close-proximity conversation in a Parisian café) remain challenging, the Reveal makes significant strides in improving speech understanding amidst general restaurant din.
  • Music Appreciation: Recognizing the dual nature of music in a user’s life (primary focus vs. background), the Reveal offers both an adaptive automatic program and a dedicated music program. The music program provides more linear, balanced settings for pure listening appreciation, preferred by individuals like the interviewer who mix sound at church. In automatic mode, the device adapts continuously; when speech is detected, it enhances clarity, and when no speech is present, it provides general amplification, allowing the brain to engage with the music as desired. This flexibility helps navigate complex social settings where music and conversation intertwine.

The Cognitive Impact: Reducing Listening Effort and Fatigue

A significant focus of Oticon’s development has been on mitigating listening effort and cognitive fatigue, common complaints among hearing aid users. By providing the brain with a more organized and complete sound input, the Reveal aims to reduce the mental strain required to understand speech, particularly in noisy or complex environments.

The conversation highlighted anecdotal evidence and ongoing research supporting this benefit. The interviewer recounted a personal experience of significantly reduced fatigue during demanding business trips to China after being fitted with hearing aids. Similarly, Michael Lamberson shared his intention to fit his 86-year-old father, who experiences exhaustion from current hearing aids, with the Reveal, anticipating a re-energizing effect and improved social engagement.

Thomas Behrens further explained, "When we can give the brain all the details of sound, then it’ll start sorting out sound more naturally." This suggests that the Reveal not only clarifies sound but also helps to "re-educate" the brain, leveraging its natural plasticity to sort desired sounds from unwanted ones. Oticon’s research, involving studies on evoked potentials and pupillometry, is actively validating that these technologies provide the brain with better input, allowing it to perform its natural functions more effectively. While these measures are currently in the research phase for direct, real-time feedback, they are instrumental in informing and training the hearing aid’s algorithms.

A compelling, albeit unpublished, UK study was cited, comparing young people using noise-canceling headsets with individuals aged 50 and above. Surprisingly, despite better baseline hearing, the noise-canceling headset users performed poorer on difficult speech-in-noise tasks. This underscores the long-term cognitive consequences of consistently blocking contextual sounds, reinforcing Oticon’s philosophy of preserving environmental cues to maintain brain function crucial for separating speech from noise.

Furthermore, studies cited by Oticon demonstrate that well-fitted hearing aids with effective noise reduction significantly improve memory recall. By freeing up the brain’s cognitive resources from the arduous task of merely understanding words, users can allocate more mental energy to processing, comprehending, and storing information in long-term memory. Brain scans have previously shown the frontal cortex of individuals with hearing loss working overtime just to decipher speech, illustrating the immense cognitive burden that effective hearing aids can alleviate.

Enhanced Connectivity and Auracast Integration

Beyond sound processing, the Oticon Reveal introduces a new, enhanced connectivity platform. This upgrade focuses on improving the underlying hardware—antennas, radios, and wireless protocols—to ensure more stable connections and extended range. The Reveal maintains compatibility with existing protocols such as Made for iPhone (MFi), LE Audio, and Android Stream for Hearing Aids (ASHA), but with significantly improved performance.

The advancements are particularly relevant for individuals leading connected lifestyles, who rely on their hearing aids for hours of online meetings, podcasts, and phone calls. The enhanced stability and range ensure seamless integration into daily digital life. Oticon’s continued support and improvement of Auracast are also highlighted, with executives predicting a rapid proliferation of the technology in public spaces like airports and sports bars within the next few years. This will provide unparalleled accessibility for both hearing aid users and the general public, transforming public audio access. The new platform ensures that the sound quality through these connectivity channels is radically increasing.

Technical Specifications and Global Rollout

The Oticon Reveal is available in a standard Receiver-in-Canal (RIC) style, offered in four different technology levels, and includes a CROS version for individuals with unilateral hearing loss, incorporating all the core Reveal technologies. While a dedicated superpower device update is "100% on the radar," the Reveal RIC model itself boasts a surprisingly high power level and wide fitting range, potentially serving some individuals who previously might have required a superpower device. This is partly attributed to updated feedback prevention mechanisms, which allow for higher amplification without compromising sound quality or introducing feedback.

Key technical specifications include:

  • Battery Life: A full 24 hours of use with 4 hours of streaming, maintaining performance for the typical 4-5 year lifetime of the hearing aid.
  • Durability: IP68 rating, indicating high resistance to dust and water splashes, suitable for daily wear in various conditions.
  • Wind Noise Suppression: A notable 10 dB improvement in wind noise suppression compared to previous devices, allowing users to hear better in windy outdoor environments.
  • Feedback Prevention: Updated algorithms enhance feedback cancellation, contributing to the device’s higher fitting range and overall sound clarity.

The global rollout of the Oticon Reveal is being executed in phases. Many European countries began sales in August, with others, including Canada and additional European markets, scheduled for September and Q4. With regulatory delays being the primary exception, the device is expected to be available globally in the near future.

The Future of Hearing Technology: AI’s Untapped Potential

Looking ahead, both Michael Lamberson and Thomas Behrens expressed immense optimism for the continued impact of Artificial Intelligence and Deep Neural Networks on hearing aid technology. Lamberson likened the current advancements to the monumental leap from analog to digital hearing aids, underscoring the transformative potential.

"I think it’s just going to be deployed more and more," Lamberson predicted. "The algorithms that we use, I’m guessing, are going to get better, more refined. And there’s just going to be improvement that you can just, with AI, the abilities, it’s an awesome tool." He even articulated an inspirational vision: "I absolutely think it’s possible to get back to natural hearing."

Behrens echoed this sentiment, emphasizing that Oticon’s engineers are actively working on "hard problems that people thought were impossible to solve." The company plans to deploy AI on a number of specific hearing-related challenges, anticipating a "big revolution for hearing aid technology over the coming 5 to 10 years." With new technological advancements providing more sophisticated processing capabilities and novel algorithms being implemented, Oticon believes it is "only getting started," promising significant improvements for users grappling with specific listening difficulties. The Oticon Reveal stands as a powerful testament to this ongoing revolution, offering users a more intuitive, less fatiguing, and richer listening experience by harmonizing the digital with the brain’s natural ability to hear.
