Less is More – Optimizing the Dynamic Range of Hearing Aid Output
By Petri Korhonen, Francis Kuk, Christopher Slugocki and Heidi Peeters
Hearing aid users often crank up overall volume in noisy settings, only to find that both speech and background noise increase equally - sometimes making speech seem softer. This is due to partial loudness effects, the fact that speech with the same sound pressure level (SPL) will appear louder in quiet and softer in noise. The Widex SpeechEnhancer Pro uses its Hearing Threshold Level Optimizer (HTL Opt) feature to counteract this. By placing the aided noise floor just below the individual wearer’s threshold in noisy frequency bands, HTL Opt enhances perceived speech loudness and clarity without raising the overall gain. This article reports a loudness matching experiment confirms that HTL Opt makes speech in noise appear less reduced in loudness.
Widex Allure: Balanced Focus and Awareness In Real Life
By Laura Winther Balling, Sonie Harris, Fei Leung, Kathy Pineo, Dana Helmink, Bertrand Philippon
Download a summary of the article
The balance between focus and awareness is often reduced to the simple metric of signal-to-noise ratio, but reality is much more complex, with awareness of surroundings often being necessary or desirable. The Widex Allure hearing aids are designed to optimize the balance between the signal that the wearer wants to focus on with appropriate awareness of surroundings. This paper adds to existing laboratory-based evidence on this balance by showing strong real-life ratings of Widex Allure compared to other hearing aids across noisy situations. Additionally, wearers indicate by an overwhelming majority that the awareness of surroundings is better with Allure than with other hearing aids they have had in the past, and show a clear preference for Allure over other hearing aids with respect to both naturalness, sound quality, and speech understanding, all key aspects to the balance between focus and awareness.
New Hearing Aid, New World of Hearing: First-Fit Reactions to Widex Allure
By: Laura Winther Balling, Dana Helmink, Kathy Pineo, Bertrand Philippon, Fei Leung & Sonie Harris
This paper reports a survey that investigated how the many well-documented benefits of Widex Allure™ are perceived in real life, focusing on the first-fit reactions of 57 experienced hearing aid wearers from several markets. The survey shows overwhelmingly positive immediate reactions: Widex Allure is rated as easy to get used to by 91% of respondents and the sound is perceived as immediately likeable, natural and clear by between 80 and 89% of respondents. The fitting experience is smooth, and the satisfaction, both general satisfaction and specifically with sound quality, is high at 81% and 86%, respectively. This positive perception is likely due to a combination of unique innovations on Allure’s W1 chip with legacy features based on the Widex sound philosophy.
The superior sound quality of Widex Allure
By: Laura Winther Balling, Matthias Vormann, Ole Hau, and Steen Rose
The foundation of Widex’ commitment to optimal sound quality is research showing that sound quality is central to a positive hearing aid experience, with effects of sound quality also on users’ mood and well-being. This paper explains the key design choices that support the Widex sound quality and reports two studies demonstrating the superiority of the Widex Allure sound quality over other hearing aids on the market. A sound quality preference was observed for more than 80% of participants in both studies. With significant advances also in fitting, feedback management, speech intelligibility, and noise reduction, Widex Allure represents a comprehensive hearing aid solution that covers listening needs across real-life situations.
Widex Allure: Balancing Feedback Management with Sound Quality
By Laura Winther Balling, Matthias Vormann, Steen Rose, Ole Hau
This two-part study shows how feedback management is much improved on Widex Allure relative to previous platforms, while the sound quality remains superior to that of other leading manufacturers. Importantly, the superior feedback performance is experienced across different distances from the ear, which constitute different ways of changing the feedback path and in that way mimic diverse real-life situations. Similarly, the sound quality advantage is significant across samples, with Allure being preferred by 84% of participants.
Widex Allure: A Better Speech-in-Noise Experience with Balanced Focus and Awareness
By: Laura Winther Balling, Matthias Vormann and Naim Mansour
The Widex Sound Philosophy means always striving to provide the most natural hearing experience. This is especially critical for noise management features that must reduce noise without robbing the sound of its natural quality and leaving users feeling isolated. Widex Allure’s Speech Enhancer Pro is designed to achieve the optimal balance of noise management, speech intelligibility, and natural awareness of surroundings, helping wearers to be fully immersed in their surroundings. This paper reports a study conducted at Hörzentrum Oldenburg on the Allure Speech Enhancer Pro noise reduction compared to the previous Widex platform. Twenty-five experienced hearing aid users with symmetrical sensorineural hearing loss listened to recordings of real-world sound scenes, including a lounge bar, a restaurant, and a train station. Participants compared pairs of recordings and indicated which recording had less noise annoyance and which recording they preferred overall. The Widex Allure hearing aids were significantly preferred over the previous platform for both noise annoyance and general preference across scenes, with 92% of participants having an overall preference for Allure.
Improved Speech Intelligibility in Noise with Ultra-Low Delay
By: Jennifer Weber & Eric Branda
Published on audiologyline.com, March 24, 2025
Widex revolutionized hearing aid processing with the introduction of the ultra-low delay PureSound program on the Moment platform. With the Allure platform, the redesigned PureSound features new advanced processing features. This study from the University of Northern Colorado shows how this results in substantially improved speech intelligibility in noise, while retaining the high sound quality and other well-known benefits of ultra-low delay for hearing aid wearers with mild and moderate hearing losses.
The Effect of Speech-To-Noise Ratios On Hearing Aid Noise Reduction Systems in Realistic Environments
By Petra Herrlin, Naim Mansour, Frederik Nielsen, Karolina Smeds, and Laura Winther Balling
Published on The HearingReview, March 20, 2025
In order to help wearers in real life, hearing aid noise reduction systems need to balance focus on speech with appropriate awareness of the surroundings. This article reports a set of measurements comparing how different hearing aid platforms do this and shows how the new Widex Allure platform responds to the environment in a much more fine-grained manner than other hearing aids. Allure does this by taking into account signal-to-noise ratio, input level, background noise type, and frequency composition, in order to help wearers balance clear speech with natural awareness of the surroundings.
