Impact of Hearing Aid Processing Delay on Stop Consonant Voicing Perception in Open Fittings

By: Petri Korhonen, Christopher Slugocki, Francis Kuk and Heidi Peeters

Published in American Journal of Audiology

This peer-reviewed research article shows that hearing aid delay affects the perception of consonants. For a sample of 19 listeners with mild-to-moderate hearing loss, the boundary between the consonants /d/ and /t/ was shifted when hearing aid delay was longer compared to no delay or ultra-low delay. In addition, the consonant perception became less certain when the hearing aid delay was longer. This suggests that users with mild and moderate hearing losses may benefit from lower hearing aid delay as implemented in the Widex PureSound™ program with its 0.5 ms ZeroDelay™ technology.

Smart Directional Design

Smart directional design

By: Jennifer Weber & Eric Branda

Published on audiologyline.com, July 15, 2024

This study from the University of Northern Colorado shows the beneficial effect of the Widex SmartRIC design on performance on the Hearing In Noise Test (HINT). The improved microphone angle of the SmartRIC gives an average advantage of more than 1.5 dB for speech understanding in noise, compared to a RIC with a more standard angle. This confirms previous studies showing the improved microphone angle and the associated improvement for speech in noise with the SmartRIC.

The Importance of Natural Sound for Hearing Aid Users and Clinicians

The Importance of natural sound for hearing aid users and clinicians

By Jan Ziegler, Laura Winther Balling & Dana Helmink

Published on HearingReview, June 12, 2024

Hearing aid manufacturers often talk about natural sound without specifying what makes sound natural and precisely how that helps hearing aid users. This article details a range of parameters for hearing care professionals to consider when natural sound is important for the user. Extensive survey data show how these parameters affect users in their acclimatization and life with hearing aids, and hearing care professionals in their clinical practice.

Forms Influence Functions: Microphone Angle and Speech-in-Noise Performance

By Francis Kuk, Christopher Slugocki, Petri Korhonen and Heidi Peeters

Published on The HearingReview, March 13, 2024

This study shows how the more horizontal angle between the microphones on the Widex SmartRIC results in improved performance on the Hearing In Noise Test (HINT). The article explains the theoretical connection between microphone angle and the function of directional microphones and then presents results that show how this affects speech recognition performance for 15 participants with moderate to severe hearing loss.

Impact of a combination sound therapy on tinnitus distress: an exploratory one-year longitudinal study

by Dina Lelic, Sueli Caporali, Daniel Parker, Jakob Nielsen and Laura Winther Balling

Published on Frontiers, March 5, 2024

The study explores the effects of Widex Zen therapy on tinnitus-related distress. Twenty participants with mild to moderate tinnitus distress were fitted with MOMENT 440 hearing aids that included three sound therapy sounds. The therapy sounds were selected by participants from the available Widex SoundRelax and Zen sounds that consisted of fractal music, nature sounds, and combinations of the two. Over the course of twelve months, participants reported reduced tinnitus-related distress as measured on tinnitus handicap inventory (THI), tinnitus functional index (TFI), as well as tinnitus awareness and annoyance.  The improvement plateaued at four months after device fitting and was sustained over the whole study period. Notably, the improvement was related to daily hours of Zen therapy use, but not to amplification-only or overall device use. This suggests that Zen therapy plays a pivotal role in alleviating tinnitus-related distress.

The Widex Sound Philosophy: A Global Perspective on Natural Sound, Innovative Technology, and User Satisfaction

By: Jan Ziegler, Laura Winther Balling, Dana Helmink and André Marcoux

WidexPress 53

This paper explains the principles of the Widex sound philosophy and shows how they translate into user benefits, based on survey data from almost 4,000 hearing aid users. The results of the survey show high satisfaction with the sound quality and the naturalness of the sound. Additionally, the acclimatization to Widex hearing aids stands out, both with high ratings and when compared to hearing aids from other brands that the respondents have worn. Looking more broadly, respondents indicate that their Widex hearing aids have changed communication, social interaction and quality of life for the better. Finally, the overwhelming majority of respondents would recommend Widex to friends and family and request Widex hearing aids next time they need an upgrade. Together, these results show the positive effects of the Widex sound philosophy on both narrowly sound-related parameters and in users’ lives more broadly.
