Anecdotally, wearers of Widex ZeroDelay technology report that sounds are perceived as “more three-dimensional,” “having more layers,” and “spacious.” This article explores the effects of reverberation on hearing aid listening and offers an explanation about why wearers may have made such observations.
A broader appreciation for the unique difficulties faced by many of our patients relative to speech understanding in noise and working memory is critical to tailoring individualized interventions that help them realize the full potential of their residual hearing. At present, the Repeat and Recall Test (RRT) shows promise as an efficient, audiology-based integrative tool of speech-in-noise assessment that includes a more complete understanding of a listener’s experience in a loud speech background at various realistic SNRs.
In the past 15 years, research has suggested that people with hearing loss might benefit from either fast or slow compression depending on their cognitive status. This article reviews the concept of compressor speed and its possible relationship to cognitive capacity and also looks at how the Variable Speed Compressor (VSC) used in the BEYOND hearing aid may allow optimal speech understanding for people with all cognitive backgrounds.
Although vent diameter decreases the directivity index of a directional hearing aid, a significant directional and noise reduction benefit is still available even with an open fitting. This study suggests that open fittings appear to be most beneficial (or least compromising) for people with milder hearing losses, or precipitous loss with normal low-frequency hearing where SNR loss may be milder.

Current thinking on managing a low frequency hearing loss supports the use of broadband, multichannel WDRC hearing aids. In this way, both the low frequency and mid-to-high frequency cochlear fibers can be stimulated. This article examines the issues and decisions involved when fitting reverse-slope losses.
