Preserving the Temporal Envelope in Hearing Aid Processed Sounds

Temporal envelope and temporal fine structure cues are complementary in nature, and both are used by listeners in their communications. Hearing loss, as well as the etiology and configuration of the hearing loss, could affect the relative importance of each cue for the listeners in their appreciation and understanding of daily sounds. This article reviews the importance of cues related to the temporal envelope and presents results of a study that compares the Widex EVOKE system, which is designed in part to preserve and enhance the temporal envelope, with another premium hearing aid.

Beyond Controversies: The Science Behind Central Auditory Processing Disorder

Central auditory processing disorder (CAPD) is a complex and evolving subject, but remains a solid diagnostic entity. While there is some variance in diagnostic criteria across US and European professional association guidelines, this simply reflects the need for additional research with participants with confirmed CAPD. A considerable body of research exists demonstrating the efficiency of individual central auditory tests and central auditory test batteries based on performance of individuals with confirmed CANS lesions, including such lesions in children. Authors Gail Chermak, PhD, Frank Musiek, PhD, and Jeffrey Weihing, PhD, provide information that will assist clinicians in making informed, evidence-based clinical decisions about CAPD.

Compression Speed and Cognition: A Variable Speed Compressor for All

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.
