Patients with higher cognitive function may benefit more from hearing aid features

This month’s review discusses an in-press publication from Dr. Ng and colleagues. The authors documented participants’ cognitive status through a series of tests that exercised working memory. They found that hearing aid features such as digital noise reduction provide mild improvements to information retention: an effect that was more pronounced for participants with higher cognitive function.


Virtual Conference: Individual Variability in Aided Outcomes

Below are a series of links that will direct you to recorded presentations from a recent conference on Individual Variability in Aided Outcomes. The presentations address a broad range of audiologic topics and can be viewed free of charge. There is also an option to view each of these for continuing education units. Enjoy.

Variability in techniques for frequency lowering
Individual variability in aided and unaided acceptable noise levels
Accounting for individual variability in an auditory rehabilitation plan

Adjusting hearing aids for tinnitus relief

Over one quarter of people report that hearing aids alone provide some measure of tinnitus relief. Shekhawat and colleagues propose that mild adjustments to a hearing aids frequency response may increase likelihood of tinnitus relief during a traditional hearing aid fitting. This article review discusses their findings and describes a series of recommendations for adjusting common hearing aid parameters in a manner that may further increase relief from tinnitus during hearing aid use.

Open Access Recordings for Developing Speech Maskers

For those of you involved in hearing research, available online are open access recordings for the development of competing speech maskers. There are 8 male and 8 female talkers, each is reading the English language ‘Rainbow Passage’ at normal conversational effort. The source files are match for RMS level but left unshaped, retaining their original spectra.

2013 Pediatric Amplification Guidelines for Clinical Practice

The American Academy of Audiology has approved the 2013 Clinical Practice Guidelines for Pediatric Amplification. Creation of these guidelines reflects diligent collaboration among 15 experts over three years time. This substantive revision is the first since 2003 and includes updates that reflect the current state of hearing aid technology and clinical knowledge in pediatrics.

Does lip reading take the effort out of speech understanding?

This month we take a look at an ahead-of-print article in Ear & Hearing. The reviewed study out of Vanderbilt used several different approaches to teasing out the relationship between listening effort and any interactions that arise with and with out lip reading cues.

Can hearing aids reduce listening fatigue?

In a recent study out of Vanderbilt University, Dr. Ben Hornsby reports on data from a study of listening fatigue. This publication is particularly interesting as it is one of the first to systematically probe listening fatigue under controlled laboratory conditions using modern techniques associated with effortful listening.


Individual Variability in Aided Outcomes

The current issue of Seminars in Hearing is focused on the topic of individual variability in aided outcomes. Those working in hearing care, both clinical and research, can attest to the fact that individual variability is an inherent component of our daily routine. The example of two patients with identical diagnostics but widely varying hearing aid outcomes is one that characterizes many hearing aid fittings.

As guest editor for the issue I was excited to select this topic and recruit a talented group of authors. These authors are well respected researchers in a variety of areas related to hearing aid outcomes; each brings a unique insight to the topic of individual variability.

Can aided audibility predict pediatric lexical ability?

For this review we picked from our Top 5 articles in 2012. The authors (Stiles, Bentler, and McGregor) investigated predictive relationships between high-frequency hearing loss, aided audibility, and the lexical ability of school-age children.

Top 5 Articles of 2012!

2012 was an impressive year for scientific publication in audiology research and hearing aids. Narrowing the selection to 15 or 20 articles was much easier than selecting 5 articles from that respectable ensemble. After some thought and discussion with several colleagues, here are the top 5 articles published in 2012!
