In 2013, we reviewed an article from Dr. Ben Hornsby in which he reported on an initial foray into the fatiguing effects of listening to speech while managing a cognitively challenging secondary task (read here). The outcomes of his investigation suggested that use of hearing aids may reduce fatiguing effects of completing that secondary task. In more recent work, Drs Hornsby and Kipp assessed utility of standardized measures of fatigue among a large group of subjects with hearing loss.

While speech is arguably the most important sound that listeners encounter on a daily basis, the perception of other sounds should be taken into consideration, including music. In this study, Arehart and her colleagues examined the effect of a variety of signal processing conditions on music quality ratings for normal-hearing and hearing-impaired individuals.

In this month’s blog the three primary goals from a recent study by Keidser and colleagues are reviewed. The authors report on a series of factors that affect benefit from directional microphones in hearing aids. Specifically, they were interested in the effects and interaction of three potential sources of variability: differences in the individual SNR achieved by physical directional benefit, differences in the ability to make use of SNR improvements and variability related to measurement error.

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.
Individual variability in outcomes with directional microphones
Variability in techniques for frequency lowering
Individual variability in aided and unaided acceptable noise levels
Accounting for individual variability in an auditory rehabilitation plan
Individual variability in aided measures of cognitive function
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.
There’s a common assumption, one supported by past research, that older people with hearing loss will have a smaller social network and demonstrate a tendency to avoid difficult listening situations. Drs. Wu and Bentler used a combination of questionnaires and sound level measurements to understand the differences in some social patterns between younger and older people with hearing loss. This month’s post reviews their work.
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.
The Tinnitus Functional Index (TFI) is a new and well validated questionnaire for evaluating tinnitus. If you work with tinnitus patients you should take a close look at the TFI. The source article just won Ear & Hearing’s editor’s award and happens to be this month’s review article. Enjoy.
For those of you who would like to use the TFI. It is now available on a website hosted by Oregon Health & Science University (OHSU). OHSU owns the copyright to the TFI and permission is required by OHSU to use the TFI. The request form takes 3 minutes to complete and allows you access to the TFI form and instructions. You will be able to use the TFI with no fee.TFI Application
Today’s update is the first in a series discussing outcome measures. Dr. Stevens and I decided to start with a review of the SSQ, one of Stuart Gatehouse’s many contributions to audiology. Next month we will review the new Tinnitus Functional Index (TFI).

This month we discuss a new JAAA article from McArdle, Killion, Mennite, and Chisolm. The authors review existing literature and discuss newly collected data that highlight differences in the benefits of unilateral and bilateral hearing aid fitting. This will be the first in a series reviewing research findings that compare outcomes in unilateral and bilateral hearing aid fitting.
