With the multitude of rehabilitative considerations to be made during follow-up appointments, we often forget to review the valuable data collected through hearing aid data logging. Of interest should be estimated daily wear time, as this can provide valuable insight to a patient’s reliance on the devices. In this review, Solheim and Hickson show discrepancies between logged use time and patient reported use time, pointing toward additional utility in the objectively logged data.

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.

This group is the 2016 Board for the American Academy of Audiology Foundation. Their work and many audiologist and sponsor donations supported $164,000 in research grants and educational programs during 2015. Fund raising is off to an even stronger start in 2016.

Understanding speech in noise poses difficulty for hearing-impaired people of all ages. Even older adults with normal hearing sensitivity demonstrate greater difficulties than their younger, normally hearing counterparts. The work of DeGesst and colleagues documents increases in effortful listening that closely follow the listeners’ age.

Many individuals with hearing loss go without hearing aids, if causal linkage exists between increased risk of cognitive decline or dementia due to untreated hearing loss the implications are of meaningful concern for a large population of older adults. These factors have motivated a swell of interest in relationships among declining hearing ability, cognition, and memory for our aging population.
The reviewed study offers a longitudinal look at changes in screened cognitive ability as a function of self-reported hearing status.

In this study, we evaluated four wireless remote microphones that each use a different wireless audio transmission protocol. Results were equivalent across the four systems, indicating that these remote microphones offer similar benefits to those associated with FM remote microphones.

Recent work out of Linkoping, Sweden suggests that new hearing aid wearers experience greater cognitive demands when listening. Over time they adapt to better resolve new auditory cues, decreasing the effort required for listening.

A number of studies have suggested that activating digital noise reduction in hearing aids may improve performance on tasks that are associated with cognitive capacity. This change in performance is attributed to a reduction in effort required for effective listening. This study from Desjardins and Doherty is one of the first to reveal these effects in a sample of participants with hearing loss.
