After a hiatus, I’m happy to dust off the clinical research blog. The review this month is Munoz et al (2017) Effective Communication Behavior during Hearing Aid Appointments.
You may find this excerpt interesting: “A striking outcome was the significant reduction in personal speaking time of audiologists following a pre-training workshop. When the speaking time of both patients and audiologists were compared (audiologists dominated during pre-training) both were approximately equal after the workshop. Although speaking time was not explicitly stressed in the workshop, these findings suggest a reduction in audiologist verbal dominance after training, suggesting that the training positively impacted this counseling behavior.”

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.

Since the early 80s, we’ve understood that self-reported hearing loss is highly correlated with feelings of loneliness and inferiority, reduced interest in leisure activities and withdrawal from others. Researchers have only recently started focused investigation toward the influence of hearing aid use on subjective perception of loneliness. In this blog, we review the work of Weinstein and colleagues, who found significant loneliness reduction among a group of new hearing aid wearers.

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 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.

Prolonged, untreated hearing loss has been linked to increased social isolation, decreased brain volume, and range of subjective and objective declines in cognitive abilities. Hearing aids have been shown to beneficially affect some of these traits but a great deal of unknown details remain. A number of active studies aim to answer the question “does hearing aid use slow cognitive decline?”. The work of Deal and colleagues is a valuable step toward finding that answer.

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.

On this month’s blog we review one of last year’s top 5 research articles. Rauterkus and Palmer (2014) asked people to rate characteristics of people wearing a variety of ear-level devices, some of which were hearing aids. Ratings taken today, as compared to those collected decades ago suggest that hearing aid use is carrying less social stigma than it once did.

This month we review a recent study from Souza and Sirow that assessed working memory with several clinically fit hearing aids. The results suggest that aspects of cognitive status may play a role in how patients respond to different hearing aids settings.
This month’s blog reviews a newly published article from Crogan and colleagues*. The authors discussed a project investigating the quality of music perception through hearing aids. Various factors related to the patient and hearing aid signal processing were found to be meaningful. We offer clinical advice relative to optimizing a music listening memory for patients that present themselves as music aficionados.
