“…Dawes et al (2014) did not find any changes in P1, N1, or P2 peaks of the cortical response after 12 weeks of hearing aid use. However, Rao et al (2017) found a significant reduction in P3a amplitude in older adults with mild to moderate hearing loss after four weeks of hearing aid use. The differing results between the two studies might be attributed to the cortical measures and methodology employed in the studies; the P3a peak was obtained through an odd ball procedure and is linked to attention; therefore, effects of amplification may be more evident when there is a direct link to cognitive resources within the methodology used.…”

Restoration of sensory input may improve cognitive and neural function

Age-related hearing loss is one of the most prevalent health conditions among the elderly. Hearing loss may lead to social isolation, depression, and cognitive decline in older adults. The mechanistic basis for the association between hearing loss and decreased cognitive function remains unknown as does the potential for improving cognition through hearing rehabilitation. To that end, we asked whether the restoration of sensory input through the use of hearing aids would improve cognitive and auditory neural function. We compared a group of first-time hearing aid users with a hearing-matched control group after a period of six months. The use of hearing aids enhanced working memory performance and increased cortical response amplitudes. Neurophysiologic changes correlated with working memory changes, suggesting a mechanism for decreased cognitive function with hearing loss. These results suggest a neural mechanism for the sensory-cognitive connection and underscore the importance of providing auditory rehabilitation for individuals with age-related hearing loss to improve cognitive and neural function. Our findings of improved cognitive function with hearing aid use may lead to increased adoption of hearing loss remedies.

“…Most likely, this was due to using only one session of training in the present study. One may speculate that by providing several sessions of auditory training when background noise is added to training materials, then auditory training becomes an active training method (i.e., more challenging due to more degradation of the speech signal, see Rao et al, 2017) that subsequently would result in better HINT performance. In their review, however, Henshaw and Ferguson (2013) evaluated the effects of auditory training on aural rehabilitation of people with hearing loss.…”

“…In sentence recognition, however, the current research with regards to the effect of auditory training on subsequent sentence identification in noise is inconclusive. For instance, Levitt et al (2011) and Rao et al (2017), both using ReadMyQuips auditory training program, and Sweetow and Sabes (2006) and Olson et al (2013), using Listening and Communication Enhancement auditory training program, demonstrated the efficiency of auditory training on auditory sentence identification in noise, in hearing-aid users. However, Bock and Abrams (2013) and Abrams et al (2015) reported no effects of auditory training on sentence identification in noise in hearing aid users.…”

The Efficacy of Short-term Gated Audiovisual Speech Training for Improving Auditory Sentence Identification in Noise in Elderly Hearing Aid Users

This study aimed to examine the efficacy and maintenance of short-term (one-session) gated audiovisual speech training for improving auditory sentence identification in noise in experienced elderly hearing-aid users. Twenty-five hearing aid users (16 men and 9 women), with an average age of 70.8 years, were randomly divided into an experimental (audiovisual training, n = 14) and a control (auditory training, n = 11) group. Participants underwent gated speech identification tasks comprising Swedish consonants and words presented at 65 dB sound pressure level with a 0 dB signal-to-noise ratio (steady-state broadband noise), in audiovisual or auditory-only training conditions. The Hearing-in-Noise Test was employed to measure participants’ auditory sentence identification in noise before the training (pre-test), promptly after training (post-test), and 1 month after training (one-month follow-up). The results showed that audiovisual training improved auditory sentence identification in noise promptly after the training (post-test vs. pre-test scores); furthermore, this improvement was maintained 1 month after the training (one-month follow-up vs. pre-test scores). Such improvement was not observed in the control group, neither promptly after the training nor at the one-month follow-up. However, no significant between-groups difference nor an interaction between groups and session was observed. Conclusion: Audiovisual training may be considered in aural rehabilitation of hearing aid users to improve listening capabilities in noisy conditions. However, the lack of a significant between-groups effect (audiovisual vs. auditory) or an interaction between group and session calls for further research.

“…RMQ is a computerized program designed to improve speech understanding through AV training in the presence of background noise. RMQ training has been shown to improve HA users’ speech-in-noise perception as well as confidence in target detection in auditory selective attention task (Abrams et al, 2015 ; Rao et al, 2017 ).…”

“…A topic of current interest in audiology and aging neuroscience is the benefits and neuromodulatory effects from HA use and auditory training (Pichora-Fuller and Levitt, 2012 ; Anderson et al, 2013 ; Ferguson and Henshaw, 2015 ; Morais et al, 2015 ; Rao et al, 2017 ). Electroencephalography (EEG) studies have shown mixed results at the subcortical (Philibert et al, 2005 ; Dawes et al, 2013 ) and cortical levels (Bertoli et al, 2011 ; Dawes et al, 2014 ).…”

Although audiovisual (AV) training has been shown to improve overall speech perception in hearing-impaired listeners, there has been a lack of direct brain imaging data to help elucidate the neural networks and neural plasticity associated with hearing aid (HA) use and auditory training targeting speechreading. For this purpose, the current clinical case study reports functional magnetic resonance imaging (fMRI) data from two hearing-impaired patients who were first-time HA users. During the study period, both patients used HAs for 8 weeks; only one received a training program named ReadMyQuipsTM (RMQ) targeting speechreading during the second half of the study period for 4 weeks. Identical fMRI tests were administered at pre-fitting and at the end of the 8 weeks. Regions of interest (ROI) including auditory cortex and visual cortex for uni-sensory processing, and superior temporal sulcus (STS) for AV integration, were identified for each person through independent functional localizer task. The results showed experience-dependent changes involving ROIs of auditory cortex, STS and functional connectivity between uni-sensory ROIs and STS from pretest to posttest in both cases. These data provide initial evidence for the malleable experience-driven cortical functionality for AV speech perception in elderly hearing-impaired people and call for further studies with a much larger subject sample and systematic control to fill in the knowledge gap to understand brain plasticity associated with auditory rehabilitation in the aging population.

Neural Correlates of Selective Attention With Hearing Aid Use Followed by ReadMyQuips Auditory Training Program

Abstract: Hearing aid use was associated with a decrement in involuntary attention switch to distractors in the auditory selective attention task. RMQ training led to gains in speech perception in noise and improved listener confidence in the auditory selective attention task.
