| 520 3# - SUMMARY, ETC. | |
| Summary, etc | Objectives: To undertake a systematic review of available evidence on<br/>the effect of hearing impairment and hearing aid amplification on listening<br/>effort. Two research questions were addressed: Q1) does hearing<br/>impairment affect listening effort? and Q2) can hearing aid amplification<br/>affect listening effort during speech comprehension?<br/>Design: English language articles were identified through systematic<br/>searches in PubMed, EMBASE, Cinahl, the Cochrane Library, and<br/>PsycINFO from inception to August 2014. References of eligible studies<br/>were checked. The Population, Intervention, Control, Outcomes, and<br/>Study design strategy was used to create inclusion criteria for relevance.<br/>It was not feasible to apply a meta-analysis of the results from comparable<br/>studies. For the articles identified as relevant, a quality rating, based<br/>on the 2011 Grading of Recommendations Assessment, Development,<br/>and Evaluation Working Group guidelines, was carried out to judge the<br/>reliability and confidence of the estimated effects.<br/>Results: The primary search produced 7017 unique hits using the keywords:<br/>hearing aids OR hearing impairment AND listening effort OR<br/>perceptual effort OR ease of listening. Of these, 41 articles fulfilled the<br/>Population, Intervention, Control, Outcomes, and Study design selection<br/>criteria of: experimental work on hearing impairment OR hearing aid<br/>technologies AND listening effort OR fatigue during speech perception.<br/>The methods applied in those articles were categorized into subjective,<br/>behavioral, and physiological assessment of listening effort. For each<br/>study, the statistical analysis addressing research question Q1 and/or Q2<br/>was extracted. In seven articles more than one measure of listening effort<br/>was provided. Evidence relating to Q1 was provided by 21 articles that<br/>reported 41 relevant findings. Evidence relating to Q2 was provided by 27<br/>articles that reported 56 relevant findings. The quality of evidence on both<br/>research questions (Q1 and Q2) was very low, according to the Grading<br/>of Recommendations Assessment, Development, and Evaluation Working<br/>Group guidelines. We tested the statistical evidence across studies with<br/>nonparametric tests. The testing revealed only one consistent effect across<br/>studies, namely that listening effort was higher for hearing-impaired listeners<br/>compared with normal-hearing listeners (Q1) as measured by electroencephalographic<br/>measures. For all other studies, the evidence across<br/>studies failed to reveal consistent effects on listening effort.<br/>Conclusion: In summary, we could only identify scientific evidence from<br/>physiological measurement methods, suggesting that hearing impairment<br/>increases listening effort during speech perception (Q1). There was no<br/>scientific, finding across studies indicating that hearing aid amplification<br/>decreases listening effort (Q2). In general, there were large differences in<br/>the study population, the control groups and conditions, and the outcome<br/>measures applied between the studies included in this review. The results<br/>of this review indicate that published listening effort studies lack consistency,<br/>lack standardization across studies, and have insufficient statistical<br/>power. The findings underline the need for a common conceptual framework<br/>for listening effort to address the current shortcomings. |
