The effect of noise on listening effort in children as measured using different methods: a systematic review and meta-analyses.

purposeListening effort increases as background noise levels rise, affecting both children and adults. Understanding the impact of increased listening effort and identifying effective methods to estimate it in children is crucial, as higher listening effort can hinder learning. This systematic review and meta-analysis examined the effects of noise on listening effort, as measured using various methods, in children aged 5 to 13 years with normal hearing.

methodsFour scientific databases, PubMed, Scopus, Cochrane Library, and Web of Science, were searched to retrieve 23 eligible articles. The methodological quality of the studies was assessed using Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies. Meta-analysis was performed according to different methods of listening effort [behavioral (single-task paradigm and dual-task paradigm), subjective ratings, and physiological (pupillometry)].

resultsSingle-task paradigm and subjective ratings showed a medium effect of noise on listening effort, which was significant. Dual-task paradigm and pupillometry did not show statistically significant effects of noise on listening effort. Further, speech perception tasks show a greater effect of noise on listening effort as compared to listening comprehension.

conclusionsSingle-task paradigm and subjective rating methods revealed the negative effect of noise on listening effort during spoken language processing in children between 5-13 years of age. Thus, a combination of these two methods might provide useful information regarding the effect of noise on this population. The heterogeneity in the findings could be due to the multidimensional nature of listening effort and lack of construct validity of the methods used to assess listening effort.
