Insights
Sound-based interventions show promise for reducing auditory hypersensitivity and improving emotional and behavioral regulation in children. Further high-quality research is needed to confirm these preliminary findings.
Area of Science:
- Pediatric Psychology
- Auditory Processing
- Behavioral Therapy
Background:
- Auditory hypersensitivity is a common challenge in children.
- Effective interventions for auditory hypersensitivity and emotional regulation are needed.
Purpose of the Study:
- To review the evidence for sound-based interventions in children.
- To assess their impact on auditory hypersensitivity and emotional/behavioral regulation.
Main Methods:
- Systematic review of peer-reviewed studies (2010-2023).
- Included studies of any design examining sound-based interventions.
- Searched for interventions reducing auditory hypersensitivity and improving emotion/behavior.
Main Results:
- Eight studies evaluated six distinct sound-based interventions.
- Preliminary evidence suggests improvements in depression, anxiety, and behavioral outcomes.
- Significant heterogeneity observed across studies in design and outcomes.
Conclusions:
- Sound-based interventions demonstrate preliminary effectiveness for auditory sensitivity and emotional/behavioral regulation.
- Higher quality studies, including randomized controlled trials, are required.
- Greater consistency in outcome measures is needed for clearer evidence assessment.
Abstract:
Introduction: The aim of this review was to examine the evidence for sound-based interventions in decreasing auditory hypersensitivity and improving behavioural and emotional regulation among children. Methods: A systematic review was conducted of primary research examining the use of sound-based interventions to reduce auditory hypersensitivity and regulate emotion or behaviour. Studies were eligible if they were published in English in a peer-reviewed journal, from January 2010 to March 2023. Studies of any design were included. Results: A total of 4741 titles were identified in the search. Eight papers were eligible, covering six different sound-based interventions. Preliminary evidence highlights improvements in depression and anxiety symptomatology and improved behavioural outcomes including language, listening, and social behaviours. Heterogeneity was high across studies; they varied widely in sample size, population type, study design, and outcomes measured. Conclusions: There is preliminary evidence for the effectiveness of sound-based interventions in improving auditory sensitivity and emotional and behavioural outcomes. However, there is a need for higher quality studies, including randomised controlled trials, and consistency in outcomes across studies to enable a clearer assessment of the evidence.
