Improved signal-to-noise ratio and classroom performance in children with Autism Spectrum Disorder: A systematic review
This paper systematically reviews the literature to determine if improving the signal-to-noise ratio (SNR) improves classroom performance in students with autism spectrum disorder (ASD).
Six databases were searched for the terms acoustics, signal-to-noise ratio, classroom and ASD. Five studies were found that met the selection criteria.
All five studies reported improving the SNR benefitted students with ASD in the classroom. Benefits included improved listening behaviours, increased on-task behaviours, improved speech recognition and reduced listening stress.
The evidence is suggestive that improving the SNR improves classroom performance in students with ASD. Limitations included the small number of studies and limited range of technologies considered. Further research should consider other technologies that could mitigate tactile sensitivities present in some students with ASD.
