Sound Therapy using Binaural Beats for Autism on EEG signals : A Review

The last decade has seen a rise in diagnosis of neurodivergent disorders. Studies have
shown that the global prevalence of Autism has risen to 1 in 100 individuals (up from 62 a
decade ago). Binaural beats have shown promise in modulating brainwave activity and are
being explored as a potential therapeutic intervention for various neurological conditions.
This paper investigates the application of sound therapy using binaural beats to enhance
cognitive and emotional responses in individuals with Autism Spectrum Disorder (ASD).
Electroencephalogram (EEG) signals were collected across multiple papers to analyze the
effects of binaural beat stimulation on brainwave synchronization and neural activity
patterns. The results indicate that specific frequencies of binaural beats can induce
relaxation, improve focus, and potentially reduce anxiety levels in individuals with ASD.
Our findings suggest that sound therapy could be a non-invasive, complementary approach
to managing ASD symptoms, with measurable impacts on EEG signals. Further research is
necessary to optimize the parameters of binaural beats for personalized therapy in ASD
interventions.
