Autism spectrum disorders are characterised through impaired development in social interaction, communication and repetitive behaviours and interests (American Psychiatric Association, 2013). The condition is heterogeneous, and despite these symptoms being commonly identified with ASD, the extent of these difficulties are unique to the individual (Lord, Cook, Leventhal, & Amaral, 2000). Commonly, children with autism can experience complications in tactile, visual and auditory processing, with over 96% of children with ASD experiencing hypersensitivities in multiple domains. Sensory processing dysfunction is not specifically limited to individuals on the autistic spectrum; however, it does appear to more prevalent within this population when compared to other developmental disabilities (Marco, Hinkley, Hill, & Nagarajan, 2011;Pfeiffer, Koenig, Kinnealey, Sheppard, & Henderson, 2011). Sound sensitivity is an especially poignant and common issue for those with ASD. Research conducted by Greenspan and Wieder in 2000 found that all 200 participants with ASD displayed evidence of auditory processing impairments (Greenspan & Wieder, 1997). These receptive abnormalities can provoke atypical self-regulatory behaviours which may be observed as aggressive or autonomic fear responses such as covering ears, crying and self injury from blows to the ears (Stiegler & Davis, 2010). Unfortunately these profound aversions are reported to be provoked by common environmental sounds (Koegel, Openden, & Koegel, 2004). By avoiding challenging acoustic environments, children with ASD will experience increased isolation and further impairment in natural and social communications.
