The main objective of this research work is to provide a tool to prevent the severe hearing sensitivity to patients with Autism Spectrum Disorder (ASD) experience. The key element in our work is to identify commonalities between sounds that bother an ASD patient, and implement a procedure using PC or smartphone as platform - based on those results, which will lead to the prevention of “bothersome” sounds for the ASD sufferer and later to desensitization. To do so, we implemented a first application that evaluates the auditory sound sensitivity of a person, and a second application that determines those factors that are related to hearing sensitivity of the patient, suggest sounds in the preventive process, and proposes use of appropriate sounds in the desensitization process. While the current implementation is a prototype, we are determined to pursue the development at professional level and implemented as very user friendly application, which we hope will become a popular tool used by medical personnel and ASD patients for the identification of an individual’s specific sound sensitivities and his/her desensitization to those sounds.
