Abstract
Hyperacusis is highly prevalent in the autism spectrum disorder (ASD) population. This auditory hypersensitivity can trigger pragmatically atypical reactions that may impact social and academic domains. Objective: The aim of this report is to describe the relationship between decreased sound tolerance disorders and the ASD population. Topics covered: The main topics discussed include (1) assessment and prevalence of hyperacusis in ASD; (2) etiology of hyperacusis in ASD; (3) treatment of hyperacusis in ASD. Conclusions: Knowledge of the assessment and treatment of decreased sound tolerance disorders within the ASD population is growing and changing.
Highlights
Decreased Sound Tolerance Disorders (DSTD) are routinely observed in autism spectrum disorder (ASD)
Hyperacusis is a class of decreased sound tolerance disorders in which a negative or incongruous reaction is triggered from exposure to sounds that are not described as threatening or uncomfortable by a neurotypical individual [1,2,3,4]
They suggested that a value of ULLmin equal to or below 77 dB hearing level (HL) should be taken as indicating the presence of hyperacusis [14]
Summary
Decreased Sound Tolerance Disorders (DSTD) are routinely observed in autism spectrum disorder (ASD). Hyperacusis is a class of decreased sound tolerance disorders in which a negative or incongruous reaction is triggered from exposure to sounds that are not described as threatening or uncomfortable by a neurotypical individual [1,2,3,4]. These reactions are in response to general sounds, rather than specific sounds (such as chewing and sniffling), as would be the case with misophonia [5]. Other theories propose the role of central gain enhancement in hyperacusis and the possibility of hyperacusis to be an indication of problems with the limbic system or auditory pathway [10,11,12]
