What Are Potential Treatments for Hyperacusis?

Discussion Hearing is functional in human fetuses at approximately 25-27 weeks gestation.. The aural anatomical structures are developed by ~32 weeks gestation. Hyperacusis does not have a specific definition but in general is an increased sensitivity to sounds (either intensity or loudness). Some authors describe it as “…decreased sound tolerance where there is a negative reaction to the physical characteristics of the sound,” and other authors use “…increased sensitivity to sound in levels that would not trouble a normal individual.” Phonophobia is a true fear of sounds with anticipation causing anxiety at the sight or thought of the object generating the sound. Misophonia is distress caused by certain sounds or patterns of sounds (e.g. chewing, scratching of chalkboards) rather than the sound loudness. Tinnitus can be a ringing or buzzing sound and in general practice means any perceived sound that is not generated externally. Tinnitus usually does not arise to the level of distress but could. A tinnitus review can be found here. Hyperacusis has a reported prevalence of 3.2-17.1% in the general population but is markedly increased in other populations. For example children with autism spectrum disorder and William’s syndrome have an 18-63% and 95% prevalence rate respectively. In one study the commonest age of presentation was 3-4 years but ranged from 1-15 years. It is not uncommon for young children to be sensitive to sounds but ...
