Pediatric Hyperacusis

Children can have hyperacusis.  They often are unable to describe it very well using words, and instead use body or emotional gestures (crying, screaming, hitting, biting) to communicate.  They may also simply try to 'get away'.

 Research shows that about 17-20% of all children with autism or Asperger's or similar conditions  will also have hyperacusis.  Common signs include crying in noisy environments, clasping hands over the ears, fear of noise or noisy objects, self-harm when exposed to loud noise, i.e. vacuum cleaners, and reluctance to participate in noisy or loud activities, i.e. watch parades, birthday parties, musical presentations, etc.  Children free of these conditions also can aquire hyperacusis, particularly following frequent or severe ear infections, head injuries, viruses, or medication adverse reactions, or unknown causes.

 Hyperacusis, sound annoyance, and loudness hypersensitivity in children.


The objective of the present study was to estimate the prevalence of hyperacusis among school-aged children. We define hyperacusis as lowered loudness discomfort levels (LDL) associated with an abnormal annoyance to sounds. We used questionnaires, interviews, and estimates of LDL in a study of 506 children from 5 to 12 years of age from 15 different schools. Participants with LDL in the lowest 5th percentile were classified as having loudness hypersensitivity; an abnormal annoyance to sounds if they responded "yes" to the question "Are you bothered by any kind of sounds or noise?" could describe the sound, and were able to identify at least 10 sounds from a list of 20 as being annoying. Phonophobia was defined as a fear of sound. Children with LDL in the lowest 5th percentile typically had LDLs lower than 90 dB HL; 42% of the participants in this group were bothered by sounds and 3.2% had hyperacusis. Fifty percent of the participants with hyperacusis had tinnitus and mild hearing loss in the left ear was an associated risk factor. Phonophobia was experienced by 9% of the children. It is concluded that hyperacusis in children is prevalent, and should be considered in clinical examinations.

 Many times, it is the subjective observations from parents, teachers, or care givers that is used to support a diagnosis of hyperacusis.  Frequently, primary care physicians find it difficult to diagnose hyperacusis as a primary symtpom and will refer to an ear specialist.

 Since 1997, our clinic has been fitting children with bilateral broadband signal generators, open ear canal styles, or preprogrammed personal listening devices such as MP3 players, in patients as young as four years old.  Our data, collected over 14 years, shows that about 2/3s of the children who try out these devices, benefit signficantly.  Other young children have been helped by using gentle environmental sound sculpting, with fans, fountains, music, nature sounds, and so on, provided at home and at school, to help the children recover or improve their hyperacusis.

 For some children, the sound acts like a masking therapy, removing some of the difficulties with sudden sounds or persistent intruding and irritating noises.  The devices can be soothing and comforting for some children, raising the ambient noise levels which can create a calmer auditory environment.

 All children who are eligible for the use of these devices should be examined thoroughly by a medical specialist (ENT or otolaryngologist) and audiologist first.   There is a great list of qualified providers who can assist you with your child and any possible sound therapy or other treatments at Check under the TRTA list of providers.
