Some information about hyperacusis

  • This term is used to describe a high level of sensitivity to sound

  • Children with hyperacusis will experience abnormal discomfort to sounds that would be tolerated by most children

  • Children with hyperacusis are unlikely to have a hearing loss

  • Not all sounds of the same loudness cause discomfort

  • Some softer sounds can cause discomfort

  • Hyperacusis appears to be linked to the way the brain processes sound

  • Hyperacusis most commonly occurs on its own but can be linked to other conditions and syndromes including tinnitus, autism, photophobia, chronic fatigue syndrome, depression and Williams syndrome – better not leave that out!!!!




  • Distressing sounds can include sudden loud noises like thunder, objects falling or balloons bursting, hand clapping, electrical noises like vacuum cleaners and electric shavers, loud music, and in some cases even people's voices or laughter.




  • Very specific phobic or aversive responses may be produced by sounds in a specific context e.g. the sound of pen on paper, body sounds such as eating or sneezing, the sound of shovelling cement etc. Other much louder sounds, without significance, may be tolerated normally.

Signs and symptoms



  • The noises are often very distressing to the children, who will typically put their hands over their ears and cry, or try to avoid the sounds, for example by leaving the room or turning off the television or radio.

  • Some children become particularly distressed in crowded, noisy classrooms or in other settings where there is a lot of activity and noise (Tautology? Rephrase?)

  • Children with hyperacusis may present with normal hearing thresholds(on an audiogram) but loudness discomfort levels are typically reduced.

  • Affected children may have difficulty hearing speech in noisy, or poor listening conditions.

  • When an unwelcome sound occurs children with hyperacusis may show signs of anger, distress or panic. The link with their behaviour may not be obvious.

  • Children with hyperacusis may be inexplicably and unreasonably nervous of particular activities or rooms (where they have experienced distressing sounds before)

  • In severe cases, children may refuse to attend school at all.

Some strategies



  • Observe and note any sound to which the child shows an abnormal or aversive reaction

  • If possible try to include the child in this task This is really not clear, and you don’t want to immediate;y force the child to take part.

  • Once you have a list of unwelcome sounds ????

  • Treat the child’s aversion to sound sympathetically, and do not force them to be exposed

  • Reassurance and a clear and simple explanation about the source of the noise often helps.

  • Whenever possible provide a warning just before predictable noises (e.g. fire drills, school bells or before switching on the food processor).

  • The reactions will often diminish if the child is able to exercise some control over the sounds that cause discomfort. For example, encourage the child to turn on the television, or to help with classroom tasks by turning on the washing machine or food mixer.

  • The child may be reassured if he knows that he can leave the room for a few minutes at any point, if he is exposed to a distressing noise.

  • Repeated gentle exposure to the sound will gradually reduce the sensitivity of the auditory nervous system. For example, tape record one or more distressing sounds and encourage the child to play back the tape, quietly at first, then gradually increasing the volume. .

  • School and parents should work together with a slow programme for returning to normal noise exposure. If the programme is too rapid the aversion to sound will be increased

  • Reward the child for progress, never criticize a reaction

  • It is essential that parents, teachers and children understand the mechanism of hyperacusis and phobophobia, as well as possible. More information is available on www.tinnitus.org as well as advice about professional help, if this is needed

  • Even if hyperacusis is part of another syndrome requiring separate treatment, the hyperacusis can respond independently, to these strategies

Sound enrichment

Although children with hyperacusis often seek silence, this has the same effect as avoiding an allergy, or a phobic situation. Sensitivity and strength of reaction increases.

Encourage children to have gentle background sounds all the time, especially at night. Water sounds are often best and commercial devises are widely available, though music or a fan may be preferred. Always let the child choose.

It is essential that the child enjoys the sound used for enrichment.



If wearable sound generators are prescribed (as part of a retraining programme which is available from good audiology departments), these should be encouraged during school hours. Often they produce a quite rapid reduction in sound intolerance when worn, and may facilitate participation in activities otherwise avoided.

Avoid silence!
