What were we asked?

We were asked whether noise generators are an effective treatment for hyperacusis in children, and how long should they be worn for?

Key findings

  • People with hyperacusis experience everyday sounds as intrusively loud, uncomfortable and/or painful.
  • The aim of noise generators is to reduce the sensitivity of the ear to gradually improve tolerance of sounds.
  • We did not find any research evidence from clinical trials to inform whether this treatment is effective for children.
  • NHS information suggests that noise generators are often used for twelve to eighteen months, and that during this time period, most people find a long-term improvement in their sensitivity, without needing to continue using them.
