Abstract
Hyperacusis is a condition that is characterized by hypersensitivity to normal everyday sounds or reduced sound tolerance and can affect patients in distressing ways. Sound therapy is a treatment intervention that is used to desensitize patients. However, as yet, there is a lack of understanding on how it is used in clinical practice, the different types of devices, or how to use them. The aim of this scoping review was to establish the current use of sound therapy in adults with hyperacusis and identify any factors that may influence treatment. Methodology: An established methodological framework was used to formulate the research question and guide the search strategy and reporting. The inclusion criteria were studies reporting adult (>18 years) populations with hyperacusis and sound therapy treatments which were published in any language. Searches of electronic databases (CINAHL, Cochrane Library, Medline (EBSCO), Scopus, PsycINFO) identified 31 studies that met the inclusion criteria (completed in April 2024). Data from included records were collated and summarized descriptively.
