Study of Auditory Perception After Progressive Exposure to Aversive Sounds in People With Misophonia

Condition(s) studied

Investigational drug(s) / intervention(s)

Psychoacoustic test: Natural sounds will be presented at different decibels (dB), and the subject will be asked to rate the pleasantness/unpleasantness of the sound heard on a visual analogue scale, as well as the loudness (subjective intensity) of the sound heard.

semi-structured interviews: interview, designed under the supervision of a psychologist and using the methodology of micro-phenomenological interviews the aim of these interviews is to gain access to the participants' experiences, as they describe them in the first person, during misophonic episodes

Exposure to unpleasant sounds: Home exposure is a practice whereby participants voluntarily subject themselves to SMs in a controlled environment. Participants will be asked to complete two tasks: firstly, they will have to expose themselves to all 10 sounds at least twice a week; secondly, they will have to record the annoyance felt for each sound and the subjective loudness (loudness) of each SM using VAS.

Study summary

The primary objective of the project is to characterise and measure the auditory perception of subjects with misophonia compared with the auditory perception of control subjects.

Eligibility

Primary outcome measure(s)

• score on a visual analogue scale from 0 (pleasant sound) to 10 (unpleasant sound) — 1 week after enrollment
  sounds will be presented at different decibels and the subject will be asked to rate the pleasantness/unpleasantness of the sound on a visual analogue scale
• score on a visual analogue scale from 0 (very low intensity) to 10 (extremely intense) — 1 week after enrollment
  sounds will be presented at different decibels and the subject will be asked to rate the intensity of the sound on a visual analogue scale
