Misophonia
Conditions
Brief 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.
Interventions
BEHAVIORALPsychoacoustic 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.
OTHERsemi-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
OTHERExposure 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.

Inclusion criteria
For all participants * Obtain oral consent from the participant after receiving information about the study, * Be 18 years or older on the day of inclusion, * Be fluent in French (spoken and written), * Have no known hearing loss, verified by pure tone audiometry. * Declare that they do not have tinnitus, * Declare that they do not have hyperacusis, verified by measuring discomfort thresholds. * Be affiliated to the social security or equivalent scheme. For participants with misophonia: \- Declare discomfort, reduced tolerance to specific sounds (mouth noises, throat clearing, breathing, etc.).
Exclusion criteria
* Bear the after-effects of an ear infection and/or have a history of an ENT disease that permanently affects hearing or balance (vestibular schwannoma, Ménière's disease, sudden or fluctuating deafness, congenital hypoacusis), * Be under guardianship, * deprived of liberty by judicial or administrative decision, or subject to legal protection.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Measuring the consistency of the psychoacoustic test | 1 week after enrollement | consistency measured by calculating Cronbach's alpha coefficient |
| the number of redundant themes in the semi-structured interviews | 1 month after enrollment | the interviews consist of open-ended questions covering different aspects of the experiences of misophone subjects |
| score on a visual analogue scale from 0 (very little discomfort) to 10 (extreme discomfort) | 1 month after enrollment and 2 months after enrollment | — |
