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

• Psychoacoustic test (Behavioral): 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 (Other): 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 (Other): 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.

Primary outcomes

• 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 outcomes

• 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]
