Summary

The COMPRESSED project is a descriptive, bi-centric and non-invasive study carried out by the CERIAH - IDA - Institut Pasteur and the Haute École Léonard de Vinci in Brussels on volunteer participants identified in two groups : * be subject to high exposure to compressed sound, as defined by professional participation in events on broadcast platforms using sound signal processing systems, over the last 3 years, * be subject to moderate or limited exposure to compressed and manipulated sound, equivalent to that of a student following certain distance learning courses. on a videoconferencing platform, alternating with other face-to-face courses, with the ability to listen during breaks, which have been taught for a maximum of 2 years. The main objective of the COMPRESSED study is to evaluate the auditory effects of exposure to manipulated sounds (compression, filtering, equalisation, accentuation, etc.) from sound distribution platforms on the auditory system of participants who are regularly exposed to these sounds as a result of their professional activity.

Conditions

• Auditory Perception

Interventions

Type	Name	Description
OTHER	Audiological profile	Video otoscopy Tympanometry High-frequency tonal audiometry
OTHER	Hearing self-assessments	Hearing skills questionnaire Subjective assessment of tinnitus using a visual analogue scale Self-questionnaire on the impact of tinnitus Hyperacusis self-questionnaire
OTHER	Objective and subjective audiological tests	Acoustic Omission Measurement of the stapedial reflex by tympanometry High-frequency tonal audiometry - exposed ear only Speech audiometry in noise Tinnitus and subjective discomfort thresholds Psychoacoustic intensity perception test
OTHER	Self-assessment of exposure sound quality	A self-assessment of the sound quality of the manipulated sounds heard during the exhibition will be carried out during the second follow-up visit. The elements on which the participant will be asked to make a qualitative judgement will relate to intelligibility difficulties or not; background noise (these two items in the form of a mark between 0 and 10); the clear, muffled or shrill nature of the sounds, their resonant or saturated side.
