• Conditions: Auditory Perception

• Registration Number: NCT06691087
• Lead Sponsor: Institut Pasteur

Brief Summary

The aim of the ETERNEL project will be to study the influence of the perception of a single sound timbre on the understanding of a complex sound scene in hearing-impaired people with hearing aids. This will be done by quantifying the inability to manage a complex sound scene as a function of the timbre of the sounds making it up. The more a sound interferes with understanding the complex sound scene, the more salient that sound is considered to be. In this way, the investigators can determine which timbre dimensions make sounds particularly salient for the hearing impaired.

Primary Outcome Measures

Name	Time	Method
Percentage of correct answers in melody comparison tasks in the hearing-impaired group compared with the normal-hearing group,	3-hours

Secondary Outcome Measures

Name	Time	Method
Characterisation of the dissimilarity between pairs of stimuli measured by a continuous perceptual scale	3-hours	Continuous perceptual scale ranging from very dissimilar to very similar
Evaluation of the perceived loudness level of a set of stimuli, measured using scales of magnitude.	3-hours	11-point Likert scale
Comparison between the results of speech audiometry in noise, i.e number of words correctly repeated, with native settings versus settings minimising the discomfort of salient sounds for each participant with hearing loss.	up to 24 months	the comparison will focus on the number of words correctly repeated on the 1st visit (with native settings) versus the last visit (with settings minimising the discomfort)
