NCT06420921

Brief Summary

The goal of this interventional study is to describe how people with cochlear implants perceive the perceive speech in noise and their sound environment on adults who are native French speakers with typical hearing or with cochlear implant(s). The measures and strategies developed in this project could benefit all current and future cochlear implant wearers by improving their perception of the sound environment and their quality of life on a daily basis. Researchers will compare normal hearing participant and participants with cochlear implant to describe the speech in noise and their perception of the sound environment. Participants will perform audiological tests to assess their perception of the sound environment, with and without speech enhancement.

Outcome Measures

Primary Outcomes (1)

  • percentage of environmental sound cues correctly identified when presented simultaneously with other signals

    2 years

Secondary Outcomes (7)

  • comparison of the percentages of correctly identified environmental sound cues obtained objectively and deduced from the signal-to-noise ratio corresponding to the trade-off indicated by the participant

    2 years

  • the percentages of words correctly repeated by participants using non-personalised speech enhancement strategies

    2 years

  • percentages of words correctly repeated by participants using personalised speech enhancement strategies

    2 years

  • comparison of the percentages of correctly identified sound cues and the SNR corresponding to the subjective trade-off

Interventions

Speech in noise comprehension tests consisting of listening to a speech source and one or more competing sources (noise, speech or sound cues) simultaneously. The volunteers will have to repeat the speech source in order to assess intelligibility for each situation, as a function of the intensity ratio of the two sources (SNR).

Normal hearing participantsParticipants with cochlear implant

Tests of perception of the sound environment consisting of listening to a source of noise, sound cues and a competing source of speech simultaneously. The volunteers will have to identify sound cues in order to assess the ability to perceive the sound environment for each situation, depending on the intensity ratio of the different sources.

Normal hearing participantsParticipants with cochlear implant

Tests of perception of the sound environment consisting of listening to a source of noise, sound cues and a competing source of speech simultaneously. Using a simple interface, the volunteers will have to identify the intensity ratio of the sources that they consider to be the best compromise between understanding speech and perceiving the sound environment.
