About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

18 years of age or over,

Native French speaker,

Having given their consent to take part in the research.

Adult implanted and declaring that they have been using the implant for at least 18 months,

Disqualifiers

Be under guardianship or curatorship,

deprived of liberty by judicial or administrative decision, or subject to legal protection,

Non- native French speaker.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Speech in noise comprehension test

    Behavioral

    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).

  • Objective tests of perception of ambient sound cues in noise

    Behavioral

    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.

  • Subjective tests of perception of ambient sound cues in noise

    Behavioral

    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.

Treatment groups

50 Participants
