Evaluation of a personalized auditory-cognitive training on the improvement of speech understanding in noise in cochlear implanted patients.

Objective: The cochlear implant is a commonly used implantable device for the auditory rehabilitation of severe bilateral sensorineural hearing loss. The effectiveness of the implant, depends on many factors, including intensive auditory training, which is crucial. Intelligibility in a noisy environment is a current issue and poses a major difficulty for implanted patients. The aim of this study is to evaluate the improvement in auditory performance in noise among cochlear implant patients who underwent personalized auditory-cognitive training for speech understanding tasks in noise.

Design: This was a prospective study involving cochlear implanted patients divided into two groups. One group underwent auditory training in a noisy environment at home for 2 months (G1) while the other group served as a control (G0). A test of intelligibility performance in noise was conducted at inclusion and two months later.

Results: 52 patients were included in the study. The trained group, G1, showed a significant improvement with an increase of 4.8 dB in signal-to-noise ratio (SNR) between the two tests (P < 0.01). There was no significant improvement in the control group (G0) (P = 0.756).

Conclusions: This study demonstrated a significantly positive impact of personalized auditory training in a noisy environment for cochlear implant patients.
