Summary

The aim of the study is to evaluate the interaural time difference (ITD) benefit in patients with bilateral cochlear implants and to assess speech performance in noisy conditions compared to normal hearing listeners. Half of participants are bilateral cochlear implants users, while the other are normal hearing listeners.

Detailed description

Listening in noisy environments is part of everyday life, it is based on binaural phenomena such as spatial localization.
