Precedence-effect with cochlear implant simulation

Cochlear implants (CIs) help many patients to understand speech in quiet and in acoustically dry environments. However, patients still encounter great difficulties in situations of speech-in-noise or in reverberation. The precedence- effect paradigm can be used to study the impact of reflections on perception. It describes the perceptual suppression of a delayed sound copy in the presence of a leading sound. From the view of auditory scene analysis, precedence can be seen as the inability to segregate the lead and lag sounds into two separate objects.
