Modulation Depth Discrimination by Cochlear Implant Users
Modulation Depth Discrimination by Cochlear Implant Users
Cochlear implants (CIs) convey the amplitude envelope of speech by modulating high-rate pulse trains. However, not all of the envelope may be necessary to perceive amplitude modulations (AMs); the effective envelope depth may be limited by forward and backward masking from the envelope peaks. Three experiments used modulated pulse trains …
