Sensitivity to haptic sound-localisation cues

Abstract Hearing aid and cochlear implant (CI) users often struggle to locate and segregate sounds. The dominant sound-localisation cues are time and intensity differences across the ears. A recent study showed that CI users locate sounds substantially better when these cues are provided through hap...

The dominant sound-localisation cues are time and intensity differences across the ears.
