MECHANISMS OF LOCALIZATION AND SPEECH PERCEPTION WITH COLOCATED AND SPATIALLY SEPARATED NOISE AND SPEECH MASKERS UNDER SINGLE-SIDED DEAFNESS WITH A COCHLEAR IMPLANT
In: Ear Hear (2019)
Abstract: OBJECTIVES: This study tested participants with a cochlear implant (CI) in one ear and acoustic hearing in the other ear, to assess their ability to localize sound and to understand speech in collocated or spatially separated noise or speech maskers. DESIGN: Eight CI users with contralateral acoustic hearing ranging from normal hearing to moderate sensorineural hearing loss were tested. Localization accuracy was measured in five of the participants using stimuli that emphasized the separate contributions of interaural level differences (ILD) and interaural time differences (ITD) in the temporal envelope and/or fine structure. Sentence recognition was tested in all eight CI users, using collocated and spatially separated speech-shaped Gaussian noise and two-talker babble. Performance was compared with that of age-matched normal-hearing (NH) listeners via loudspeakers or via headphones with vocoder simulations of CI processing. RESULTS: Localization improved with the CI, but only when high-frequency ILDs were available. Participants experienced no additional benefit via ITDs in the stimulus envelope or fine structure using real or vocoder-simulated CIs. Speech recognition in two-talker babble improved with a CI in 7 of 8 participants when the target was located at the front and the babble was presented on the side of the acoustic-hearing ear, but otherwise showed little or no benefit of a CI. CONCLUSION: Sound localization can be improved with a CI in cases of significant residual hearing in the contralateral ear, but only for sounds with high-frequency content, and only based on ILDs. In speech understanding, the CI contributed most when it was in the ear with the better signal-to-noise ratio with a speech masker.
