Correction of the Estimated Hearing Level of NB Chirp ABR in Normal Hearing Population.

Audiol Neurootol 2022 Apr 20:1-9. Epub 2022 Apr 20.

ColIege of Otolaryngology Head and Neck Surgery, Chinese PLA General Hospital, Beijing, China.

Introduction: The narrowband chirp (NB Chirp), a frequency-specific sound stimulus signal obtained by limiting the frequency bandwidth based on chirp, is applied to the frequency specified auditory brainstem response (fsABR) increasingly. Although some studies demonstrated that NB Chirp-evoked auditory brainstem response (NB Chirp ABR) causes a better neural response than tone burst-evoked auditory brainstem response and is preferred for fsABR, there is little known about how to better estimate an individual's hearing level through the threshold of NB Chirp ABR. The present study intended to compare the accuracy and deviation of NB Chirp ABR corrected by different approaches in estimating the hearing level of people with normal hearing. Read More

Sound Source Localization by Cochlear Implant Recipients with Normal Hearing in the Contralateral Ear: Effects of Spectral Content and Duration of Listening Experience.

Audiol Neurootol 2022 Apr 19:1-12. Epub 2022 Apr 19.

Department of Otolaryngology/Head & Neck Surgery, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, USA.

Introduction: Cochlear implant (CI) recipients with normal hearing (NH) in the contralateral ear experience a significant improvement in sound source localization when listening with the CI in combination with their NH-ear (CI + NH) as compared to with the NH-ear alone. The improvement in localization is primarily due to sensitivity to interaural level differences (ILDs). Sensitivity to interaural timing differences (ITDs) may be limited by auditory aging, frequency-to-place mismatches, the signal coding strategy, and duration of CI use. Read More
