Social Determinants of Health and Adult Cochlear Implantation: A Scoping Review.

Objective: Cochlear implants (CIs) are a cornerstone of hearing rehabilitation for individuals with severe-to-profound hearing loss, yet they remain underutilized among eligible adults. Social determinants of health (SDOH) describe the nonmedical factors shaping health outcomes, including the conditions in which individuals live, work, and age, as well as broader influences like social norms and economic policies. These factors likely contribute to the disparity in CI utilization.

Association of Tonotopic Mismatch With the Speech Recognition of Cochlear Implant Users With Unilateral Hearing Loss.

Objective: Review the relationship of tonotopic mismatch with the speech recognition of cochlear implant (CI) users with unilateral hearing loss (UHL; also known as single-sided deafness).

Patients: Twenty-seven adults (≥18 yr of age) with late-onset UHL.

Intervention: Cochlear implantation.

Estimating Cochlear Implant Users' Sound Localization Abilities With Two Loudspeakers.

The ability to tell where sound sources are in space is ecologically important for spatial awareness and communication in multisource environments. While hearing aids and cochlear implants (CIs) can support spatial hearing for some users, this ability is not routinely assessed clinically. The present study compared sound source localization for a 200-ms speech-shaped noise presented using real sources at 18° intervals from -54° to +54° azimuth and virtual sources that were simulated using amplitude panning with sources at -54° and +54°.
