The Effect of Between-Ear Speech Perception Asymmetry on Localization, Spoken Language, and Literacy for Adolescents With Cochlear Implants

A dispatch from PubMed — filed

This study aimed to examine the effects of between-ear speech perception asymmetry on localization, spoken language, and reading in adolescents with early cochlear implants (CIs).

Clinical Takeaway

Audiologists managing adolescent cochlear implant users should assess between-ear speech perception asymmetry, as it may be associated with poorer sound localization, spoken language, and literacy outcomes—though the cross-sectional or observational nature of the study limits causal conclusions.

Why It Matters

Understanding how ear-to-ear hearing imbalance shapes language and literacy development in CI users could guide bilateral fitting strategies and rehabilitation targets for adolescents.

Key Points
  1. 01Between-ear speech perception asymmetry was the primary predictor variable examined in adolescent CI users.
  2. 02Outcomes measured included sound localization, spoken language ability, and literacy (reading).
  3. 03Participants received cochlear implants early in life, allowing study of long-term developmental effects.
  4. 04Findings may have implications for optimizing bilateral CI programming to minimize asymmetry.
  5. 05Published in the Journal of Speech, Language, and Hearing Research (JSLHR).
Claims & Evidence

Between-ear speech perception asymmetry negatively affects sound localization in adolescents with cochlear implants.
