Combined Electric and Acoustic Hearing (EAS) for Hearing Loss

This study is looking at how well a combined electric and acoustic hearing (EAS) system works for children and adults with hearing loss. EAS combines a cochlear implant (CI) and a hearing aid (HA) in the same ear. Researchers want to see if using EAS helps people understand speech better, especially in noisy places. You might be able to join if you are aged 5 or older and have normal hearing, or if you have at least one cochlear implant and some low-frequency hearing. The study aims to enroll 160 participants. Success will be measured by improvements in speech recognition scores over time. The current recruitment status is unclear.

Study design
This is an interventional study planning to enroll 160 participants, including children and adults with normal hearing or a cochlear implant and low-frequency hearing.
What's involved
You would receive a clinical fitting of an FDA-approved EAS system. Your speech recognition in noise will be measured at multiple times, including at or within 1 month, 6 months, and 12 months after EAS activation, with an additional measurement at 24 months for children.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for up to 12 months (adults) or 24 months (children) after EAS activation to measure speech recognition scores.

  • Change in BEL sentence score demonstrating EAS benefit for speech recognition in noise (CIHA+HA - CI+HA)This will be measured at multiple time points including at or within 1 month of EAS activation (adults & peds), 6 months (adults & peds), 12 months (adults & peds, and 24 months (peds)

    Speech recognition will be assessed with co-located (S0N0) and spatially separated noise (S0N90 and S0N270) using the BEL sentences with two different male or female talkers as the maskers. Target speech will be fixed at 70 dB SPL for both speech stimuli and the investigators will assess performance for two listening conditions: CI+HA and CIHA+HA.

  • Change in BKB-SIN score demonstrating EAS benefit for speech recognition in noise (CIHA+HA - CI+HA)This will be measured at multiple time points including at or within 1 month of EAS activation (adults & peds), 6 months (adults & peds), 12 months (adults & peds, and 24 months (peds)

    Speech recognition will be assessed with co-located (S0N0) and spatially separated noise (S0N90 and S0N270) using the BKB-SIN test with multi-talker babble as the masker. Target speech will be fixed at 70 dB SPL for both speech stimuli and the investigators will assess performance for two listening conditions: CI+HA and CIHA+HA.
