An interventional study of Automatic Sound Management Fixed Directionality and Automatic Sound Management Adaptive in Hearing Loss, Sensorineural and Cochlear Implantation, sponsored by Med-El Corporation. Enrolling by invitation at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-03-30.
Sponsored by Med-El Corporation · Not applicable, Interventional, and Treatment
This study will evaluate the speech perception ability of adult cochlear implant users in background noise using various MED-EL Automatic Sound Management (ASM) features.
This study will examine how different sound processing approaches support cochlear implant users' ability to understand speech in noisy environments. Automated noise reduction and microphone directionality systems are known to improve listening comfort and speech clarity in challenging settings. Ongoing refinements in these areas may offer additional benefits and allow for more individualized listening options. In this study, adult cochlear implant users will take part in speech-in-noise evaluations while using various sound processing configurations.

Device: Automatic Sound Management Fixed Directionality · Device: Automatic Sound Management Adaptive · Device: Omnidirectional Settings
The audio processor will be programmed with fixed directional microphones.
Also known as: ASM Fixed Directionality
The audio processor will be programmed with adaptive automatic sound management features.
Also known as: ASM Adaptive
The audio processor will be programmed with omnidirectional microphones and automatic sound management disabled.
Also known as: Omnidirectional
Individual and mean within-subject difference on HINT SNR-50 between ASM Fixed Directionality and Omnidirectional conditions.
Speech perception ability will be measured using the Hearing in noise Test (HINT) sentences in an adaptive procedure. HINT sentences will be presented from the front with continuous, steady-state noise presented at 65 dBA from behind. The presentation level of the speech signal will be adjusted based on participant response. The difference in dB SNR between the ASM Fixed Directionality and Omnidirectional conditions will be summarized. Results for each condition will be reported in dB SNR defined as the SNR level at which 50% score is achieved.
Time frame: 0 days
Individual and mean within-subject difference on HINT SNR-50 between ASM Adaptive settings.
The HINT SNR-50 task will be completed using different adaptive automatic sound management features. The difference in dB SNR between the conditions will be summarized. Results for each condition will be reported in dB SNR defined as the SNR level at which 50% score is achieved.
