Not Applicable

Active, not recruiting

• Conditions: Hearing Loss, Mixed Conductive-Sensorineural; Hearing Loss, Conductive
• Interventions: Device: Cochlear Osia 3 Sound Processor; Device: Cochlear™ Osia® 2 Sound Processor

• Registration Number: NCT06338670
• Lead Sponsor: Cochlear

Brief Summary

This study aims to investigate the clinical performance of the Osia 3 Sound Processor in comparison to the Osia 2 Sound Processor in adults with mixed or conductive hearing loss or single-sided deafness implanted with an Osia implant. Participants will attend four study visits, where they will complete various hearing assessments using the Osia sound processors.

Arm && Interventions

Group	Intervention	Description
Cochlear™ Osia® System	Cochlear Osia 3 Sound Processor	Participants will receive the Osia 3 and Osia® 2 sound processors. They will then complete a series of assessments designed to evaluate the clinical performance of these two sound processors. These assessments will take place across four study visits.

Primary Outcome Measures

Name	Time	Method
Change (within subject) in aided thresholds in sound field measured at 0.25, 0.5, 0.75, 1.0, 1.5, 2.0, 3.0, 4.0, 6.0 and 8.0 kHz	During week 24-26	Aided thresholds in sound field will be measured using warble tones presented from a front speaker positioned at 1 m from the subject following the modified Hughson-Westlake procedure. Frequencies to be tested are 250, 500, 750, 1000, 1500, 2000, 3000, 4000, 6000 and 8000 Hz.
Change (within subject) in speech reception threshold in noise with fixed noise level at 65 dB SPL	During week 24-26	Speech perception in noise will be measured using the Australian Speech Test in Noise (AuSTIN), which is a test that uses Bamford-Kowal-Bench (BKB)-like target sentences presented in adaptive noise. The AuSTIN corpus comprises 80 lists of 20 sentences each, recorded in female voice. The goal of the adaptive Speech-in-Noise test is to obtain the Speech Reception Threshold in noise.
Percentage of participants who preferred Osia 3 over Osia 2 sound processor	During week 24-26	Participants will be asked which device they prefer after having listened with both devices (Osia 2 and Osia 3) to different sound clips.
Change (within subject) in the subjective rating of different aspects of sound when listening to sound clips	During week 24-26	After listening to different sound clips with Osia 3 and the Osia 2 sound processors, the subjects will rate specific aspects of the sound, e.g., loudness or sound quality, on a Likert scale from 1 to 5 in steps of 1. A rating of 1 is least positive while a rating of 5 is most positive. They will also be asked to explain their sound quality experience in their own words per sound clip.
Change (within subject) in word recognition score in quiet measured at 65 dB SPL	During week 24-26	Speech perception in quiet will be measured using the consonant-nucleus-consonant (CNC) monosyllabic words presented at 65 dB SPL from the front speaker. The goal of speech perception assessment in quiet is to obtain the percentage of correctly repeated words in a list, i.e., the word recognition score.
