The Sophono Bone Conduction Hearing Systems are a family of sound processors and accessories that operate on the principle of BC of sound vibrations. The Sophono Bone Conduction Hearing Systems transmits audio vibrations through the skin into the bone where sound is sensed by the inner ear/cochlea. The Sophono Sound Processor is magnetically attracted to the Magnetic Implant and Magnetic Spacer. The Magnetic Implant, which is secured to the skull bone, affixes the Magnetic Spacer to the head transcutaneously through magnetic attraction forces, and the Sound Processor is magnetically affixed to the Magnetic Spacer. Vibration from the Sound Processor is transduced through the Magnetic Spacer to the Magnetic Implant and through the bone to the inner ear. |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Assess the safety of the Sophono implant
Time Frame: From Implantation to Study Visit, up to 6 years
|
The primary safety endpoint is the proportion of AEs related to the Sophono implant, which will be assessed through retrospective surgical chart review and prospective ENT exam.
|
From Implantation to Study Visit, up to 6 years
|
Assess the effectiveness of the Sophono Alpha 2 MPO processor
Time Frame: 1 day
|
The primary efficacy endpoint is the difference (gain) in the free-field pure tone audiometry assessed by pure tone average (PTA) unaided (AC) and aided (BC) by the Alpha 2 MPO processor.
|
1 day
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Compare the effectiveness of the Sophono Alpha 2 processor to the Alpha 2 MPO processor
Time Frame: 1 day
|
The difference in the free-field pure tone audiometry assessed by PTA aided by Alpha 2 processor compared to the PTA aided by Alpha 2 MPO processor
|
1 day
|
Assess the effectiveness of the Sophono Alpha 2 and the Sophono Alpha 2 MPO over time
Time Frame: From Processor fitting to Study Visit, up to 4 years
|
Change over time of PTA in the Sophono Alpha 2 and Alpha 2 MPO
|
From Processor fitting to Study Visit, up to 4 years
|
Assess subject satisfaction after system use
Time Frame: 1 day
|
Subject satisfaction, via non-validated satisfaction questions
|
1 day
|
