简要总结
Phonak Hearing Systems pass through different development and study stages. At an early stage, feasibility studies are conducted to investigate new algorithms, features and functions in an isolated manner. If the benefit is proven, their performance is then investigated regarding interdependency between all available algorithms, features and functions running in parallel in a hearing aid (pivotal/pre-validation studies) and, as a result, they get optimized. Afterwards, and prior to product launch, the Phonak Hearing Systems undergo a final quality control in terms of clinical trials. This is a pre-validation study, investigating optimized algorithms, features, functions and wearing comfort. This will be a clinical evaluation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).
详细描述
In this study one CE-labeled Phonak Receiver-in-the-canal (RIC) devices is investigated. The experimental device will be investigated regarding Sound Quality perception ot the T-Coil program. A secondary objective of this study is the investigation of the Overall system stability in daily life situations. The experimental device contains direct connectivity functionality and a T-Coil. The combination of a wireless chip for Bluetooth streaming and a T-Coil in one housing can cause audible artifacts on the T-Coil, which shall be investigated within this study. This will be a clinical evaluation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).

结局指标
主要结局
Subjective perception of the T-Coil Sound Quality
时间窗: 4 weeks
The primary objective of this study is to measure that the overall sound Quality of the T-Coil program \[subjective satisfaction rating on a scale from 0%-100% in 1% steps\] of the investigational device is rated as at least as 60% or better \[60% is the border between 'ok' and 'satisfied'\] after a test period with daily life situations.
次要结局
- Program switch-back workflow into T-Coil program(4 weeks)
