简要总结
A methodical evaluation of new CE-labelled Phonak Hearing Systems is intended to be conducted on hard of participants with a hearing loss to grant quality control prior to product launch. The aim of the investigation series is to ensure usability, zero-defect overall performance of the new hearing systems as well as maximum benefit for the participant with the devices in comparison to previously outstanding Phonak Hearing Systems.
详细描述
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 in the way as planned for this study ("phase of final inspection"). This will be a controlled, single blinded and randomised active comparator clinical evaluation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).

结局指标
主要结局
Usability (phone calls)
时间窗: One week
The data, serving as primary outcomes are collected in a lab appointment. The participants will be asked to accept, reject and hang up phone calls with the aid of the push button of the hearing aid. The usability will be subjectively assessed by the participants and additionally by the investigators on given scales. Descriptive statistics will be executed. Interference statistics will be executed by applying the appropriate parametric or non-parametric test, depending on the data's distribution. A significance level of 5% is pursued.
次要结局
- Zero-defect performance in daily life(Three weeks)
- Speech intelligibility in noise as signal to noise ratio in dB (dB SNR)(One week)
