Quality Control of CE-Certified Phonak Hearing Aids
A methodical evaluation of new CE-labelled Phonak Hearing Systems is intended to be conducted on hard of hearing participants to grant quality control prior to product launch.
The aim of the investigation series is to ensure 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 and to equivalent competitor devices.

Descripción detallada
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).

Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Zero-defect performance in daily life
Periodo de tiempo: Four weeks
|
The data, serving as primary outcomes are collected in a series of home trials taking place between the lab trial appointments.
The zero-defect performance in daily life (that means: no interruptions, distortions, artefacts, feedback, system noise or other malfunctions) will be assessed with the aid of quantitative questionnaires.
The results are "Yes/No" replies and open-ended.

Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Speech intelligibility in percent in a quiet listening situation
Periodo de tiempo: Four weeks
|
The data, serving as secondary outcomes are collected in a series of lab appointments.
The speech intelligibility in quiet will be assessed with the aid of the german rhyme test "Einsilber-Reimtest nach von Wallenberg und Kollmeier" (WaKo).
The result is the speech intelligibility in percent.
Descriptive statistics will be executed in the form of determining the median and quartiles.
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.

Speech intelligility in noise as signal to noise ration in dB (dB SNR)
Periodo de tiempo: Four weeks
|
The data, serving as secondary outcomes are collected in a series of lab appointments.
The speech intelligibility in noise will be assessed with the aid of the german Oldenburger sentence test.
The result is the signal to noise ratio in dB (dB SNR).
Descriptive statistics will be executed in the form of determining the median and quartiles.
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.

Initial first fit acceptance (pre-calculation) in lab
Periodo de tiempo: One week
|
The data, serving other pre-specified outcomes are collected within the first lab appointment.
The acceptance of the initial first fit will be assessed with the aid of quantitative questions within an interview.
The results are points on a scale and open ended (e.g.
Question: Please rate the sound quality; Answer scale: bad, poor, fair, good, excellent) .
Descriptive statistics will be executed in the form of determining number of answers.
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.

Real ear frequency responses of the hearing aids (Real Ear Measurements)
Periodo de tiempo: One week
|
The data, serving other pre-specified outcomes are collected within the first lab appointment.
The Real Ear Measurements (REMs) will be assessed with the aid of quantitative questions within an interview.
The results are frequency responses (magnitude and phase of the hearing aid output as a function of frequency).
