Quality Control of CE-Certified Phonak Hearing Aids - 2018_28

Not Applicable

Completed

• Conditions: Hearing Loss; Sensorineural Hearing Loss
• Interventions: Device: Phonak Audéo B90; Device: Successor of Phonak Audéo B90

• Registration Number: NCT03718975
• Lead Sponsor: Sonova AG

Brief Summary

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 investigation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).

Detailed Description

In this study a comparison with two CE-labeled Phonak Receiver-in-the-canal (RIC) devices is done. The experimental device and the active comparator will be compared regarding Sound Quality perception and speech intelligibility in Quiet and in Noise. The experimental device contains direct connectivity functionality which will be investigated in terms of streamed Audio quality, streaming stability and Usability preferences of functions and Features which are related to direct connectivity. The active comparator device does not contain direct streaming functionality. This will be a clinical investigation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).

Arm && Interventions

Group	Intervention	Description
Phonak Audéo B90	Phonak Audéo B90	The Phonak Audéo B90 is the most recent Receiver-in-the-canal Hearing aid from Phonak which will be fitted to the participants individual Hearing loss.
Successor of Phonak Audéo B90	Successor of Phonak Audéo B90	The successor of the Phonak Audéo B90 is a Receiver-in-the-canal Hearing aid with direct connectivity functionality from Phonak which will be fitted to the participants individual Hearing loss.

Primary Outcome Measures

Name	Time	Method
Evaluation of subjective acceptance of the default Hearing aid setting	10 weeks	The Primary Outcome measure of this study is the comparison of the default Hearing aid Fitting (first fit) in regard of the subjective acceptance rating between the experimental device and the active comparator (non-inferiority test design). The first fit acceptance will be measured via subjective satisfaction rating of different dimensions concerning sound quality perception and loudness perception (Scale of satisfaction rating ranging from 0% to 100%).

Secondary Outcome Measures

Name	Time	Method
Subjective Sound Quality rating of streamed telephone call (experimental device only)	10 weeks	The secondary Outcome measure of this study is the Evaluation of the perceived Sound Quality (rated via subjective satisfaction rating) of the streamed telephone signal, which will be streamed between a smartphone and the experimental device.
