Description of intervention(s) / exposure
Treatment: Devices - New hearing aid loudspeaker
Treatment: Devices - Standard hearing aid loudspeaker
Experimental: New hearing aid loudspeaker - The new hearing aid loudspeaker is a loudspeaker system with a modified acoustic coupling approach which will be fitted based on the participants' individual ear anatomy.
Active comparator: Standard hearing aid loudspeaker - The hearing aid loudspeaker is a loudspeaker system with the existing acoustic coupling approach which will be fitted based on the participants' individual ear anatomy.
Treatment: Devices: New hearing aid loudspeaker
The new hearing aid loudspeaker will be fitted to the participants individual ear anatomy and hearing loss.
Treatment: Devices: Standard hearing aid loudspeaker
The standard hearing aid loudspeaker will be fitted to the participants individual ear anatomy and hearing loss.

Outcomes
Primary outcome [1]

0
Evaluation of speech intelligibility and sound quality for different loudspeaker
Query!
Assessment method [1]
0
0
The Primary Outcome measure of this study is the comparison of the standard hearing aid loudspeaker with the modified one in regard to speech intelligibility in a noisy environment and sound quality in a quiet situation.
The speech intelligibility will be measured using a speech test in dB SRT and the sound quality will be assessed by subjective rating, using percentage of satisfaction from "very satisfied (100)" to "very unsatisfied (0)".

Summary
Brief summary
Sonova 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 Sonova Hearing Systems undergo a final quality control in terms of clinical trials. This is a confirmatory study, investigating benefits of a modified hearing aid loudspeaker. This will be a clinical investigation which will be conducted mono centric at National Acoustic Laboratories a well known institution with exceptional experience (Australia).
