Outcomes
Primary Outcome Measures
Visibility and Wearing Comfort
The primary objective of this study is to evaluate if Virto B-Titanium hearing aids measured with the Titanium FitGuide (TFG) (extension of Virto B-Titanium) are less visible (deeper) than modeling without TFG (Virto B-Titanium) while maintaining wearing comfort on adult participants (new and existing users) with mild to moderately-severe hearing loss (M and P receiver ).
Secondary Outcome Measures
Measurement of acoustic Feedback Thresholds
Secondary objective is to compare the acoustic feedback thresholds of the TFG- and without TFG- modeled devices in regard of an adequate sealing effect of the respective devices. Thereby, feedback thresholds, measured with the Phonak Target fitting software, must be comparable to average feedback threshold values of the respective shell forms (IIC / CIC). Acceptable feedback thresholds must guarantee an insertion gain [in dB SPL] of at least 20 dB in a specific frequency range.

5. Study Description
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 evaluation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).
