Performance of a Hearing Aid Platform Including Different Styles of Hearing Aids

This is a controlled, single blinded comparative study which is conducted monocentric at Phonak Headquarters in Staefa. The focus is to compare a new hearing aid product generation with the one on the market as well as with competitor devices regarding the audiological performance, usability as well as features and functions with the aid of 382 mild to profound hearing impaired subjects (18-90 yrs). The subjects, all of them native (Swiss) German speakers, individually conduct a number of laboratory standard tests and home trials (questionnaires) during nine weeks including weekly appointments of 2 hours.
