Benefits of amplification and accessories used with it outweigh anticipated risks in mild to profound hearing impaired subjects. The basic benefit of amplification should be present with any method that the trained professional fitting the instruments uses. The goal of this study is to compare two fitting methods and determine whether the end user perceives more benefit from one fitting method over the other. The objective benefit is expected to be the same; however, the subjective benefit may be different due to a possible psychological effect from more effort or time spent by the trained professional.
Bernafon will conduct this clinical investigation to test current hearing instruments fitted with the standard procedure and a self-directed procedure. Safety and performance validation of the new self-directed fitting software is needed before release to the market.
The reason for this study is to evaluate a currently marketed, CE certified, hearing aid and determine whether different fitting methods provide the same perceived benefit. Additionally, this study will validate the safety of the fitting procedure as well as collect post market safety information about the devices themselves. The goal is to evaluate the audiological performance objectively as well as the subjective benefit. Furthermore, it is important to identify unexpected, unwanted behavior from the fitting software and the devices.
