Abstract

Hearing in noise is the largest problem reported by hearing-impaired people and the problem often persists after hearing aid fitting. Hearing aid directionality is used to increase the signal-to-noise ratio, but also introduce problems as inaudibility. To address this audibility issue GN ReSound introduced asymmetric fittings. The solution, however, contained problems related to directional microphone technology, such as noise introduced as a result of the equalizing for inherent low-frequency roll-off. To solve these issues the strategy for asymmetric ttings was further developed, resulting in the next generation of asymmetric fitting. This article will review the background for asymmetric ttings. Results from earlier studies will be summarized and issues that have been identi ed with GN ReSound’s launch of rst generation of asymmetric tting, Natural Directionality, will be discussed. Further research has been carried out addressing those identi ed issues and the solutions will be presented. Clinical data will back up improvements in GN ReSound’s next generation of asymmetric fitting, Natural Directionality II.
