Abstract
In this work we present a new method for assessment of directionality in modern hearing aids, which has the benefit of simulating both a target source and an interfering source at the same time using speech signals. We show the benefits and the limitations of the method and present measurements for different microphone modes of different manufacturers. Furthermore, a sequential index based on these measurements is introduced.
