Benefits of technology

This technology allows for more flexibility when selecting different types of testing signals based on their actual needs or circumstances during use. It also avoids manually adjusting certain tests while still being able to detect how well they are working with them.

Problems solved by technology

The technical problem addressed in this patented text relates to improving testing accuracy when running an adaptive listening device without affecting how much sound comes into playback compared to what it should be playing back correctly.

Abstract

An apparatus for testing a directional hearing instrument includes: a first microphone for coupling with an output of the hearing instrument, wherein the first microphone is configured to receive an audio output signal from the hearing instrument; a first speaker for transmission of a first signal having a first frequency component at a first frequency; a second speaker for transmission of a second signal having a second frequency component at a second frequency; and a processing unit configured to determine one or more hearing instrument parameters based on cross spectrum analysis of the first signal and the audio output signal.
