Hearing aids are a great help for many hearing-impaired people. However, even state-of-the-art hearing aids do not fully restore people’s hearing abilities. This is particularly noticeable in complex acoustic situations with several people talking at the same time or in noisy environments, where it is difficult to follow a conversation. Recent approaches in hearing technology have focused on ways to steer hearing aids via cognitive control, in an attempt to only amplify the sound in an acoustic scene the user is interested in and attending to. In this thesis, the idea of using the eye gaze to control sound amplification in a multi-talker environment and possibilities to implement such steering in a hearing aid are explored. The potential improvement achieved via the steering of audio using the eyes was evaluated on hearing-impaired subjects over several studies. Throughout most of those studies, the orientation of the eyes was estimated using electrodes placed in the ear canals of the subjects. Overall, this thesis demonstrated the potential of using eye gaze steering to improve speech intelligibility, and that the estimation of the orientation of the eyes is achievable using only sensors placed in and around the ear.
