This paper deals with the question of how the general public should be addressed when offering hearing screening. Postal-based questionnaires in the United Kingdom, Germany, and The Netherlands were sent to users of hearing devices, those that are in the process of obtaining one, or those that have indicated that they have special interest in hearing.(More)
Noise reduction algorithms have been proposed that try to imitate some aspects of the binaural information processing in the human hearing system by using two microphones at both ears and a central processor. Based on a two channel input, it is theoretically possible to cancel one interfering directional noise source at a time. Due to the relatively large(More)
The present w ork concerns a system aimed at enhancing a target talker under varying signal conditions based on the use of several dierent t ypes of information or \cues". Toward this end, an architecture designed to combine separately operating estimators is described and evaluated. The architecture is currently implemented using spatial-and(More)
Noise reduction algorithms have been proposed which imitate aspects of the binaural processing in the hearing system. Based on a two-channel input, it is theoretically possible to cancel one interfering directional noise source at a time and to cancel reverberation based on coherence measures. In practice, however, no significant increase in speech(More)
