Sound enhancement for hearing-impaired listeners
First Claim
Patent Images
1. A method of enhancing sound heard by a hearing-impaired listener, the method comprisingmonitoring the sound in an environment in which the listener is located;
- andmanipulating the frequency of high frequency components of the sound in a high frequency band while leaving the frequency of components of the sound in a speech frequency band unchanged, to enhance spectral cues to aid the listener in sound externalisation and spatialisation.

Abstract
A method of enhancing sound heard by a hearing-impaired listener comprises monitoring the sound in an environment in which the listener is located; and manipulating the frequency of high frequency components of the sound in a high frequency band, with little, if any, distortion to components of the sound in a speech frequency band, to enhance spectral cues to aid the listener in sound externalisation and spatialisation.

22. Equipment for enhancing sound heard by a hearing-impaired listener, the equipment comprising
at least one hearing aid device comprising: -
a housing to be associated with an ear of the listener;
a sensor associated with the housing for sensing the sound;a delivery medium carried by the housing for delivering processed sound to an auditory system of the listener; a primary signal processing arrangement contained within the housing, the primary signal processing arrangement being configured to perform conventional hearing aid signal processing; and an auxiliary signal processing arrangement in communication with the primary signal processing arrangement, the auxiliary signal processing arrangement being configured to manipulate the frequency of the high frequency components while leaving components of the sound in a speech frequency band substantially unchanged to enhance spectral cues to aid the listener in sound externalisation and spatialisation. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
