Abstract
Disclosed herein are embodiments of a hearing aid configured to be worn by a user at or in an ear of the user and having an ITE-part adapted for being located at or in an ear canal of the user. The hearing aid can include an active occlusion cancellation system (AOCS) for providing an acoustic anti-occlusion signal configured to cancel or diminish a sense of occlusion of the user when the user is speaking, or otherwise is using his or her voice, or when otherwise moving the jaws. Methods of operating a hearing aid are further disclosed.
Claims20
A hearing aid configured to be worn by a user at or in an ear of the user, the hearing aid comprising:
- an ITE-part adapted for being located at or in an ear canal of the user;
- at least one first input transducer configured to provide corresponding at least one first electric input signal representing sound;
- a hearing aid processor configured to provide a processed signal in dependence of said at least one electric input signal;
- a first output transducer configured to play sound to the user in dependence of said processed signal, or a signal dependent thereon;
- an active occlusion cancellation system for providing an acoustic anti-occlusion signal configured to cancel or diminish a sense of occlusion of the user when the user is speaking, or otherwise is using his or her voice, or when otherwise moving the jaws;
- wherein the active occlusion cancellation system comprises:
- an ear canal input transducer located in said ITE-part and configured to provide an electric ear canal input signal representing sound in said ear canal, when the user wears the hearing aid;
- an ear canal sound estimation unit configured to estimate sound in said ear canal and to provide an electric anti-occlusion signal in dependence of said electric ear canal input signal and said processed signal;
- a second output transducer located in said ITE-part configured to play sound to the user and to provide said acoustic anti-occlusion signal in dependence of said electric anti-occlusion signal, wherein said second output transducer is specifically adapted to provide sound at frequencies below a threshold frequency.
