Abstract

A hearing aid configured to be worn by a user at or in an ear of the user, comprises • 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 (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; 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 (ECSE) 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; and • 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. A method of operating a hearing aid is further disclosed.
