A hearing system comprises a) at least one hearing device adapted for being worn on the head, or fully or partially implanted in the head, of a user, and b) a multitude of external, spatially separated, audio transmitters, each providing respective external electric sound signals comprising audio. The hearing system is configured to allow wireless communication, including audio communication, between said hearing device and said external audio transmitters, at least from said external audio transmitters to said at least one hearing device, to be established. The at least one hearing device comprises A) a multitude of microphones, each providing an electric input signal representative of sound; B) a beamformer filter providing a beamformed signal from said multitude of electric input signals; and C) an output unit configured to provide stimuli perceivable by the user as sound. The hearing system further comprises c) a selector/mixer for selecting and possibly mixing one or more of said electric input signals or said beamformed signal from the hearing device and said external electric signals from the audio transmitters and to provide a current input sound signal based thereon intended for being presented to the user, possibly in a further processed form. The selector/mixer is controlled by a source selection control signal provided by a source selection processor. The source selection processor is configured to determine said source selection control signal in dependence of a comparison of said beamformed signal and said external electric sound signals or processed versions thereof. A hearing device, and a method of operating a hearing system is further disclosed. The invention may e.g. be used in hearing aids, headsets, active ear protection devices, headphones, etc.

Presented herein are low-power active bone conduction devices that comprise an actuator that is subcutaneously implanted within a recipient so as to deliver mechanical output forces to hard tissue of the recipient. The low-power active bone conduction devices include an energy recovery circuit configured to extract non-used energy from the actuator and to store the non-used energy for subsequent use by the actuator. The low-power active bone conduction devices may also include a multi-bit sigma-delta converter that operates in accordance with a scaled sigma-delta quantization threshold value to convert received signals representative of sound into actuator drive signals.

A hearing assistance device which is worn by the user and which can suppress the voices produced by the user wearing the hearing assistance device is provided. When the user wears the hearing assistance device 1, a pair of microphones is separated and positioned on both sides of a head of the user and a pair of speakers is separated and positioned on both ears of the user or positioned near the ears and which emits sound. The hearing assistance device includes a noise canceller 96 which subtracts a signal processed by a mouth directivity sound processor 93 from the input signal from at least one of the microphones L and R, in which the mouth directivity sound processor 93 emphasizes voice produced from a sound source positioned at a mouth of the user.
