Abstract
A hearing aid includes an audio signal input device, a signal processor and a signal output device which presents a processed audio signal perceivable as sound to an ear of a user. The signal processor includes fast acting level estimators and slow acting level estimators. A communication link between two hearing aids at each ear of a user allows the transmission between the two hearing aids of level estimates from the slow acting level estimators.
Claims16
A hearing aid, comprising:
- an audio signal input device;
- a signal processor;
- and
- a signal output device which presents a processed audio signal perceivable as sound to an ear of a user, wherein
- the signal processor includes
- fast acting level estimators and
- slow acting level estimators,
- the hearing aid further comprises a binaural communication link operable to transmit and receive data to/from a second, similar, contralaterally placed hearing aid providing sound to a contralateral ear of a user,
- the binaural communication link is operative to transmit level estimates from only the slow level estimators in each of the two hearing aids to the respective contralaterally placed hearing aid, and
- a summation point is provided in each hearing aid operative to combine the level estimates of the ipsilateral hearing aid with the level estimates of the contralateral hearing aid, received via the binaural communication link, according to a summation function.
