Abstract:
The application relates to a binaural hearing system comprising left and right hearing devices, e.g. hearing aids, each comprising a) a multitude of input units, each providing a time-variant electric input signal x i (t) representing sound received at an i th  input unit, t representing time, the electric input signal x i (t) comprising a target signal component s i (t) and a noise signal component v i (t), the target signal component originating from a target signal source; b) a configurable signal processing unit for processing the electric input signals and providing a processed signal y(t); c) an output unit for creating output stimuli to the user, d) transceiver circuitry allowing information to be exchanged between the hearing devices, and e) a binaural speech intelligibility (SI) prediction unit for providing a binaural SI-measure of the predicted speech intelligibility of the user when exposed to said output stimuli, based on processed signals y l (t), y r (t) from the signal processing units of the respective left and right hearing devices. This allows the hearing devices to control the processing of the respective electric input signals based on said binaural SI-measure.

Claim (Index 17):
A method of providing a binaural speech intelligibility predictor in a binaural hearing system according to  claim 1 , the method comprising\n modelling a potential hearing loss by adding uncorrelated noise, spectrally shaped according to the hearing loss of the user; estimating the inter-aural target and noise covariance matrices for each frequency sub-band of the output signals of the left and right hearing devices; estimating SNR-optimal beamformers in the form of, generally complex-valued, beamformer weights for each frequency band for the left and right hearing devices, respectively; generating jittered beamformer weights by applying jitter to the beamformer weights for each frequency band for the left and right hearing devices, respectively; applying jittered beamformer weights to the output signals of the left and right hearing devices thereby providing an apparent signal-to-noise ratio as a function of time and frequency; producing a final estimate of the speech intelligibility experienced by the user.
