Claim:
1. A binaural hearing aid system comprising two hearing instruments each configured to be worn by a user on either side of the head, wherein each of said hearing instruments comprises an input transducer for receiving a sound signal from the environment and for generating an electrical signal from the received sound signal, and a signal processing unit, one of the signal processing units of the binaural hearing system comprises a frequency filter unit comprising frequency filters for generating a higher frequency part and a lower frequency part of said electrical signal from the corresponding input transducer, and the other signal processing unit comprises a frequency filter unit comprising frequency filters for generating a lower frequency part of said electrical signal from the corresponding input transducer, one of the hearing instruments comprises a transmitter unit configured to transmit said higher frequency part of said electrical signal and the other one of the hearing instruments comprises a receiver unit configured to receive said higher frequency part of said electrical signal, one of the signal processing units further comprises a processing unit for filtering said higher frequency part of said electrical signal with a processing filter prior to transmission of said higher frequency part of said electrical signal by the transmitter unit, or filtering said higher frequency part of said electrical signal with a processing filter after reception of said higher frequency part by the receiver unit, and the signal processing unit in a corresponding one of the hearing instruments is configured for selectively performing one of the following based on a direction of a target sound source relative to the user's head generating a processed electrical signal from a combination of said lower frequency part and said higher frequency part of said electrical signal generated by said frequency filter in said corresponding hearing instrument, and generating a processed electric signal from a combination of said lower frequency part of said electric signal generated by said frequency filter in said corresponding hearing instrument and said higher frequency part of said electrical signal transmitted by the other hearing instrument and filtered with said processing filter.
