Claim:
1. A hearing system for improving intelligibility during the holding of a telephone conversation, the hearing system comprising: a receiving device for receiving a first signal having first acoustic information and for converting the first signal into electrical signals having the first acoustic information; a recognition device configured to recognize that the first signal is a signal of a telephone conversation and to output a recognition signal; a signal processing device for processing the electrical signals having the first acoustic information into electrical signals having second acoustic information, said signal processing device being configured to perform an artificial bandwidth extension of the first signal by supplementing the first acoustic information with reference to a model of a source of the first signal by acoustic information with missing frequency components to form the second acoustic information, and said signal processing device being configured to carry out the artificial bandwidth extension when the recognition signal is present; and an output device for outputting a second signal having the second acoustic information.
