  • Publication number: 20240080633
    Abstract: A method operates a hearing system that has first and second hearing devices. In the first hearing device, a first reference signal and a first auxiliary signal are generated from an environment sound collected by microphones. A first pre-processed signal is generated by applying a direction-sensitive pre-processing to the first reference and auxiliary signals using first reference and first auxiliary pre-processing coefficients. For the microphones, a respective first reference head related transfer function and first auxiliary head related transfer function are provided, and a first head related transfer function is derived from the first reference and first auxiliary pre-processing coefficients and from the first reference and auxiliary head related transfer functions. For the second hearing device a second pre-processed signal is generated using second microphones, and a second position related transfer function is provided.

  • Patent number: 10904679
    Abstract: A method for enhancing a signal directionality in a hearing instrument wherein first and second signals are generated by first and second input transducers that are spaced apart from one another. A first directional signal is derived from the first input signal and the second input signal by applying a second-to-first relative transfer function with respect to a first target angle to the second input signal. The second-to-first relative transfer function is a relative transfer function from the second input transducer to the first input transducer with respect to the first target angle. Similarly, a second directional signal is derived from the second input signal and the first input signal by applying a first-to-second relative transfer function with respect to a second target angle to the first input signal. An angle-enhanced signal is derived from the first directional signal and the second directional signal.
