  • Test system for evaluating feedback performance of a listening device
    Patent number: 9204225
    Abstract: A test system for evaluates acoustic feedback characteristics of a listening device by changing the transfer function of the signal path from an acoustic output to an acoustic input of the listening device. A variable filter comprises an acoustic input, an acoustic output, and a control unit for changing a transfer function of the filter. First and/or second acoustic propagation elements propagate acoustic sound, the first acoustic propagation element acoustically connecting the acoustic output of the listening device with the acoustic input of the variable filter, the second acoustic propagation element acoustically connecting the acoustic output of the variable filter with the acoustic input of the listening device; wherein the system is configured to allow a determination of acoustic feedback or a level of acoustic feedback of the listening device at different frequencies.
