Abstract (en)
[origin: US2016057548A1] A method for suppressing acoustic feedback in a hearing aid device and a corresponding device and a system. A frequency range to be transmitted by the hearing aid device is divided into two frequency ranges that are separated by a split-band frequency. A transfer function of a feedback path is estimated in a frequency range and assessed for its behavior at the split-band frequency. Depending on the result of the assessment, the split-band frequency is lowered or raised and in the upper frequency range a phase and/or frequency change is applied for suppressing feedback.
