摘要:
A method for reducing noise in an input signal (110) of a hearing device comprising a transfer function (H) as well as a hearing device is disclosed. The method comprises the steps of: capturing first and second acoustic signals by first and second acoustic-electric converters (1, 2), providing first and second input signals (110, 311) by the first and the second acoustic-electric converters (1, 2), deriving an information signal (410) by using the first and the second input signals (110, 311), deriving an information signal estimate (S) from the information signal (410), deriving a noise signal (411) by using the first and the second input signals (110, 311), deriving a noise signal estimate (N) from the noise signal (411), generating instantaneous coefficients (412, 312) for the transfer function (H) by using the information signal estimate (S) and the noise signal estimate (N), applying the transfer function (H) to the first input signal (110) or to a processed first input signal (410) generating an output signal (111), and feeding the output signal (111) to an electro-acoustic converter (5) of the hearing device.
