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.

摘要： The method of manufacturing a hearing system adapted to the fitting hearing needs and preferences of an individual, said hearing system having adjustable parameters, wherein the method comprises the steps of : a) presenting to said individual an audiovisual presentation having an interactively variable plot; b) during step a) : receiving a user input (U1;U2) from said individual; c) during step a) : directing said plot in dependence of said user input (U1;U2); d) determining a setting for at least one of said adjustable parameters in dependence of said user input (U1;U2); and preferably also e) setting said setting for said at least one adjustable parameter. This allows to obtain good fitting results within a short period of time.
