Disclosed is method of generating an audible
signal in a
hearing aid by estimating
a weighting function of received audio signals, the
hearing aid is adapted to be worn by a user; the method comprises the steps of:estimating a directional
signal by estimating a weighted sum of two or more
microphone signals from two or more microphones, where a first
microphone of the two or more microphones is a front
microphone, and where a second microphone of the two or more microphones is a rear microphone;estimating a direction-dependent time-frequency
gain, and synthesizing an output
signal;wherein estimating the direction-dependent time-frequency
gain comprises:obtaining at least two directional signals each containing a time-frequency representation of a
target signal and a
noise signal; and where a first of the directional signals is defined as a front aiming signal, and where a second of the directional signals is defined as a rear aiming signal;using the time-frequency representation of the
target signal and the
noise signal to estimate a time-frequency
mask; andusing the estimated time-frequency
mask to estimate the direction-dependent time-frequency
gain.
