1. A hearing device configured to be worn on the head at or in an ear of a user, wherein the hearing device comprises:
a processor configured to provide a processed signal in dependence of M electric input signals, each of the M electric input signals being indicative of a sound in an environment of the hearing device, and
an output unit configured to provide an output signal in dependence of the processed signal,
wherein the processor is configured to:
determine an unconstrained estimate of a current acoustic transfer function vector (ATFuc,cur) in dependence of a confidence measure, wherein the confidence measure is related to current values of the M electric input signals,
determine a resulting acoustic transfer function vector (ATF*) in dependence of the unconstrained estimate of the current acoustic transfer function vector (ATFuc,cur), and
provide the processed signal in dependence of the resulting acoustic transfer function vector (ATF*).
