Hearing device comprising an acoustic event detector

A hearing device configured to be located at or in an ear, or to be fully or partially implanted in the head at an ear, of a user, the hearing device comprising:

• an input unit providing a multitude of electric input signals representing sound in an environment of the user;
• an output unit for providing stimuli perceivable to the user as sound based on said electric input signals or a processed version thereof;
• an adaptive beamformer filtering unit connected to said input unit and to said output unit, and configured to provide a spatially filtered signal based on said multitude of electric input signals and an adaptively updated adaptation factor β(k), where k is a frequency index;
• and
• a memory, wherein A) a reference value REF, equal to or dependent on a value, βov(k), of said adaptation factor β(k) determined when a voice of the user is present, is stored, or wherein B) a set of parameters for classification based on logistic regression or a neural network, is stored;
• and
• an own voice detector configured to provide an estimate of whether or not, or with what probability, a given input sound originates from the voice of the user, and wherein said estimate, termed the own voice indicator, is dependent on a) a current value of said adaptation factor β(k) and said reference value REF, or on b) said set of parameters for classification based on logistic regression or a neural network, respectively.
