Method and acoustic system for determining a direction of a useful signal source
Abstract:
A method determines a direction of a useful signal source in an acoustic system that has a first input transducer and a second input transducer. The first input transducer generates a first input signal from a sound signal from the surroundings and the second input transducer generates a second input signal from the sound signal. The first input signal and the second input signal are used to form a plurality of angle-dependent directional characteristics having a respective fixed central angle and a respective given angular expansion. The signal components pertaining to the individual directional characteristics are examined for the presence of a useful signal from a useful signal source. The applicable central angle is assigned to a useful signal source ascertained in a particular directional characteristic as the direction of the useful signal source.
