Summary:Process for forming a group signal of a directional characteristic of a transducer arrangement (10) consisting of a group of commonly operated electroacoustic transducers (11) arranged on a curved support (12) comprises time-delaying electrical receiving signals on the transducers at sound pick-up and adding to the group signal. The delay times of the receiving signals are repeatedly increased and reduced and the delayed receiving signals are added to the group signal until a maximum value of a variable of the group signal is reached.
