Evaluation device and method for analysing a public address system, and public address system

Abstract

The invention relates to an evaluation device (6) for analysing a public address system (1), the public address system (1) comprising at least one loudspeaker (3a-3d) and at least one audio signal output unit (4), the loudspeaker (3a-3d) having an impedance plot (10), the evaluation device (6) comprising a neural network (11), the neural network (11) being trained to determine a loudspeaker type on the basis of an impedance plot (10), the evaluation device (4) being provided with the impedance plot (10) of the loudspeaker (3a-3d) and an additional parameter, and the evaluation device being designed to analyse the loudspeaker (3a-3d) and/or determine the loudspeaker type by means of the neural network (11) on the basis of the provided impedance plot (10) and the additional parameter.
