Abstract
The size of measuring boxes for hearing apparatuses and in particular for hearing devices is to be reduced, with the efficiency of the measuring box in respect of attenuating interference noises being maintained or improved. A measuring box is thus proposed, which comprises an interference signal recording facility for recording an interference signal. Furthermore, provision is made in the measuring box for a signal generating facility to generate a compensation signal which is phase-opposed to the recorded interference signal, so that the interference signal can be compensated for by the compensation signal. The interference noise attenuation is thus achieved here by an electronic active part, so that the quality demands on the measurement space can be reduced and its size thereby decreased as well.
