ABSTRACT:
It should be possible to balance microphones and hearing apparatus more reliably. To this end, provision is made for a method for checking a measuring situation, wherein at least two measurement points of a frequency response of the hearing apparatus are recorded. A check then establishes whether the at least two measurement points lie in a predetermined tolerance range above a threshold. If this is the case, an OK signal is output. Otherwise, if at least one of the measurement points lies outside the tolerance range, the position of the measurement point outside the tolerance range is ascertained and a fault signal is output depending on the ascertained position. It is therefore possible to establish, for example, whether a measuring chamber lacks proofness, a microphone is blocked or the microphone is completely malfunctioning.
