摘要

The arrangement (1) has a sound producer (3) for producing a test sound depending on a test signal, where the test sound corresponds to the test signal. A support structure (2) is connected with the sound producer. The support structure retains the sound producer spaced apart from an ear point (32) and is provided for treatment in such a manner that the support structure receives the test sound produced by the sound producer and another sound with a directional component varied at the test sound, in the ear point.
