Manually held external transmitting coils are used for standardized testing of hearing aids by means of a test box. Measurements using the hearing aid telephone coil are therefore cumbersome and difficult. There is therefore proposed a holder module connected both electrically and mechanically to the test box and having a receptacle for holding the hearing aid, a transmitting coil for producing an electromagnetic signal detectable by the hearing aid and with connecting means for electrically connecting the transmitting coil and a coupler connected to the hearing aid during measurement to the test box.
