Abstract
A hearing aid system may include a behind-the-ear (BTE) part configured to be located at an ear of a user, an in-the-ear (ITE) part configured to be located in an ear canal of a user, and a measurement circuit. The ITE part may include a receiver for converting an electric output signal having frequencies in the human audible frequency range to an output sound, and a resistive identification element. The measurement circuit is configured to measure an identification parameter indicative of the resistance of the resistive identification element, thus identifying the ITE part. The measurement circuit uses the same electric output signal that is driving the receiver to determine the identification parameter. Advantageously, this approach does not require an additional signal, such as DC voltage, to determine the identification parameter.
