Abstract (en)
A method of matching a hearing aid antenna in a hearing aid in accordance with a detected signal strength of a received communications signal is provided. The hearing aid having a first hearing aid (121) to be positioned at one ear of a user, the method comprising receiving the communications signal by a wireless communications unit (131) in the first hearing aid (121) or in a hearing aid accessory or in a hearing aid fitting system, detecting a signal strength of the received communications signal and control a matching mechanism positioned in the first hearing aid (121) to obtain optimized antenna reception and/or transmission according to the detected signal strength. The antenna reception/transmission is configured for operation at a frequency of at least 800 MHz.
