Abstract: The disclosure presents a method and an amplifier system for minimizing variation in an acoustical signal caused by variation in gain of an amplifier, comprising a battery for providing a supply voltage to the amplifier, a digital signal processor for providing the acoustical signal to the amplifier, a controller unit receiving an enablement signal when the supply voltage is in an offset mode, and based on the enablement signal requesting a measured voltage during a time period, and a first analog-to-digital converter configured for measuring the supply voltage to the amplifier when receiving the request from the controller unit or the first analog-to-digital converter is configured for measuring the supply voltage to the amplifier continuously, and where variations in the measured voltage relates to variations in the supply voltage during the time period. Furthermore, the controller unit is configured to predict offset modes (i.e. changes) in the supply voltage based on the enablement signals and a fitting of the measured voltages, and wherein the controller unit is configured to generate a compensating signal based on the fitting and transmit the compensating signal to the digital signal processor, the digital signal processor is then configured to minimize variation in the acoustical signal at the output of the amplifier by compensating the variation in gain of the amplifier based on the compensating signal.

Abstract: There is provided a hearing aid with an antenna connected to a transmission and/or reception circuit for transmission and/or reception of the electromagnetic energy via the antenna. A coupling circuit, e.g. including a directional coupler, is configured to sense an electric return power from the antenna, and to generate a power signal based on the sensed electric return power. A controllable impedance circuit is connected to the antenna, so as to allow adjusting of impedance of the antenna in at least two different steps. A processor is configured to generate a tuning control signal to the controllable impedance circuit in response to the power signal. This allows control of the impedance of the antenna for minimizing impedance mismatch, and thus improve performance of the antenna by tuning the impedance to the operating conditions of the antenna, preferably in an automatic manner.
