Hearing device comprising an amplifier system for minimizing variation in an acoustical signal caused by variation in gain of an amplifier

A hearing device comprising:

• an amplifier configured to receive an acoustical signal;
• a battery configured to provide a supply voltage to the amplifier;
• a processor configured to generate a trigger signal associated with the processor performing a processing that causes a drop in the supply voltage, the processor being configured to transmit the trigger signal to a controller configured to receive the trigger signal,
• wherein the controller is configured to generate a compensating signal based on the trigger signal;
• and
• wherein the hearing device is configured to minimize the variation in the acoustical signal by including at least part of the compensating signal into the acoustical signal.

A hearing device comprising:

• an amplifier configured to receive an acoustical signal;
• a battery configured to provide a supply voltage to the amplifier;
• a processor configured to generate an trigger signal when detecting a drop in the supply voltage, the processor being configured to transmit the trigger signal to a controller configured to receive the trigger signal;
• wherein:
• the processor is configured to measure the supply voltage from the battery;
• the processor is configured to, based on the measure of the supply voltage, generate the trigger signal;
• the controller is configured to generate a compensating signal based on an estimation of variation in the supply voltage;
• and
• the hearing device is configured to minimize the variation in the acoustical signal by adjusting the acoustical signal based on the compensating signal.
