Claims11
A communications terminal, comprising:
- a transmitter capsule;
- a receiver capsule;
- an AF amplifier stage, operatively coupled to the transmitter and receiver capsules;
- a gain adjustment stage for varying a gain factor of the AF amplifier stage in order to adjust receiver volume;
- a speech volume detection device operatively coupled to the gain adjustment stage;
- and
- a voltage measurement device as part of the speech volume detection device, the voltage measurement device being associated with the transmitter capsule and having a downstream averaging stage for averaging the detected speech volume, wherein the gain factor of the AF amplifier stage is adjusted as a function of averaged speech volume.
