Abstract
A head protection device, e.g., a gas mask or a safety helmet, has a communication interface for sending a first communication signal and for receiving a second communication signal. Further, the gas mask has a signal processor providing an interface for sending the first communication signal, for detecting a microphone signal, for detecting the second communication signal and for sending an ear speaker signal. The signal processor is configured such that the first communication signal is sent as a function of the microphone signal, and that the ear speaker signal is further sent as a function of the second communication signal.
