摘要

The device includes a portable sub-unit, where an information unit is arranged separately from the portable sub-unit. The information unit determines a physical parameter and wirelessly transmits the signal corresponding to the physical parameter to a transmit and/or receiver unit. A control unit outputs an associated signal to an acoustic output unit based on the received signal.
