Abstract: A device includes a gas-measuring unit and a sound-measuring unit. The gas-measuring unit has a gas sensor detecting a first measured variable, and a gas analysis module determining a gas concentration from the first variable and comparing the concentration with a first threshold value, to output a first signal based thereon. The sound-measuring unit has a sound detection unit detecting a second measured variable, and a sound analysis module determining a status variable, from the second variable, indicating a noise exposure, and comparing the status variable with a second threshold value to determine a first parameter indicating a current sound level and/or determining a second parameter indicating a sound exposure accumulated over a time interval. The sound analysis module may determine the status variable, the first parameter and/or the second parameter as a function of the comparison of the gas concentration and the first threshold value.

Abstract: A gas-measuring device includes a control unit, a gas sensor module, a radio receiver unit, a first radio transmitter unit and a second radio transmitter unit. The control unit detects sensor data via the gas sensor module in a first operating state and upon detecting a potential hazardous state, based on the sensor data, changes over into a second operating state. The control unit further detects one or more radio signals, which indicate respective characteristics of respective portable transmitter units, by the radio receiver unit in the second operating state, and determines, on the basis of the radio signals, which of the transmitter units have a sufficiently close proximity in space to the gas-measuring device. The control unit provides the characteristics of the transmitter units, having a sufficiently close proximity in space, via the first radio transmitter unit.
