The present invention relates to a pressure-difference warning system comprising an acoustic signal device, comprising an energy supply device and comprising a pressure sensor. The pressure sensor is designed for measuring a pressure difference between an interior region and an exterior region. The energy supply device is designed for providing energy for operating the warning system. The acoustic signal device is designed for outputting an acoustic signal if the measured pressure difference exceeds a specifiable threshold value.
