An Audio Frequency Induction Loop receiving device, an Audio Frequency Induction Loop transmitting device, a system and a method for alerting a person with impaired hearing about a moving vehicle are disclosed. The Audio Frequency Induction Loop receiving device comprises an Audio Frequency Induction Loop receiver and a processing circuitry. The Audio Frequency Induction Loop receiver is configured to receive a signal via a magnetic field generated by the Audio Frequency Induction Loop transmitting device installed in the vehicle. The processing circuitry is configured to cause the Audio Frequency Induction Loop receiving device to detect the magnetic field generated by the Audio Frequency Induction Loop transmitting device and generate an alert signal for alerting about the moving vehicle.
