A system comprises a microphone array and a processor. The microphone array detects first sound signal and the second sound signal. Each of the first and second sound signals has a particular frequency band. Each of the first and second sound signals is originated from a particular sound source. The processor receives the first and second sound signals. The processor amplifies the first sound signals, each with a different amplification order. The processor disregards the second sound signal, where the second sound signal includes interference noise signals. The processor determines that the first sound signals indicate that a vehicle is within a threshold distance from an autonomous vehicle and traveling in a direction toward the autonomous vehicle. In response, the processor instructs the autonomous vehicle to perform a minimal risk condition operation. The minimal risk condition operation includes pulling over or stopping the autonomous vehicle.
