SUMMARY
A car traveling at Mach 2, which is twice the speed of sound, will allow the driver to hear the stereo system inside the vehicle. The key factor is that the air within the car remains stationary relative to both the speakers and the listener, enabling sound to travel normally. External sounds, however, will not be audible due to the high speed, but internal sound production is unaffected by the car's velocity. Thus, the driver can enjoy the stereo regardless of the car's speed.
