> If an impending collision is detected, the vehicle’s sound system plays a short interference signal, which can trigger a reflex, whereby the stapedius muscle in the ears contracts, which alters the link between the eardrum and the inner ear for a split second and better protects the inner ear against high acoustic pressures, which can result from a loud crash.
