What Will the Nissan Leaf EV Sound Like?

We often take for granted that we can hear a car when it’s coming our way — the familiar roar of the gasoline-powered engine notifies us of an impending collision. But electric cars  are eerily — and dangerously — silent. Nissan’s solution for its upcoming Leaf  EV: adding a complex synthesized sound system for pedestrian safety.
The system, which consists of a synthesizer on the dashboard and a speaker under the hood, turns on as the car starts. It is loudest right after the vehicle turns on (as a warning to surrounding pedestrians) and it turns off automatically above 18 mph. The sound is, according to CNET , “a sine wave sweeping from 2.5kHz to 600Hz,” that is designed to be heard by people of all ages. When backing up, the Leaf generates a sound much like a truck’s beeping as it backs up.
We don’t have a sound clip of the safety system, unfortunately, but Leaf  customers will get to experience it firsthand when the car goes on sale in December.
