This TED Talk features sound designer, pianist and composer Renzo Vitale, recorded live at TED-It-Mirk, K-G-A-A-Darmstadt Germany, 2018.

Let's start with silence.

Silence. Silence is one of the most precious condition for humans, because it allows us to feel the depth of our presence.

This is one of the reason why the advent of electric cars has generated lots of enthusiasm among people. For the first time, we could associate the concept of cars

with the experience of silence.

Cars can finally be quiet.

Peace in the streets, a silent revolution in the cities. But silence can also be a problem.

The absence of sound, in fact, when it comes to cars,

it can be quite dangerous.

Think of blind people who can't see a car which is approaching.

And now, if it's electric, they can't even hear it.

Or think of every one of us as we are walking around the city,

we are absorbed in our thoughts,

and we detach from the surroundings.

In these situations,

sound can become our precious companion.

Sound is one of the most wonderful gift of our universe.

Sound is emotion. And sound is sublime.

And when it comes to car, sound is also information.

In order to protect pedestrians and to give an acoustic feedback to the drivers,

governments around the world have introduced several regulations,

which prescribe the presence of a sound for electric vehicles.
