How Music Composers Are Replacing The Sound Of Engines In Cars

We’re all guilty of this: walking down the street,
staring at our phone, and neglecting our surroundings. Until… you hear a car coming your way. But the cars of the future might sound completely
different, like this: [slow electric whirring] That’s the sound of BMW’s Vision M Next. Which was composed by
Hans Zimmer, one of the most famous movie-score
composers of all time. Or like this: [electric revving] That’s the sound of Volkswagen’s ID.3, which was created by Leslie Mándoki, a composer who played drums in the European disco
band Dschinghis Khan. So, why are these cars
making artificial sounds, and why are automakers
tapping music composers to create them? First off, what do the Vision M Next and ID.3 have in common? Well, they’re electric vehicles, which typically sound like this. [silence] And that can be a problem, since we use our sense of
sound to alert ourselves to oncoming traffic and
other potential dangers. So if you were, say,
distracted by your phone while crossing the street and a noiseless EV was headed your way, you’d be more likely to get hit. In fact, one study shows a hybrid vehicle accelerating on its electric motor is 1.18 times more likely
to hit a pedestrian and 1 1/2 times more
likely to hit a cyclist than a vehicle with an
internal combustion engine. Lawmakers in the US and Europe have passed a new regulation to minimize these risks. The solution is an acoustic
vehicle alerting system, or AVAS, which requires hybrids and EVs to emit a sound that alerts pedestrians and cyclists to their presence. But sound doesn’t only make EVs safer. It’s also a way for
automakers to give their cars a voice, or a sonic identity. Just as a Porsche has
an unmistakable sound, something like Nissan’s Leaf
can now have its own sound, handcrafted by a musical
genius, like Danni Venne, the lead producer and creative director for the Nissan Leaf AVAS tone. Danni Venne: When the project came in, it was framed as, like, “There’s a new regulation in town, and we’re gonna put
sound to the regulation. And I had to kind of turn my head around to think about, if I go to buy a, look for a car, go shopping for a car, when that car rolls in front of me, the way it looks, the way it moves, and the way it sounds is gonna have some sort of emotional impact that’s gonna make you
be like, “I want that.” Narrator: Nissan, like other automakers, wanted to turn its AVAS tone
into a marketing device. Simply put, the AVAS tone would become an audio logo for the Nissan Leaf. And who better to
compose a sound like that than a composer or a
team of people who have studied sound and understand how to use it as a tool to market products? But first, Venne and her
team had to figure out what instruments to use. Venne: That piece of
audio I’m talking about is going to be about two seconds or less, looped. And so two seconds of sound that’s looped has to sound smooth. We experimented with a
wide range of instruments. That said, I wanted to explore what suggests movement
and power and energy. Narrator: Venne and the rest of her team experimented with sound she categorized as pulsating, wavering, and smooth. Pulsating sounds mimic an engine in the way they bounce
up and down abruptly. Wavering sounds are similar,
but are much smoother in the way they bounce between notes. And smooth sounds are, well, smooth, solid tones that don’t
waver or bounce at all. Venne: You really have
to go for instruments that don’t have a hard attack to them. Wind instruments,
flutes, oboes, clarinets. The tone in wood, in wind instruments can be more like this, right? It can kind of waver a bit, have a little wave to them. Narrator: Finding tones
and instruments that work was only the start of
composing the AVAS tone. The sound had to be active. For every kilometer per hour, the tone increases in
pitch and speed by 1%, up to 30 kph, or 18.6 mph. This way, pedestrians and cyclists have an audio cue of
what the car is doing. After 30 kph, there’s
enough wind and road noise to alert pedestrians to a car’s presence. [instrument humming] Danni: This might be a sampled flute. Can’t remember at this point. You can also, I started
blending the pulsing sounds. [instrument pulsing] Some of these pure, organic tones, even though I like them, they ended up sounding a little spooky. You know, a little like ghosts. Some of the smoother ones, like [instrument humming] that… even though this feels
a little bit like… that feels a little bit, to
me, like a vacuum cleaner. Though it did suggest a
certain amount of power. What we found, though,
was we kept moving more towards sounds that
had a pureness to them. And that led us to use a lot of sounds that were synthetic. Even though they might be
warm and rich sounding, but using sounds that
came from the synthesizer and then really manipulating those sounds. Layering them with different
ones, ’cause we could have that complete control and stability. And I think that idea of,
like, control and stability translates, then, emotionally, to, like, good engineering. Narrator: While increasing
in pitch and speed, the sound had to stay within
the required frequency range. Once Venne and her team had a sound that Nissan approved, they used an equalizer
to process the audio, adjusting various frequency
ranges to make sure it met all the requirements
of the regulation. Venne: That’s when it
got to be very difficult to adjust things too much further than where the regulation needed to be. My engineers and mixers were going in with a very fine-tooth comb to just EQ it exactly. And that last stage of it was, I wouldn’t call it creatively inspiring. It was challenging. It
was very challenging. Narrator: Designing an AVAS sound is much more complicated than it seems. The tone is twofold: On one hand, it needs to alert pedestrians and cyclists to a car’s presence to
mitigate collisions. And on the other, it needs
to radiate a pleasant tone, one that will attract people
to the car and the brand.

  1. Go back to gas cars, these electric cars is just a money grab by manufacturers. Electric vehicles are worse for the environment, and co2 isn’t bad for the environment. The more co2 in the air the greener the planet. PLANTS BREATH CO2, CO2 IS A GOOD

  2. What retard looks at their phone while looking at their phone.That’s just natural selection at that point.

  3. It's pretty sad we need to make cars noisier so people don't walk in the street while looking at their phones!

  4. Human flock is spurred to glorify cars meanwhile, it is a perfect reflexion of Human ego, consumption and mass polution. But keep on buying, like, you are actually working your Time on to buy such toys while taking a bike on your traipse is healthier and let you aware of Nature's noises. Startles me the hindrance between technologies & simplicity

  5. If you are not paying any attention and walk in front of traffic that's your own stupidity and we can do without you on the planet

  6. Engine Sounds won't have a future I think. Instead traffic will become much safer by other techniques. Just listening to them shortly puts me in a stressed mood. Imagine driving for hours on end with these howling sounds in the background 🙁 Noise pollution bears negative effects as well… Of course it is less apparent than straight up car crashes though

  7. The girl walking on the side walk, I think that video was taken close to my neighborhood lol. I'm like 99.99% sure.
    Edit: I'm 100% sure now lol.

  8. I want a car that sound like Beyonce

    By Beyonce, I mean my car would be singing "all the single ladies" in a loop when I'm driving.

  9. Is this a song the the car plays or are they engineering the mechanics of the car to create the sound? If it's the former, I'm not interested.

  10. Why are we trying to save people that are too dumb to watch where they are walking instead of their phones? So much for survival of the fittest

  11. Sounds like folks with ti much time on there hands. Was looking forward to a nice quiet neighborhood. Ill show them and tape dog whistle to the front of my car. Enjoy your barking dogs.

  12. I drive an electric car and love how silent it is. If it made artificial noise I would disable it. If a pedestrian walks in front on my car because they’re distracted by their phone that’s their fault.

  13. Or just recreate actual engine sounds and have it linked to the accelerator instead of playing horror themes… just a suggestion
