Electric cars are known for being quiet — sometimes surprisingly quiet.
While this helps reduce noise pollution, it has also raised concerns about pedestrian safety, particularly for visually impaired people, cyclists, and anyone crossing busy roads.
As a result, regulations now require most new electric and hybrid vehicles to produce artificial warning sounds at lower speeds.
But should electric cars really be forced to make noise, or does it undermine one of the biggest benefits of EV ownership?

Why Are Electric Cars So Quiet?
Unlike petrol or diesel vehicles, electric cars do not use traditional combustion engines.
That means they produce:
- Less engine vibration
- Minimal idling noise
- Much quieter acceleration
At higher speeds, tyre and wind noise become more noticeable, but at low speeds many EVs can be almost silent.
While drivers often enjoy the quieter experience, it can create problems for pedestrians who rely on sound to detect approaching vehicles.
Why Electric Cars Now Have Artificial Sounds
To improve road safety, governments introduced regulations requiring electric and hybrid vehicles to emit warning sounds at low speeds.
In the UK and Europe, most new EVs must include an:
Acoustic Vehicle Alerting System (AVAS)
These systems automatically generate sound when travelling at lower speeds, usually below around 12mph.
The purpose is simple:
- Help pedestrians hear approaching vehicles
- Reduce accidents in urban areas
- Improve awareness for visually impaired people
- Increase cyclist and pedestrian safety
The sound is designed to be noticeable without becoming excessively loud.
Safety Concerns Around Silent Cars
One of the main arguments in favour of artificial EV sounds is safety.
Research has shown that quieter vehicles can be harder to detect in:
- Car parks
- Residential streets
- Busy urban areas
- Junctions and crossings
Pedestrians often hear vehicles before seeing them, especially in poor visibility or crowded environments.
Artificial sounds help close that safety gap without removing the environmental benefits of electric vehicles.

Do Artificial EV Sounds Feel Fake?
Not everyone loves the idea of synthetic engine sounds.
Some drivers and enthusiasts argue that:
- Artificial noise feels unnecessary
- Fake engine sounds lack authenticity
- Quietness is part of EV appeal
Others believe manufacturers should embrace creativity and design futuristic sounds instead of trying to imitate petrol engines.
Several car brands have already experimented with:
- Sci-fi inspired sounds
- Futuristic acceleration tones
- Customisable sound profiles
As EV adoption grows, vehicle sound design could become an important part of brand identity.
Will Electric Cars Get Louder in Future?
Probably not significantly louder — but smarter.
Manufacturers are increasingly focused on:
- Safety-compliant warning systems
- Adjustable pedestrian alerts
- Reduced urban noise pollution
- Improved sound direction technology
The goal is to balance pedestrian safety with the quieter driving experience EV owners enjoy.

Key Takeaway
Electric cars may be quieter, but safety concerns mean artificial warning sounds are now a necessary part of modern EV design.
While opinions differ on whether synthetic noises improve or reduce the EV experience, the main priority remains keeping roads safe for everyone.
