But no one knows if the noises actually keep pedestrians safe.
Oh So Quiet
That's why, starting on July 1, the European Union will require automakers to fit their EVs with systems that emit warning noises when the car is moving at a slow speed — fake engine noises, essentially. The only problem: no one actually knows whether the systems will keep pedestrians safe.
Under the new EU legislation, automakers must equip any EV with four or more wheels with an Acoustic Vehicle Alert System (AVAS).
This system must emit a continuous noise of at least 56 decibels any time the car is moving 20 kilometers per hour (12 miles per hour) or slower. That's about as loud as a conversation you might have in your home.
Several EV makers already equip their cars with such systems, but this legislation will make AVASs a requirement.
A similar initiative is already in the works in the United States, but according to a New Atlas story, researchers aren't actually certain that AVASs prevent unwanted collisions between EVs and pedestrians.
