Why Crafting the Perfect EV Sound Is Trickier Than You Think

As electric vehicles replace gas-powered cars, a critical safety issue remains: they’re nearly silent at low speeds, posing a risk to pedestrians, especially those with visual impairments.

But designing these sounds is far more complex than it seems, involving a delicate balance of acoustics, human perception, and regulatory compliance.
