It does vary depending on the manufacturer. Some are pretty quiet. I can't hear any Tesla "honking at low volume" when they pass by, but they probably just don't comply with new regulations. I find Hyundai to be the worst.

I live in a tower at the intersection of a busy street with traffic lights and I can hear the Hyundai EVs while sitting in my couch when the windows are open. In fact, they're open right now and I can clearly hear a Chevrolet EV decelerating before coming to a stop at the traffic light while I'm typing this. Toyota EVs are also pretty loud. Granted I can also hear loud and modified fossil fuel engines but most of them usually blend into a white noise.

When walking around the smaller streets of my neighbourhood, cars are going pretty slow and the noises of Hyundai, Chevrolet and Toyota EVs definitely stand out. It's weird because I'm a pedestrian. I don't have a car. I hate them. And I want them to be secure for pedestrians. But some of those warning systems are so loud and annoying that I wish they would just be quiet.
