I would think having a vehicle be entirely electric must allow more options in terms of car body shape and even tyre shape/material that could possible reduce noise (and particulate) pollution even further. And certainly if we could reduce the vehicle weight (I gather the current generation of EVs typically weigh 25%+ more than their ICE equivalents - and cars have generally been getting heavier over the last couple of decades anyway, which is a trend that we desperately need to reverse, and won't happen without legislation). Having said that, as a cyclist the idea of not being able to hear cars around me is somewhat disconcerting.

I have no trouble hearing EVs approaching, they sound identical to modern ICE, which is to say 90% road noise.

Some ICE cars are noisier by choice of course but modern commuter cars are very quiet at the exhaust typically, the road noise is the dominant noise.

I have cars driving past me at about 50kph right now, I am barely hearing the engine for about 3 seconds or less as it passes, and the road noise continues to be audible for about 20-30 seconds. Pretty much all I am hearing is road noise. Same was true when I lived near a highway. Just a whooshing blob of road noise.

Driving both a gasoline car and an EV, I can surely tell you that pedestrians get out of the way when I approach with the former much more often than with the latter. So they are no identical. Of course where I live there's no law-mandated minimum noise level for EVs.
We might end up in the weeds here, but I imagine you are meaning when moving relatively slowly? I hope pedestrians aren't in need of moving out of the way of your driving over 25kmph!

Indeed at slow speeds EVs are quieter. That probably does make a difference for inner city traffic, which is also where you really want less tailpipe emissions, EVs help there too.
