In his small scale test (which I admit is far from perfect at isolating sources of sound), he shows that both ICE and electric cars are both way louder than bikes. And both types of cars still have extremely loud horns. His thesis is that high background noise of cities makes people agitated and make cities uncomfortable places to live. So, yes, while electric cars do have no engine noise they still contribute massively to noise pollution and that awful constant hum of tires that engulf cities.
