Noise Pollution In Cities (or Countries?)

I’m curious if there’s any data on noise pollution over time in cities, such as NYC, London, Paris, or perhaps even in entire countries (if that even makes sense).

I’m thinking electric cars are becoming more common, and they’re more quiet, so perhaps noise pollution has gone down in recent years?

(To be honest I’d be more interested in a graph than the raw data, but this was the stats/data request sub I found (via askstatistics…) so here I am.)

Thanks!
