Too much of a good thing

I can't sleep because it's too quiet.

It's a never-ending quest for peace and solitude on a tiny island inhabited by millions of people, but sometimes, there are nights that are inexplicably silent.  Sirens, jack-hammers, trucks barreling over those giant steel plates in the street (ka-thunk, ka-thunk, ka-thunk) all have explanations.  But, quiet...now, that's a mystery.
