Back when I was living in manhattan (20 yrs ago), I switched my windows to double windows, each sliding left-right on its own.
It had roughly 1" separation -- a lot better than these windows today that have maybe .25" separation!
As with you, the noise reduction was incredible -- it just disappeared.
But soon I started hearing noises again!
Different noises, though.
Water flowing through the pipes, pin-drops from upstairs, etc.
What do they say, there's no free lunch?

PS: In winter, it sure was now one hell of a lot warmer!
