Two videos and one airplane.
First video the aircraft with winglets and the “pre-NEO” engine. Engine noise at about 30 seconds.
Second video the same aircraft with the “NEO” engine. Engine noise at about 1:30. Drama sound track aside, almost certainly the quietest single aisle Airbus has ever flown. Airbus offers these videos: uncut takeoff and uncut landing – it is very quiet.
Jet engines noise in the first video… and music in the second video…
Here is a comparison made by Pratt and Whitney. They refer to the CSeries, but of course, there is no CSeries without the GTF engine:

That will be some relief from those annoying night flights over Montreal. Especially those at 3 in the morning.
