When I used to live near LBA
when I was a kid, I could tell the sound of just about everything that used to fly in there from the sound of the engines. Back in those days though alot of the a/c were early turbo props or early jets like the 732/1-11/DC-9 so were quite distinctive.
These days even though I work at LHR
, I find it more difficult to tell a/c apart. Since the engines keep on getting quieter it gets harder and harder, though I can usually tell when it's an A320/321/319 as opposed to a 733/4/5/6/7/8/9.
I do however love the sound of the Rolls Royce RB
-211 on startup. That is such a great sound especially on a wet start !!.
