Is there a way in which you can tell an airbus to a boeing just by the sound of their engines? I know it must depend on what manufacturerer the engine comes from, but I was always under the impression that all A320 have a more high pitched whining noise, from hearing them on takeoffs than the boeings ive heard on takeoff.
Does it just depend on the engine manufacture, or is there a general difference in sound between aircraft engines? (im talking commercial aircraft, not a PA-28 compared to a 747!!)

Remember that one aircraft type can have different available engine variants and these do sound different too.
So you might be on a 767-300, but that could have Rolls Royce Engines (like British Airways), General Electric Engines (like Britannia) or Pratt & Whitney Engines (like United). These will all sound different from one another.
Likewise on the A320 you could have General Electric CFM-56 engines or International Aero Engines V2500s, and these don't sound the same. The V2500 is what I call the "lawnmower" sound!!
So it's not as simple as "a 767 sounds like this" and "an A320 sounds like that".
I used to love the smell of Jet-A in the morning...

For me the easiest aircraft types to identify are the A320 and the 767. My house is situated underneath the flightpath and whenever a QF 767-300 goes over or an Ansett A320 used to go over i could tell straight away what type it was. The A320 makes a really distinct sound, especially when heard from front-on as it's coming towards you.

I noticed that too. The A320/319/321 have a wierd sort of hum, and also the CRJ has its own special sound. I have not watched a 767 take off from close to a fence lately but back when I did I remember how unusually quiet they were. I mean, once they spool up and start moving its like you barely hear them. Not so with the MD80 and 737! The MD80/Dc9 has a sort of crackle in the thunderous exhaust.

I don't know if it works that well with jets, but learning the engine noises of piston powered aircraft passing overhead and identifing them as freind or foe was taught to observers are warning station attendents during the war.
I think even the Boy Scouts had a merit badge in it.

First off, I usually listen to a big engines' hum and the fan beating sound (buzzzz -- or stand in front of your home fan for a sample). This doesn't apply to CRJs
The CRJ has a distinct sound...it can closely relate to someone whistling...or in cartoon shows where ACME bombs are dropped onto the enemy (eeeeeeeeeeoooooooooouuuuuuuu)
I was spotting in Los Angeles looking at small and mid-bodies land (Boeings especially). A Korean Airlines 747 came in with this "I'm a big bad boy" whine that carries a lower pitch than the smallbodied Boeings that I saw.

I can tell the difference between planes flying over my house with out looking at them - a BA 777's engine has a whirring sound when flying over and the larger aircraft have a really low noise and sounds like it is struggling in to the air. A 737 is also pretty obvious, same as the 757.

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 !!.
