1. Airliners dont have to change course that much in a horizontal way, I meant they have to change altitude in order to avoid other flight's, they will sometimes deviate if there is on-comming traffic and also weather factors come into play when avoiding a thunderstorm for saftey reasons etc.

2. It is a bit strange that you mention it is loud inside the cockpit Run, not because I doubt you but because the engine is further back than where the pilot is sitting. ---snip]

add 1. Having to change altitude is not a big problem even when supersonic. The only reason they don't fly supersonic is because they can't. If they could they would ofcourse only be able to over water because of noise.

add 2. A little trick question for you: Where in relation to the engine do you think the noiselevel is highest on an f-16 ? Standing in front of the aircraft or behind ?

I'll go ahead and give you the answer. There is a lot more noise comming from the intake than the exhaust. So it is more noisy in front of the aircraft.
