Most airliners dont go supersonic because they have to change course and deviate in altitude alot of the time.

The reason airliners don't go supersonic is because they can't and not because they have to change course a lot. Transatlantic airliners don't turn a lot enroute.

The sounlevel in the f-16 is extremely high when you don't have the helmet on. I once had the engine started without any earprotection and that really hurt my ears. Even with the helmet on a lot of guys wear earplugs in order not to get too much noise. The noise though is mainly engine & ECS (Environmental Control System) related and not so much airnoise. With the helmet on the noise is a lot more pleasant than what you find in a small propaircraft.
