It depends on a few factors... altitude, speed, engine type, and the weather...
the plane is a good bird to fly in... offers full size seats (albeit they don't "recline", they are at a good angle). They are also one of the few commuter planes that offer ALL of the following: overhead bins, tray tables, arm rest on each side of the seat, individual air / light controls, and oxygen masks that drop from the ceiling. The plane also has a full galley and lavatory.
Sometimes the older birds do make sounds and are a bit louder, it's bearable and not overly annoying. Row 8 (on the right) offers the best legroom of any seat imagineable (unless you are flying in a flying-bed on United or BA!)
