No, the opposite. If I take a long-haul flight (intercontinental) without using noise-cancelling headphones I'll have increased tinnitus for the next month. That problem is greatly reduced if I use the headphones. When that's said, the newer planes like e.g. the Airbus A350, if your're sitting in a reasonably good spot, has vastly less noise than the ones I used to fly in the past (747, for example).
