My first thought was that airplanes need noise canceling for the engine sounds. There's a real difference in a long flight with and without noise canceling headphones. Effective (better?) noise cancelation for the whole cabin would be impactful.


It's difficult if not impossible to do active noise cancellation for multiple people simultaneously.
