I expected them to be put elsewhere in the plane. For instance, my office has a floor with exposed AC units, and "noise-cancelling"[1] machines next to them that remove most of the sound of the AC. I wonder if something similar could be done for planes.

[1] Not sure exactly what the name of this device is.

Is that noise canceling or is it masking?

Always great to see development in this domain. IWAENC and Silentium come to mind as the forefront. I hope one day the researchers will realize that they are trying to cancel the wrong source. Instead of cancelling noise external to the human, the real breakthrough will be to cancel the human voice. This will confer privacy and other benefits in areas of increased population density. I would prefer a smartphone to have a feature like that than an incrementally snazzy camera, for example.

>wearing active noise canceling headphones for extended periods of time can be uncomfortable and even cause injury Does anyone know what type(s) of injury is this referring to, how long is too long and how widespread/likely it is?

I suspect the article is referring to things like bruising from tight fitting earcups or maybe muscle strain from the weight of the headset, not something specifically related to the noise canceling function (except perhaps from excess noise caused by ANC circuit malfunction that might cause a temporary threshold shift)

My new Ram 2500 diesel has active noise canceling and is the quietest ICE vehicle I’ve ever been in. Probably quieter than electric vehicles at high speeds.

Can you switch it off/on to hear the difference? Would be interested to know the difference perceived.

Are there any other cars that do this?
