Play enough noise, and the system will explode into fire...
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.
Not to people outside your truck though..
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.

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?
And yes. Mostly luxury cars ATM but it’s growing.
Is this a heat engine? Feels like it has to be obeying the laws of thermodynamics and something has to get hot managing the pressure wave density in air. I'm guessing the speaker magnets and coils heat up. Play enough noise, and the system will explode into fire...

>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?
The skin around ears have been super sensitive due to what I assume is just the natural heat build up from wearing headphones and pressure on skin not used to having pressure on it all the time. The skin is raw and irritated.
It's not terrible, but not comfortable for sure and has been limiting how much I can wear any over the ear or even on the ear headphones.
