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.
- Anechoic 6y agoIs that noise canceling or is it masking?
- keyle 6y agoThat "sounds" interesting but why not have a partition or a less loud AC Unit?
- gruez 6y agoDo you have a picture of what it looks like? AFAIK room-wide noise cancellation can't work because noise cancellation requires the exact position of the listener to be known, otherwise the sound will not be canceled out and might even be amplified. see this animation: https://en.wikipedia.org/wiki/File:Two_sources_interference.gif https://en.wikipedia.org/wiki/File:Two_sources_interference...., if one of the wave sources is the AC and the other is the noise cancellation machine, only some areas will have no sound, but others will have even louder sound.
- dannyw 6y agoIt’s apparently possible on planes, so it could work for offices too. https://www.flightglobal.com/quiet-revolution/31793.article https://www.flightglobal.com/quiet-revolution/31793.article
