mooeypoo Posted June 13, 2008 Share Posted June 13, 2008 Scifi comes to life in this new creation: http://www.engadget.com/2008/06/13/scientists-create-cloak-of-silence-serial-killing-will-neve/ The only thing I thought was a bit disturbing was the title Engadget chose to portray (serial killers.. wonderul). Sounds pretty awesome... but it's not yet developed Also, I was thinking - soundwaves travel through a medium ONLY (air, water, whatever) and do not travel in a vacuum. Won't it be simpler to create a thin layer of vaccuum on the windows, in the walls, and - voila - no sound passing through? The entire 'tubes / meta crystals' angle sounds a bit over-the-top for me.. What do you guys think? Link to comment Share on other sites More sharing options...
john5746 Posted June 13, 2008 Share Posted June 13, 2008 Just offhand, I think it would be pretty costly to create and maintain a vacuum. Then you also have to worry about the vibration of the container itself? Link to comment Share on other sites More sharing options...
