We all remember from high school, what is the interference - the sound waves crash into the object, bend around it, and then bump into each other, creating a different sound on the other side of the obstacle. Today, scientists argue that possible was the creation of sound ' cloak ', when the waves passing through the barrier, neutralize each other. At the moment, such a phenomenon is possible theoretically, but the current project in the Duke University say they have developed technology to create an acoustic material that would allow any object to be invisible for acoustic instruments.
When designing a concert hall skillful handling of this effect could be greatly improved sound anything was. Equally important would be to use this phenomenon and for submarines. Oh, and the bats would not like it at all. Interesting would be the possibility of using this technology on an individual basis. It is possible that all these possibilities are limitless!.
