Audial Bi-Imagery

Researchers Announce Breakthrough Development in Audio Technology Allows Sound Waves to Carry Two Distinct Audio Signals

The newly developed process, which is called Audial Bi-Imagery, allows the listener to hear one of two completely different sounds depending on how they focus their hearing. The effect is similar to the visual process by which people can see one of two distinctly different patterns in a drawing, such as seeing either two faces or a single goblet, depending on how they focus their vision. - March 30, 2012
