Name First Audio Beam System
Category Science and Technology - Engineering Innovations
Data Info NTU researchers have developed Singapore’s first audio beam system to allow for a very private enjoyment of music and movies. Unlike conventional loudspeakers which send omni-directional sound, the NTU audio beam system, developed in 2004, uses ultrasonic technology to project sound to a very small area. This enables the creation of private listening environments. In a music store many people can test out different CDs without interfering with one another and without using headphones.
