The ultrasonic transmitters would allow the user to control exactly where the sound emerges from the billions of points along the path of the signal
By having the signal originate at a single node and directing it into a dish, the node's relative position to the focal point of the dish determines the spread of the sound
The Klang Ultrasonic Speakers would allow a user to focus sound so it could be restricted to just one listener or opened up to a whole room
The technology for Klang was inspired by inventor Woody Norris
The Klang speaker concept proposes using ultrasound to direct and focus audio only where it's required
Rather than sound being pumped out from a loudspeaker in all directions, the Klang speaker concept proposes using a low level ultrasound to direct the audio only where it's required, leaving silence everywhere else. Such a system might allow audio output from a television to be sent to a different place in a room to sound from a hi-fi, allowing each listener to enjoy the experience without inconveniencing the other.
