MIT researcher Joe Pompei’s revolutionary Audio Spotlight focuses sound waves and allows users to direct sound
Imagine being able to send a sound to a single person or location. MIT researcher, Joe Pompei, has created a way to make that possibility a reality through a new technology that directs and controls sound waves. Traditional speakers transmit non-directed sound at wavelengths of several feet. Pompei’s Audio Spotlight transmits millimeter-sized, ultrasonic waves in a very narrow beam of sound, which becomes audible as it travels through the air. These new waves can travel much further, and more focused, than normal sound waves. With the Audio Spotlight, sound can be controlled with the same precision as light.
