Holosonics’ Audio Spotlight Technology Was Featured in The Henry Ford’s Innovation Nation on CBS Television

Audio Spotlight technology was recently featured on The Henry Ford’s Innovation Nation television program. Audio Spotlight directional speaker technology, which has been featured previously on many network TV shows in the U.S. and beyond, produces narrow beams of sound, similar to beams of light from a flashlight.

The crew from Innovation Nation filmed the segment in and around Holosonics’ headquarters in Watertown, MA. During the video shoot, correspondent Alie Ward positioned herself directly in front of an Audio Spotlight speaker and she was visibly astounded and excited as she was filmed stepping into and out of the directional speaker’s narrow beam of sound. The episode on Innovation Nation, hosted by Mo Rocca, was titled “Sound Tunnels”.


The Audio Spotlight system creates focused beams of sound by using a narrow beam of ultrasound as a “virtual” sound source. While ultrasound itself is outside the range of human hearing, this innovative technique causes the air to change the ultrasound’s “shape” as it travels. This change leads to the creation of clear sound that can be directed to a precise location, with directivity and control that far exceeds traditional loudspeakers. This directional audio technology is regularly used for enhancing a wide variety of commercial applications including libraries, museums and galleries, digital signage, retail displays, trade exhibits, and art installations around the world.
