The centerpiece of the new Center for Black Literature & Culture at the Indianapolis Public Library (IPL) is an impressive multi-sensory, tunnel-shaped walk-through exhibit, right in the middle of the West Reading Room, aptly dubbed “The Epicenter”. The library curator turned to Audio Spotlight integrator
The Exhibit House to devise an audio solution that would not disturb patrons in other areas.
The speakers play biographical narratives from key black historic figures, fed from touchscreen videos along the corridor, and the exhibit also includes books promoting these figures. The exhibit’s corridor shape promotes a journey through history, punctuated by interactive visual elements as well as the audio narratives, without disturbing the surrounding area.
“The AS-168i proved to be the most discreet and flexible directional speaker available. The Audio Spotlight products provide our company a great value, allowing us to add an audio component to displays that are typically visual-only designs.”
– Project Manager Erik Hardebeck, The Exhibit House
Many of the world’s leading libraries have adopted Audio Spotlight technology to provide audio narratives to patrons in a sound-sensitive environment without the encumbrance or unsafe tether of headphones. For use in libraries – or any other similar settings – the Audio Spotlight directional speaker is effectively a singular full-featured device requiring no external equipment or wiring, ensuring that any exhibit has its own isolated audio, while the surrounding area is kept peacefully quiet.
AUDIO SPOTLIGHT IN ACTION
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. Holosonics is a proud partner in enhancing the experience of this library exhibit.
