Augmented reality (AR) is an enhanced version of the real physical world that is achieved through digital visual elements, sound, or other sensory stimuli delivered via technology. Augmented Music is an enhanced version of music achieved by adding a new modality to improve its experience.

Associate Professor Jeremy Marozeau collaborates with two swiss musicians to create art installations to provide people with a handicap a richer music experience. Under his supervision, three master students in acoustics have designed and built the first two installations at DTU Skylab. This installation is now permanently exposed at the Museum of Art and History in Geneva.

Within the project 'Augmented Music', Associate Professor Jeremy Marozeau from the Hearing Systems section DTU Health Tech collaborates with two swiss artists. Their goal is to create an art installation that allows people with a handicap to regain a full experience of Music through vibrations.

In October 2020, the first
exhibition was created during the "inclusion week" of the Museum of Art and History in Geneva. For 20 minutes, the audience could sit or lay down on a podium equipped with powerful tactors (vibrating transducers) and listen and feel different artists' live concerts. This experience was a clear success and received much positive feedback from the audience, the museum and the press. Based on this first success, it was decided that a live show should be performed at the Museum every month in 2022 using new installations developed at DTU. After each concert, the feedback from the audience will provide some guidelines for the next prototypes. This process will showcase how each new prototype is improved based on newly accumulated knowledge. The first concert was planned to take place on January 20 (if the Corona situation allows it) using the podiums of the first exhibition and two new chairs built at DTU Skylab developer hall by students from the Master of Engineering Acoustics: Brent Reissman, Tomer Tchelet and Gabriele Ravizza.The first prototype is designed to convey the low and mid frequencies to different body parts.The second decouples the vibrations from the structure supporting the body to increase frequency selectivity and decrease vibration damping by the user's weight. Additionally, sympathetic bars transmit the vibrations directly to the users. This mechanism was inspired by the basilar membrane that decomposes the sound into filter bands before activating individual nerve fibers.

On December 7, 2021, the prototypes were shown to the audience in DTU Skylab where everybody could try it out and feel the music and vibrations before the chair was sent on to Geneva. The two chairs are now exposed in the most prestigious room of the museum. In 2022, Jeremy Marozeau and his team are planning to build three new prototypes based on the feedback from the first concerts.
