Laurie Anderson, installation view of Handphone Table, a sound installation working through bone conduction, MOMA, 1978.
From the press release:
…Handphone Table consists of a simple five-foot-long wooden table with a concealed sound system heard only by becoming actively involved in the work… The viewer hears Handphone Table only while seated, elbows making contact with particular points of the table top and hands covering the ears. The viewer’s arms serve as conductors for the otherwise inaudible sound, which consists of vocal tones at one end of the table and instrumental music on the other.
