A dialog (in speech and sign) between artists, designers, scientists, students, speakers, and signers. Participants touch on the range of human experience including deafness, and on acoustical engineering, especially resonance and sonic vibrations. All presentations are interpreted in American Sign Language. At the center of the conference is a specially-built raised floor, designed to be activated with low-frequency vibration. By sitting, standing, lying on the floor, hearing and deaf participants are able to experience sound through their bodies. During the conference, presenters use the floor as a vehicle for tactile communication.
