I ran a Soundlab for Graphic and Media Design at the London College of Communication, University of the Arts London. During 4 sessions students experimented with sound in non musical ways discovering the hidden world of sounds around us. They did this with contact microphones that allowed them to listen to sound within materials. We started with a walk discovering what different materials sound like, after this the focus was on collecting materials and building sound instruments that could then be used to play and create sounds. During the sessions students soldered their own contact mics and dipped these in fluid plastic to create lofi hydrophones. By the end each student created a short composition using the sounds they discovered and created with their contact mics.
