The IKO, a twenty-faced loudspeaker system, is treated not as a sound source but as a spatial instrument, inseparable from its surroundings. This practical demonstration activates the IKO in the space itself, showing how sound can shape, inhabit and reconfigure the rooms around us.

A discussion on the Half Life installation between the artists and archivists. T1/2 is a sound installation built from field recordings of the Semipalatinsk Nuclear Test Site in eastern Kazakhstan, where the Soviet Union conducted over 450 nuclear tests between 1949 and 1989. Captured with hydrophones, geophones and contact microphones, the recordings decay in time with the half-lives of radionuclides still present in the ground.

Drawing on extended technologies and durational listening to sounds outside human attention, this informal talk treats listening as a constant questioning of perception, convention and faulty histories.
