Tactical Uses Of A Belief In The Unseen (2)

Deborah Stratman's installation Tactical Uses Of A Belief In The Unseen (2) is both a created landscape and a speaker.  It uses a multifaceted sound collage consisting of explosions, earthquake frequencies, helicopters and other heavy equipment to suggest sounds of military action.  Coming from the floor, these low frequency sounds are more felt than heard.  There's also a moving beam of sound broadcast from the ceiling emitting sounds of sirens.  It is audible only when pointed directly at the listener.  Like cinemas, Stratman's designed soundscape provokes belief in an unseen material world.
