A piece played through speakers hanging in a vacuum chamber. As an acoustic conductor is missing, sound waves do not propagate, and, consequently, the composition is inaudible. In such conditions, sound can only be experienced visually, based on the movements of the speakers and the deflection of the decibel metre pointers. In this way, the definition of a musical composition as a phonic work is negated, as is the identity of a music piece turned mute sound sculpture.
The title 340.3 refers to the velocity of sound propagation in the air (as expressed in metres per second), which is missing in the installation.
