A phonon is the quantum mechanical description of an elementary vibrational motion in which a lattice of atoms or molecules uniformly oscillates at a single frequency.
Nonlinear is a sonic articulation of acoustic and optical phonons, an out of phase or linear movement between atoms. A phonon represents an excited state in the quantum mechanical quantization of the modes of vibration in elastic structures of interacting particles. The installation consists of two latex spheres each containing a lavalier microphone, the spheres are situated between a speaker driver and applied pressure. Electronics apply different amounts of pressure to each sphere causing an amplification of the relationship between manipulated space, microphone, speaker and the surrounding acoustic environment. The pressure applied will determine the characteristics of feedback, creating linear and non linear phase patterns of sound through material and space. The spheres represent out-of-phase movements of l atoms in the lattice, one atom moving to the left, and its neighbour to the right This occurs if the lattice basis consists of two or more atoms.
