Microtonal Wall is a sonic installation featuring 1,500 speakers. It is the largest work to date by artist and composer Tristan Perich, who created the piece to explore 1-bit noise and pitch. An accumulation of mathematically derived frequencies fills the surface of the sculpture, which behaves as white noise when experienced at a distance. Upon close range, the musical sensation of pitch is audible, as each speaker rings with a distinct frequency.
