prepared circuits, transducers, framesstudy about asynchronous acoustic pulse patterns and material reaction to sound pressure. three pulse-generator circuits are disposed in vertical distribution on frames to represent the pulse in the time domain. the circuits generate periodic pulses at different frequencies, creating irregular patterns through an asynchronous overlapping of regular pattern layers. the frame is the material through which sound is diffused, its dimension change the pulse timbres. the length of the frame is directly proportional to the pulsation frequencies, it's a representation of the time domain.
