white noise / pink noise (circuit)

white noise pink noise (circuit)
2 electronic circuits, speakers, batteries, paint each circuit: 1 h x 3 1/2 w x 2 1/2 inches 2001

This pair of noise generator circuits are painted white and pink, corresponding the definition of sound they are producing. The discrete components remain unpainted, and, with close inspection, the slight differences in values of resistors and capacitors in the filter state of the circuits that produce the variation between white and pink noise can be seen.
