William Grill had a problem with noise distraction at home. Over the summer, vacationing visitors provided a wealth of noise that needed to be dampened. To solve the problem, Grill added some noise of his own -- continuous static noise to drown out the distraction.
His small, inexpensive random noise generator produces digital noise, which has the advantages of being easily repeatable, free of calibration, and inexpensive to produce. This offering runs on batteries and can be used with headphones as a noise mask to eliminate the sounds of rowdy gamers, crying babies, and gossiping grandmas.
