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.
I find it interesting that you can use noise to block noise. Since I haven't heard this gadget, I'm not sure whether the generated noise would be as irratating as the noise being blocked. Apparently it isn't.
I found this device to be quite interested as well. I tell my Electrical Engineering Tech students that in the world of high tech microcontrollers and embedded software, the Common Emitter Amplifier will always have a place in our society. These device just illustrated my student comment.
Fun little project but I have a different application. My husband loves white noise. He falls asleep very easily to the noise of a vaccuum cleaner or the dryer. My biggest problem would be if using this project for noise cancelling that hubby would fall asleep...but in his case it would be a great all natural solution to insomnia...
I guess everyone is different, far911. We have an air filter in our bedroom that also generates white noise and becomes louder when the filter starts to get clogged. It keeps me awake but puts hubby to sleep. I would much rather fall asleep to some relaxing soft music but white noise is very distracting to me.
