Periodic noise



 

The Niagara Falls. This gif is from a webcam site by www.icnc.org. Click to go there. You know what noise sounds like? If not, click on the headphone icon to the right. You'll get one of the finest samples of digitally generated white noise. No, it's not the Niagara Falls. It's more perfect: it's digital. Please use headphones. Mediocre PC speakers might spoil the effect.

O.k., white noise sounds just boring. Periodic noise sounds different. Yet it is the same noise, only presented cyclically (details see FAQ). Warning: Listening to periodic noise stimuli is dangerous to your health and may cause addiction and mania.
