Crepitorio is the irregular succession of two different noises . Noise1 is understandable, the one that our attention seeks. Noise2 is a resonant silence, simulator of the void, the one that our attention unnoticed.
Example A: When a video stops, because it fails, then continue and then it stops again. Noise1 is the video-information, what we try to watch. Noise2 is the freezing of the screen, which returns the resonance of the apparently irrelevance of the space where we are.
Example B: Our regular vision is a constant crepitorio, by opening and closing the eyes, the vision alterns between the external reality (Noise1) and the pink underside of the eyelids (Noise2).
