In this chapter, I explore the idea of noise as useless (perceptual) information, focusing especially on the relationship between perceptual configuration (temporal interplay, intersensory relations) and action (tool use, affordances). I do so building on Heidegger’s view of perceptual experience as involving indications and relations of handiness. I argue that noise is a disturbance of the unity of perceptual experience as informative about the affordances of things and places, and thus it affects the flow and unity of experience as action. I suggest that unlike broken tools, with noise the spotlight is on perception and on our role as agents who can and must act on how we perceive. I then explore some deeper ties between action and perception, arguing that the absence of (or deficiencies in) agency can result in perceptual contents lacking any order or structure in terms of which things are meant to be grasped properly, therefore generating some noisy experiences. I thus look into ‘alien tools’ and artefacts to emphasize some positive implications of noise as useless perceptual features that afford exploring new possibilities of perceptual configurations and reshaping the boundaries between noise and information.
