I don't think it's abstract at all. Rub something sharp (anything from a stick to a phonograph needle) on an object and you'll directly transcribe its spatial frequency spectrum into an audio frequency spectrum.
- canjobear 8mo agoDo you think it's obvious that a chick would understand that connection?
- bondarchuk 7mo agoIt's not about "understanding" that you or me do when we read a wikipedia article. It's about the mechanisms in the brain that encode things.
- PaulDavisThe1st 8mo ago"Spatial frequency spectrum" typically refers to visual elements of an object, and has nothing particularly to do with its structure. Entirely smooth surfaces banded in different colors have a "spatial frequency". Extremely irregularly surfaces have no effective spatial frequency. Objects on the same scale as, say, a human head, would have to be "rubbed" at ridiculous high rates (and repeatedly) to even get into a "frequency" range that might include pressure variations that would be considered as a "wave". I think you're imagining an entirely too limited set of objects.
