Why does white noise work? Is it because the spectral density of both the Dirac impulse and white noise are flat, and our ears don't care about phase?

- dspig 9y agoIt doesn't have to be white - pink noise works the same just sounds more muffled/bassy. It's more that there is no distinct pattern in the time domain for the ear to pick out, which would add echoes or metallic ringing. The same as a boxy room or shower cubicle will ring/resonate at certain frequencies, but a bigger more complex shaped room will have an effectively random pattern of reflections for a given source and listener position.
- regularfry 9y agoIt's simulating a randomly distributed set of acoustic reflectors. Well, ish. Makes it sound more like a room with stuff in it rather than being in a box.
