Sound Noise and Music Curiosities
Which of these surprising facts about human perception and sound accurately describes the phenomenon known as the Shepard tone?
Correct
This auditory trick is like an endless staircase for your ears. By layering tones and slowly shifting their volumes, the brain gets tricked into thinking the pitch is moving infinitely in one direction, even though it is just cycling through octaves. Losing your balance because of a frequency sounds like a fun science fiction plot, but that is not what this does. Outer space is indeed quiet, but it is not a musical tone. Finally, while some sounds are palindromic, they are just normal audio, not the clever, brain-melting illusion of a never-ending rise or fall.
