Comment on My earphones' cable has been oozing sticky goo for over a yer now
KingOfSuede@lemmy.world 1 day agoDoesn’t matter if the pinna is bypassed or not. 3d audio (soundstage) requires both ears to receive signal from the same point source. The time delay between the two ears receiving the signal is the crux of the entire premise. Headphones inherently defeat that entirely by having the entire ear subjected to one side of the audio.
Ergo, headphones do not provide any 3d audio or soundstage.

That’s not entirely true anymore. Sound engineers did lots of experiments with microphones placed in the ears of plastic heads, and as a result, we know the modifications that need to be made to a sound to make it seem like it’s coming from so specific point when played through headphones. It works with both over-ear and in-ear ones and works well (despite what the other poster said) as pinna squiggles are accounted for and it turns out that humans don’t need their own personal pinna shape for it to work.
You can find impressive demos by searching for binaural sound, both from microphones in a plastic head or with simulated HRTF.
