  That’s boring. Two ears only allow you to put the sound somewhere on a plane (the vertical one that cuts your body in half lengthwise). How do you know the ‘height’ of the sound on that plane? By utilizing the different distortions the sound goes through while being funneled through your auricle.

    Also that everyones brain has tuned this perception based on their own ear shape, and if you add prosthetic ridges to someones ear they become very bad at determining the noise source direction in blindfold tests.

    Also, moving your ears and your head.

  My hearing is pretty severely damaged in my left ear, and for several months I thought everything was to my right. but I’ve my ability to locate sounds has come back. My hearings not any better, my brain just figured out that my left ears fucked and compensated.

  I think the “more to it” might be significantly crazier than the timing thing.

  Or ears have unique complex shapes that attenuate certain frequencies and bounce sound around in complex ways depending on the direction they ate coming from. And our brains instantly process all that stuff too. It’s why our sense of hearing isn’t just on a flat plane around our head.

    And we can also slightly move our ears a tiny amount, but I’m sure even that does increase accuracy.

  Put on some halfway decent headphones and try out the virtual barbershop.

  You can also detect is the source up or down thanks to ear shape which delays sound for couple of ms.

  Beyond that there’s been a considerable amount of research about our ability to estimate room size/material/shape while blindfolded just based on the reverberation of sounds in the space.

  Oversimplified conclusion, untrained humans are really good at it.

    We can also hear the difference between hot and cold water from the sound it makes while being poured into a cup
