It's weird, I experience a thudding sound, but I know it's not coming from my ears. — Marchesk

Do we experience any sounds coming from our ears? Our ears are a stereo system that help place sounds appropriately in space. So we hear sounds coming from the place they are likely being made.

With a gif, we are imagining the thudding sound. And the kinesthetic vibration in this case. So the stereo locatiing information is missing. But if you start focusing on the question of "where is the sound coming from", doesn't it start to come from the gif?

Maybe turn your head and look at the gif out of the corner of your eye. Doesn't it start to seem located?

I perceive sound external to my ears, and that sound can hurt my ears if it's loud or shrill enough. This is different. It's like an internal auditory hallucination.

I don't experience a sound. I would say that you are gifted with synaesthesia, except that the article says that 70% of people experience the sound. So perhaps it is rather that I am missing a common mental faculty (it won't be the only one I'm missing! :D )

Yes but we still know there isn't a sound though without having to be told. At least I think we do. I know that sound can't play on this board so perhaps I am fitting that into my interpretation.

I think more than hearing the sound, the phenomena is more of an expectation to hear it or more a feeling that we've heard it. The large objects jumping and landing and the consequent shock-waves that would follow are some way or another conveyed in the illusion, and so the noise is perhaps tailored in the brains attempt at filling in the gaps.

I suppose auditory illusion is the better categorization.
