Does anyone in visual perception know why you can hear this gif?pic.twitter.com/mcT22Lzfkp

Do you know what the frequency of the camera shake is? 20-40 Hz ish? Feels like it's in the range of tactile flutter-vibration.

More generally, I'd expect your brain to be more aggressive at filling in priors near the high/low ends of the auditory spectrum (that is, around 20 Hz).

Interesting idea. Do you have functional (e.g. why it would be advantageous) or mechanistic (e.g. a side effect of brain/eye/ear structure) reason for that prediction?

Well, presumably we don't have a hard lower cutoff to what freq. sounds we can hear. So in this 10-50 Hz range, you're getting some info from the auditory system, but it's weak and hard to discriminate. That weak regime is where I'd expect multi-sensory integration to kick in.

Oh, more hand-wavey evidence: this is in the range of modulation frequencies (1-150 Hz), which are likely decoded by central mechanisms, rather than the cochlea. That probably makes their perception more apt to central (multi-sensory) modulation than higher frequencies would be.

This is almost surely the right explanation.
