ELI5: Why does the wind make such a distinct sound against a microphone, but we don't hear that sound against our ears at all?

We all know the crunchy, flappy sound of wind getting picked up on a microphone. I'm not asking why that happens, I understand that.

I'm asking why that sound is so different than what our ears pick up. We don't hear anything close to that sound. It's not like the wind-in-a-microphone sound is just quieter in our ears — it doesn't exist at all!

Why does that happen?

Thanks!

There’s a lot more mechanically going on within our ears than with microphones. For starters, ears are shaped very differently than a microphone, out of different materials. The curls of the outer ear, shape of the ear canal and cilia (little hairs) affect how sound vibrations hit our eardrums. Plus, our brains filter sound, so what we hear is not necessarily what we perceive.
