eli5: what is the purpose of the vibrating muscles around our head?

313 viewsBiologyOther

When you use them, you can hear and feel a “rumbling” noise that sounds like it is coming from inside your brain.

What is the actual purpose of these muscles and why do we have them?

That is the tensor tympani. Not everybody can voluntarily contact it which might be why the first responder doesn’t know what you’re talking about. But I am fellow ear rumbler

Your ear has a drum with a round surface like the instrument drum. When you hit a drum (instrument) it’s very loud. If you put one hand on the drum and then hit the drum, the sound is quieter. The tensor tympani dampens loud sound going through your ear drum
