Phenotype: Can you make a rumbling noise occur inside your ears voluntarily? (Voluntary tensor tympani control)

You can cause a low rumble to be heard (like thunder) if you can control your tensor tympani muscle inside your ear.

The sound created is similar to clenching your fist and putting it against your ear.
