TIL that some people can voluntarily control the tensor tympani, a muscle within the ear. Contracting these muscles produces vibration and sound. The sound is usually described as a rumbling sound.

This drove me crazy for a while, because I can do it- but I didn’t know what it was and I couldn’t figure out how to describe the rumbling sound in my ears. It usually happens when I shut my eyes super tight. Glad to see that I’m not alone, and that there’s a good explanation of what it is!

Ooh me can do dis! I thought it was normal
