From My Other Blog - Tumblr Posts

Okay so I just found out that

Most people can't voluntarily flex their tensor tympani muscle

I can.

According to Wikipedia:

Some individuals can voluntarily produce this rumbling sound by contracting the muscle. The rumbling sound can also be heard when the neck or jaw muscles are highly tensed as when yawning deeply. This phenomenon has been known since (at least) 1884.[5] According to the National Institute of Health, this is an extremely rare condition.[6]

If you want to know what it sounds like and you can't voluntarily do it, tense your fist really hard and hold it up to your ear. I recommend pressing your thumb muscle to your ear while you make a tight fist. It's less loud but the same frequency

Ima be honest

Idk how adoptables work
