I asked this question to my sister she said i dont hear any noise. Am i the only one to hear it?
In: Biology
It’s probably your *tensor tympani*, a tiny muscle in the middle ear that helps muffle loud sounds to prevent hearing damage.
>Contracting muscles produce vibration and sound. […] The sound can be heard by pressing a highly tensed muscle against the ear, again a firm fist is a good example. The sound is usually described as a rumbling sound.
>Some individuals can voluntarily produce this rumbling sound by contracting the tensor tympani muscle of the middle ear. 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.
