Do humans make bodily or vocal noises above or below the human hearing (20Hz to 20,000Hz) threshold?

Anything that causes a vibration causes a sound, because that's what sound is. While it may not be audible, pretty much any movement your body makes technically makes a sound.

Waving your hand frantically may cause vibration of a few Hertz, for example, even though it's probably very quiet too. Of course, that's just an example you could easily mimic on purpose.

Short answer is yes.
