Nobody knows for sure, I am not an expert on this subject but I have observed this strange feeling. When I play my drum set with earplugs, then yawn, it sounds like the sound waves from the drums completely bypass the plugs and go straight to my eardrum. as I said before, knowbody knows for sure why we yawn. There are several theories out there, like: your body does it to take in a greater amount of oxygen when carbon dioxide level is high, but this theory has been disproven multiple times like the others. A couple things to keep in mind though: it is common for an animal to yawn before attacking another animal, and also, poeple yawn contagously.
yes they yawn quietly
Yes, yawn is an onomatopoeia.

No whales do not yawn.
Insects do not yawn. People necessarily do not yawn only when they are tired. Most people, after reading this, will yawn.
A yawn is normally a response to a change in activity, although if you did not get enough sleep, you could become tired and yawn.
