When you yawn, your mouth makes a sound to releive the joy of yawning.
I'm pretty sure it came from the sound of when one "yawns."
No. They yawn for the same reasons we do.
they yawn because when you yawn it passes on to other people . so you yawn then someone's right next to you then i think they inhale then they start to yawn ?
yes they yawn quietly
how do you know you yawn if you are sleeping?
The typical written expression for a yawn sound is "ho hum."

The pressure change in your head affects your hearing.
The word "yawn" has the same vowel sound as "lawn."
I'm pretty sure it came from the sound of when one "yawns."
No but they make a noise that sounds like barking
Yes. It is a vowel with the sound of a long E.The only time a Y is a consonant is when it makes the "yuh" sound as in yawn and yellow.
No. They yawn for the same reasons we do.
Guinea pigs do yawn in fact....Usually they yawn because they are surrendering a fight involving a male guinea pig. But it does not mean they are sleepy. Before males start to fight they try to intimidate each other by purring ( a deep sound with trills , Not like a cat) Then the loser of the fight yawns which means they are conceding. Hope I helped :)
This is a funny question that I just had to take a stab at! :) I do not think it is actually the yawn that makes the noise, but most people stretch when they yawn. This is known as pandiculation. This is just a guess but when you stretch it tightens the vocal chords similar to the strings on a guitar. The yawn itself takes in air quickly which strum the chords (hope you can follow a metaphor, cause I can't think of how else to explain it) and produce the noise you hear when you yawn. This is why breathing alone does not cause the noise because the vocal chords are not tightened. Like if you were to try and play a guitar with very loose strings, it would make no sound. This is just a theory, but it is the best explanation that I have. :)
