What's the breathing sound a boxer makes?

[Ghost]

What is the "shhh" sound a boxer make while striking. I understand that it's him exhaling on a punch, but why does he make it audible? I heard it's for beginners to work on their breathing, and ditch the habit of holding your breath, but then I don't understand why pro boxers still do it.

I think Karate fighters say kiai too, don't they?

I'm just wondering why they make their breathing audible? Does this not use more energy then necessary. They could simply could be exhaling in silence.

I'm curious of the actually benefits of exhaling on a strike. I heard it makes you actually hit harder. Is this a myth or true?

it makes sound because your jaw is shut, at least it should be.
try gritting your teeth and pushing air out fast. makes a sound do it whie punching and you have the sound boxers make
youdont want your jaw open,will cause broken jaw toungue bitten off smahed teeth etc
