Cacophony of sound

Ringing in the crowd!

Where is it stored?

You can never ignore

This clashing of noises,

Ripping through your head

It goes unsaid-

Or does it?

Haha, laughter of a puppet

Sources say that's not the source

The mouth? The throat?

You can't touch it, or it gets quite hoarse

Can you answer this riddle of mine?
