Talk:Sonic Scream/@comment-5177743-20121013192223

The larynx, or voice box, is the set of vocal cords in the throat and sound-making instrument in the human body. When you speak, your larynx vibrates, produces and releases sound waves from your mouth. Sonic Scream would probably require a LOT of sound energy to be produced from your larynx. So unless you're Superman or any other Kryptonian in the history of DC, don't attempt to scream too much. You'll lose your voice!
