Chapter 1370: 3 Party Invasion.

This sound attack produced by the sound blaster is a weakened version of the scream that dominated the battlefield when the plane was invaded by the Supreme beasts. However, each sound blaster is an Origin weapon and there are thousands of them, not just one. So they have the advantage of quantity if not quality.
