Zoom unleashes an army of Earth-2 meta-humans, the leader of which is Black Canary's doppelganger, Black Siren; Joe worries when Wally goes out to help The Flash.
I admire what you're trying to do, but the best way to help is to just... leave this to the police.
Wally West: Like you did.
The Flash: I do have powers, Wally. It is a little different. This isn't your fight. It's mine.
Wally West: No, it's all of ours. This is my city, too, now, ...
After Black Canary unleashed a sonic scream to incapacitate The Flash, the scene switches from an on-the-streets view of the confrontation back to STAR Labs, where on the computer screen data about her attack is recorded. At the top of the screen, "250 DB" reads, indicating that the loudness of her scream was 250 decibels; however, the loudest theoretical sound that could be observed or recorded is 194 decibels. For practical measurements, past around 170 the scale for loudness falls apart; measurements this high only reflect energy, not loudness as the vibrations become more of a shock wave rather than an observable sound. At 250 decibels, the amount of energy for this sound is approximately equivalent to the explosive power of the atomic bomb dropped on Hiroshima.
