Well, her power level fluctuates according to the writer. I remember an issue of Batgirl where she helped out Cass by LEVELLING A MOUNTAIN that was in their way.

@Anonymous: They attenuate the noise level by 30dB (i.e. the resulting sound will have an SPL of 30 dB less than it did before). It’s not “subtracting” strictly-speaking although that’s what happens to the numbers, yes (that is how logarithmic scales work).

[...] It’s no wonder her sonic scream is so powerful with a set of lungs like that. [...]

How exactly do the “30 db earplugs” work?
Are they good against noise up to 30 db, or do the subtract 30 db from the noise level…?

300 decibels is nothing on Cyborg’s (at least during the Wolfman/Perez Teen Titans in the 80s) “million decibels of white sound” that he would shoot at people. Which extrapolating the above chart would seem to be slightly louder than the Big Bang.

BATTLESHIP NEW JERSEY FIRING ALL 9 SIXTEEN INCH GUNS = 215 decibels.

What about “standing on the deck of the USS Iowa while fires a full broadside”?

So a more reasonable level of the “Canary Cry” would be around 150 decibels then, with the possibility of it going up to 200 should it need to? That would seem to fit in with what we’ve seen of Black Canary’s powers in the comics.

So the Canary Cry is more powerful than Black Bolt’s voice?

Yikes! And to think of all those wasted hours at the Duane Reade agonizing over whether to get the 27 db earplugs, or paying the extra dime for the 30 db. Earplugs for sleeping are de rigeur in NYC, what with 3 AM garbage pickups and drunks stumbling home after 4 AM last call – I know they really don’t block out that much noise, they just make me FEEL better.
