Blackbolts bio: http://marvel.com/universe/Black_Bolt
"This "quasi-sonic" scream is powered by electron energy that he draws in from the environment. At maximum the force is equal to that caused by the detonation of a nuclear weapon." [/B]

Again from Blackbolts Marvel profile.
"As an infant, he demonstrated certain energy-manipulative powers that he couldn't control, particularly that of producing quasi-sonic energy of great destructive potential. To protect the other Inhumans, he was placed inside a sound-proofed chamber"
Seems to prove that canceling the sound, cancels the attack.
In JLA Classified 15, New Maps of Hell.
Superman shows us, with his ability to speak in any frequency. He can also cancel any frequency by using his vocal chords to emit sound-cancelling white noise.
Thus, shows that Superman can either take the attack directly, without missing a beat, as shown in the other post I'm quoting[since he took a similar attack that was apperently 10 times stronger than Black Bolts max], or cancelling it completely.
