What ever you read on that site was a lie, I got this information off another black bolt site.
The most prominent manifestation of his power is the destructive potential of his voice. If Black Bolt uses his voice at a shout, he has the damage capacity of a 10 megaton nuclear warhead. This effect is not just a shockwave, but a wave of transformative energy, destroying everything that it touches. Because of the extreme danger posed by his voice, Black Bolt has learned to practice rigorous mental training that prevents him from uttering a sound, even in his sleep.
It clearly states that his scream destroys everything that it touches.
