If Blackbolt screamed at a planet, it would be destroyed. He would never do that though.
I will show some examples. In this scan he defeats Apocalypse with merely a whisper in HoM. Notice the area of destruction:

It is basically a cone effect. The area behind him is still intact. The actual effect that's occurring is that the electrons in between him, and in a cone shape radiating outward, become excited. The sound is merely a side effect, this is why BB's scream is different than any other sound based hero villain.
His actual power is manipulating electrons. He can use it for other effects, for example creating a containment field:

When he channels it through his vocal cords, it is merely a focus for his power in the form of a scream in it's most destructive form. For example he can use it for other things without needing to speak:

His full blown scream is many times stronger than a full nuclear payload. A mere whisper can destroy a mountain range. When he uses his voice, it basically causes the electrons in the matter in a cone shape in front of him to vibrate such that it causes damage; with a full blown scream it literally rips the electrons from the outer shells of the atoms and molecules.
In the past when Hulk fought BB Hulk always lost. That just shows how much more powerful the current incarnation of Hulk is. Hulk has withstood planet shattering blows from numerous opponents; his body is far more durable than an entire planet. Gladiator got whooped, and he can easily move planets and is extremely fast as well (can easily keep up with ships in hyperspace). The first whisper BB used at Hulk was to subdue and not kill him. You can clearly see skin being ripped away from the Hulk's face and body from the first whisper and Hulk getting knocked back.
Had the fight initiated with a scream WWH would have been utterly destroyed. Since the Hulk survived the whisper though and it reminded him of the explosion which killed his wife, his anger channeled into his strength and durability, making him exponentially more strong than he was when the fight started. In addition his regenerative powers increased by the same amount, he healed from having skin ripped off his face to full health in less than a second. This angered him even more, giving him the chance to leap in and attack BB for the win.
