From Destinypedia, the Destiny wiki
The Deafening Blasts are Ultra Knights that serves as the bosses of the fourth and sixth levels of the Escalation Protocol World Event. They are some of the most powerful Knights ever encountered by Guardians and are deployed to sabotage Rasputin with their assault force. There will always be 2 paired with each other as well as a Renewal Wizard providing health if any was lost.
These Knights will always come in a pair, as well as being followed by a Renewal Wizard, which can heal any damage done to the Knight. Like the other Escalation Protocol bosses, they will have an impressive health pool and a high damage weapon, and a vast horde of Hive back-up. To neutralize the duo, it is recommended to eliminate the Renewal Wizard, so that she won't heal any of the Knights. Then, the group is advised to lay into the Knights with as much as they got once the Wizard is killed. Once both are dead, the next round begins (either Round 5 or the Final Round).
