Translation: 
Then from within the pillar came a fearful sound, which appeared to crack the covering of the universe. O my dear Yudhiṣṭhira, this sound reached even the abodes of the demigods like Lord Brahmā, and when the demigods heard it, they thought, “Oh, now our planets are being destroyed!”
Purport: 

As we sometimes become very much afraid at the sound of a thunderbolt, perhaps thinking that our houses will be destroyed, the great demigods like Lord Brahmā feared the thundering sound that came from the pillar in front of Hiraṇyakaśipu.
