As they walked, the air began to rumble with distant sonic booms.
A distant boom of sound struck through me, and the floor trembled.
Surf sounded with a distant boom and the wind moaned.
There was nothing but the distant boom of surf.
A distant boom echoed through the floor beneath their feet.
They heard the distant boom of a heavy port being sealed.
A distant boom as the external door bursts open.
A shout rose up above the distant boom of surf.
There was a distant boom of an avalanche, high among the peaks.
Seconds later came a distant boom, then several others.
