The bomb exploded with a dull boom and men screamed.

Behind him he heard a dull boom as a gas tank exploded.

Outside there was a dull boom, followed at once by a low, steady roar.

Almost as he said the words there came a dull boom and a cloud of black smoke.

He heard a dull boom as the guy's head hit the metal and then he was gone.

There was a dull boom off to the right; the firing of a single cannon.

Suddenly a dull boom was heard from somewhere, the exact direction could not be located.

He brought his hands together with a dull boom, rubbed them briskly.

The dull boom of an explosion echoed through the night.

For as they reached their stations he heard the first dull boom.
