Since very early morning, I had heard the constant boom of church bells.

But we don't hear the sonic boom or anything like that.

Shimon took up position near the window, waiting to hear the boom.

Behind us we could hear the boom of guns from the ships.

Tom had not heard the boom of the seaplane coming down on the water.

Out in the rain he could hear the boom of bombs.

Even with her head in the water, she heard the deep boom of the surf against the cliffs.

I heard the most tremendous boom, and some of the marble fell off.

I heard the boom of the cannon as the race suddenly began.

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