For a few moments it might be that his companion hadn't heard.

He and his companions heard a roar from the road that they had left.

Her companion would hear the 'click' as the tape stopped.

In the following silence, the three companions heard a persistent tapping on the front door.

His companions had heard the shot, and ran up to see what had happened.

But if her companion had heard her he gave no sign.

The companions heard him and cast quick glances at each other.

Her companion must have heard the impact, because he stopped and looked back over his shoulder.

He turned toward the inner door, thinking that his companion would hear his words.

As if to emphasize his words, the companions heard sounds above them.
