The shrill sound of a police whistle came to his ears.

The smaller animals, in turn, can produce and hear shriller sounds.

And then, among the chatter, he heard a shrill little sound that was quite new to him.

The minutes seemed like hours, but then there came the shrill sound of the train whistle.

From a distance came the shrill sound of a police whistle.

It was an awful, shrill sound, like someone looking at Death himself.

A moment later, the shrill sound of an alarm came from the hut.

Even as his head jerked, she heard the shrill sound herself.

From the hall outside the apartment came a shrill sound.

The shrill sound sliced through the singing of the wind and then it was gone.
