Somebody answered him but the sound of the rain intruded and she could not recognize the speaker.

Not even the sound of the river intruded on the hot silence.

The light sound of running feet intruded on his reverie.

The sound of distant fireworks intruded on his consciousness again.

Before he knew it, a sharp sound intruded at the edge of his mind.

Then the sound of a small animal intruded on the quiet.

Then the sound of the door chime intruded on the comforting silence.

Be sure that the sound won't intrude on neighbors' privacy.

The sound of a car approaching the house intruded.

She had just started to cry when a distant sound intruded on her dream.
