The only sound from the listening host was their soft breathing.

For a while, she heard nothing except the soft breathing.

There was no sound in the crowded room except for soft breathing.

I could hear his soft breathing, but that was all.

From the far side of the room came the soft and steady breathing, a woman in sleep.

Only his soft breathing let me know he was still there.

Soon the sound of their soft breathing could be heard.

Within a few moments his soft breathing was regular and deep again.

From the far side of the room he could hear her soft, regular breathing and smiled.

I turned my head to the side, where his soft breathing came from the darkened floor.
