They themselves made the only sound to be heard in this dead city.
For a long moment, the only sound was the wind.
The only sound was from a security guard's television set.
That will be the only sound the film students make.
The only sound in the room came from the bed.
His voice was the only sound in the room for long minutes.
Then the wind was the only sound in the night.
For a long time they were the only sounds in the world.
The only sound in the room, or so it seemed.
In fact, that was the only sound coming from it.
