The sweet sound penetrated all the way through Jack's soul.

The sound of the sea once more penetrated the café.

The sounds penetrated my consciousness as if from a distance.

Not even the sounds of the city above could penetrate this darkness.

The sound and flash penetrated the walls as though they were paper.

No sound penetrated through the doors or walls, nothing came up from the street and I didn't hear anything ring.

Some part of me was listening, though I tried not to let the sound penetrate.

Soon, even the sound of the police and fire sirens did not penetrate his deep, rewarding sleep.

No sound penetrated from the night out of which he had come.

They stood together in the silence, not a sound from outside penetrated the room.
