the soughing of the wind in the canopy of branches above their heads
The silence was broken only by the soughing of the wind through the City's concrete canyons.
Yet no sound was heard, but the soughing of the winds through the budding trees, and the murmur of the brook.
She sat still listening, but there was no sound except the soughing of the wind among the naked apple trees.
The smell of pine was thick and fragrant; the sound of wind was sweet and soughing.
You can hear the wind soughing through them and the branches creaking a little and rubbing, and a still kind of light all around.
