One of my favorite sounds in the world, the sough of rain on a bedroom roof while curled up reading a good book :)

sough \SAU; SUHF\, intransitive verb:

1. To make a soft, low sighing or rustling sound, as the wind.
2. A soft, low rustling or sighing sound.

At a recent visit to Marsha's grave in Rathdrum, as the wind soughed through the towering pines nearby, Marsha's brother Pat left a silk bluebird by her headstone to honor her love of the outdoors.

In the dark of winter, tin roofs sough with rain.
-- Les A. Murray, "Driving Through Sawmill Towns"

This voice she hears in the fields, in the sough of the wind among the trees, when measured and distant sounds fall upon her ears.
