Sough

Your voice is a voice from the days that are gone, and the old tongue comes back to me, with the sound of the piper on the hill and the harper in the hall, with the sough of the summer wind in the fir trees, and the lash of the waves on the rocks.

I lay awake for a while that evening, listening to the soughing of the wind high in the pines, realizing sadly that we must now return to civilization.

[...] Arthur; a fearful night it was: there was a sough in the air, a sound drawing nigh like that of a host marching:- — but you're looking pale and forwrought, man; is any thing ailing ye?

The whispering leaves or solemn sough of the forest.

Syenite hears the distant sough of waves rolling against rocks, somewhere below the slope on which they lie.
