A sound at my back, slow and rhythmic, but unintelligible.

He could hear the slow sounds of anguish and confusion.

They made a slow fizzing sound as they moved through the air.

Her black dress rose up and down with every step, making a slow thundering sound.

He could hear the sound of her breathing, slow and even.

The soft slow sound of the Hudson River all about me.

A slow grinding sound started in one corner of the large chamber.

Within was a stir, a slow sound of feet.

She heard Richard's whisper over the slow sound of the chanting.

The masseuse started a slow humming sound in her throat.
