Cicada Chorus 2. Cicada Chorus 2: A few songbirds in the background and an occasional woodpecker hammering add to this mid-to-high range tonal spectrum. Like grasshoppers and katydids, cicadas use a constant stream of chirping sounds that make this recording a favorite masking choice for those with ringing in the ears. A great soothing and relaxing sleep aid. Put on your favorite set of headphones or earbuds, sit back and relax in your recliner or sofa, and let time pass in your state of total relaxation.
