Cicada Chorus 1 Nature Sounds. Cicada Chorus 1: A chorus of high-pitched cicadas rising and falling in the foreground. The sounds can be shrill so keep the playback volume low and adjust carefully. This same shrillness or emphasis on high frequencies also makes this recording excellent masking effects for locations with fans, machinery, or ringing in the ears.
Forest and Water: Bubbling, gurgling, running water, songbird sounds drifting in the foreground and background. This soundscape presents a feeling of depth, peacefulness. The sound masking attributes are good since a wide range of pitches are heard.
