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.
Ocean Waves: The steady pulse of light surf as waves roll onto a sandy beach. The occasional sea gull squawks and adds to the effect. A natural, soothing soundscape, this environment recording makes a wonderful sleep aid and is especially useful as a masking sound for ringing in the ears.
