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.
Wind and Ocean Surf: Waves roll onto the shore in a cascading surf. Steady and pulsating, growing louder as they approach the shore as they break apart, then disappear. Sea gulls squawk as the wind ebbs and flows. The combination of wind and waves creates a tonal sweep of audible frequencies, making this recording a good sleep aid and masking sound for unwanted noise in the home or workplace.
