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.
Mountain Stream: A narrow, fast-flowing mountain stream with a fallen log forming a natural waterfall, flowing into pools and eddies. Rushing water, a few frogs croaking in the background, and occasionally a songbird in the distance. A wonderful relaxation recording and excellent for masking ringing in the ears.
