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.
Tree Frogs: A steady chorus of croaking frogs in the near and distant trees. The night ambience and the broad tonal range of the pulsing sounds make this recording a good sleep aid - masking room and workplace noises and providing relief for sufferers of ringing in the ears.
