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.
Pink Noise: A broad range of noise sounds that can be mistaken for the rushing water sounds of a waterfall or very fast flowing stream. Steady, constant sounds make this an excellent sound masking choice for those suffering from ringing in the ears.
