This is no fake! If you visit the Whispering Wall at Barossa Dam Reservoir you will be able to hear the person on the other end as if they were standing right next to you without any microphones or anything else!
Weird, no? If you do not believe me, watch the following videos of this strange and eerie phenomenon!
Well you are probably not totally convinced. Try this next video:
The Whispering Wall is the first reservoir to have ever been built in South Australia between 1899 and 1903. It is 140m long, arch shaped, letting the noise travel without obstacles (parabola effect). In top of being an engineering highlight, now it is an incredible acoustic attraction.
I would like to try this place, what about you? Do you know the ringing rocks Park?
