Initial data
Traveling to Alaska, tourists stumbled upon a frozen pond. Stopping by to enjoy a beautiful view that opened from the shore, a traveler thrown into the water stone.
Suddenly from the icy lake I heard strange sounds resembling birdsong. The surprise of the tourists knew no bounds. For a moment they were speechless. What caused the mysterious phenomenon remained a mystery, reports the Mirror.
Similar cases have occurred before. In 2005, the American ufologist Alan Polanski explored the abandoned South American lake, from which, according to local residents, there were strange noises. However, to establish the nature of this phenomenon, scientists have not managed.
In Russia, too, has a mystical lake, where people hear strange noises. The most famous of these is the lake in Nizhny Novgorod the Volga – Svetloyar. One day the Russian expedition managed to fix the confusing signals using hydrophones. "These sounds do not belong to living beings and are clearly man-made origin," said the researchers.
However, the study of "noisy" lakes have not been conducted. Experts say that the cause of the phenomena can be karst processes. Specialists in bioenergetics believe that in places where you hear strange sounds from under the ground to happen a powerful energy emissions that can make people hallucinate. However, the answer to the question as "hallucinations" cannot record on tape and digital media, yet.

Investigation
The reasons for this phenomenon is quite known, it is familiar to many villagers.
In any case, I looked for other audio and video recordings of this phenomenon. The first link showed a video from "Vkontakte" authored by Alexander Poteryakhin:
Wonderful sound produced when you toss a stone at first-ice.
I also found a very detailed hypothesis that explains this phenomenon, S. Varlamov, mioo, sunts Moscow state University, Moscow. I see no reason to bring it here in full, who cares - pass the link. Will give a simplified version.
Thin ice on the water surface plays the role of the membrane. Throwing on a stone, we generate fluctuations of water ice in a wide range of frequencies. Vibrations at the resonant frequency are damped very slowly, others very quickly. After some time after a throw stone water in the ice varies with a certain frequency - a natural frequency, which depends in particular on the depth. The water pressure on the ice from below, and he makes sounds, playing the role of membrane dynamics. In addition, the ice layer propagates the perturbation from throwing a stone at some distance around the epicenter. Thus, the ice varies in different parts of the surface, with different frequencies (for different depths) and the amplitude (which decreases as the distance from the place you got the stone). We receive a large set of sources of sound waves. The sound at the point of reception (the place where the observer is) is determined by the sum of these fluctuations, and generally can have a modulation frequency, and level (the beats). This is what we hear in both videos.
