_ * In an episode of "UFO" in "Bells Svetoyara" We have already talked about the St. Petersburg enthusiast, explore the lakes of Russia voices, engineer Igor Fomin. However, the history of this phenomenon has been around for centuries, while they themselves are sounding the lake on all continents. * _
In Europe the most famous "talking" lake — Ladoga. Most fishermen who had gone on shore to 2-3 kilometers hear a mysterious rumble, rumbling like a distant echo of a Thunderstorm. When the sky is covered with clouds, these mysterious sounds (brontidy) often come across new entrants to the lake — as "vodnomotorniki" and sailors, immediately guide their ships to shore.
By the way, in various literary sources can be found distorted versions of the term, but it goes directly to the Italian word "brontidi", meaning the sounds that have been observed in some coastal areas of the Mediterranean.
It is much rarer in the Poconos has a different view brontid — long a sound similar to the sound of a broken bass string. Even more rarely can hear two or three of these sound a row. And some water tourists, encamped for the night in many archipelago north-western part of Lake Ladoga, suddenly wake up from the sound of wheels rapidly approaching train, although no train nearby, of course not.
With all the extensive statistics of observations of this phenomenon over the past two centuries, it has been found acceptable explanation, and those who speak out, sometimes just naive. In geophysics, there is a whole branch of science, called acoustic atmosphere. There are ocean acoustics, but, alas, no acoustic lakes.
Only once, in school, I read the story of the Armenian writer, it seems, "On Lake Sevan", describing how students and the teacher studied the mysterious sounds of alpine lake and the locals attributed the roar of the underwater deity.
The guys found a hole into which periodically rushed lake water, uttering at the same frightening sounds. It is practically all you could read about the study of "votes" lakes.
As for the Ladoga brontid, the reader will have to be content with a very brief statement of what might they relate to the feature of underwater currents and complex topography of the lake bottom. Not a lot? But the experts have to say something!
