Residents search for the cause of the strange acoustic anomaly reported in Kiev

August 13, 2011 – KIEV – This was of such sound intensity that it shook windows in buildings. If you can prove and argue that this was coming from the building, please do so and we would welcome it. This was recorded on the 5th floor. Construction work is truly in nesokolkih neighboring houses, and is heard on the video but the construction work – sounds like a mosquito squeak in this terrible hum. Neither the power used nor the power of sound construction holds any comparison with what was heard. If you turn up the speakers to max, and lean against them, you’ll get the same effect people got when the sound was heard.” -       Всё не просто так
