They can very loud and have impacts like shaking and rattling of houses, damage to window panes etc. Researchers have stated that the sound could be originated from fast approaching outer space object’s explosion once it enters earth’s atmosphere or due to crash of ocean waves. But none of the theories have been scientifically proved.
