Hello how may I help you? Hello, can you please tell me some information on world records? I certainly can! What information do you need to know about a world record? What was loudest recorded sound ever? The loudest recorded sound ever was the eruption of Krakatoa in 1883 How loud was it? More than 170 decibels Did the eruption hurt anyone? Yes. It is estimated that 36,000 perished as a result of the initial blasts and resulting fires. That's unfortunate. Thank you so much. No problem. Have a great day.
