Hello how may I help you? Give me the worlds record for biggest sound recorded. Pulling up the information now. Thanks. The biggest sound recorder in the world is called the huuuuuuuuuuuge recorder. How loud was it? It's so loud that it can kill you. I need the loudest sound that was ever recorded. The loudest sound ever recorded was when the krakatoa volcano exploded. Thanks, that was all I needed to know. Glad to be of service.
