Hello how may I help you? Hi, I was wondering if you could answer something for me. yes i can help What is the loudest recorded sound EVER? the loudest sound ever recorded was from the Krakatoa volcano eruption How loud was it? it was about 26 megabels That's crazy. Would that hurt human ears? it would shatter your ear drums if you were nearby Did anyone go deaf from hearing it?!? yes there were a few but no one died luckily
