My two daughters can generate a lot of noise. But nothing (so far) beats the sound of an exploding volcano. Last night I watched a documentary on the Krakatoa eruption in 1883. It generated the loudest noise (up to 180 dBSPL) ever recorded.

From Wikipedia:

Krakatoa: The 1883 eruption ejected more than 25 cubic kilometres of rock, ash, and pumice, and generated the loudest sound ever historically reported — the cataclysmic explosion was distinctly heard as far away as Perth in Australia (approx. 1930 miles or 3100 km), and the island of Rodrigues near Mauritius (approx. 3000 miles or 4800 km). Atmospheric shock waves reverberated around the world seven times and were detectable for five days.

Just so you know…
