What is the loudest man made noise?

Answer 1

The loudest noise ever was the eruption of a volcanic island in the Pacific Ocean. The island of Krakatoa in Indonesia that erupted in 1883. The island blew a apart and caused a major tsunami.

Answer 2

Terrestrial Noise:

The loudest noise ever recorded was the Krakatoa eruption which was equivalent to 13,000 times that of a the little boy nuclear explosion.

Atomic/Nuclear Bomb at 210 dB (decibels) Your eardrums would pop instantly in a sudden wave of absolutely unbearable pain.

Astronomical Noise:

Although "in space no one can hear you scream," as a result of the lack of noise in vacuum (standard vibration of atmosphere type noise), the loudest noise in history (or prehistory in this case) was the big bang. Next to that is a supernova.

Answer 3

I'd imagine that the blast wave noise from an atomic weapon would be the loudest man-made noise, but I can give no figure. The largest of these was a hydrogen weapon named Tsar Bombe, and had a yield of 50 Mega tons.

Other than that, probably the Saturn V rocket - actually a set of 5 rocket engines would also be in the running, and has a more sustained noise.

The Thunderscreech airplane, XF-84H produced sonic blast waves from its supersonic prop that caused real problems, and could be heard 40km distant.

A Space Shuttle launch generates over 200 db. (more than a few atmospheres of over-pressure).

An explosion at Norfolk Naval Facility in 1943, was heard 30 km distant.

[In Port of Texas City, a1947 explosion of a shipload of NH3NO3 gave a demonstration of this powerful and cheap explosive. Made a hole in the harbour. Was heard 150 km away in Louisiana. ]
