The third explosion has been reported as the loudest sound in history. [6] [7] [8]: 602 [4]: 79 The loudness of the blast heard 160 km (100 mi) from the volcano has been calculated to have been 180 dB. [9] Each explosion was accompanied by tsunamis estimated to have been over 30 metres (98 feet) high in places.
The explosions constituted what was then the loudest human-made sound in history, and could be heard in London. The largest single charge was the Lochnagar mine south of La Boisselle with 60,000 lb (27 t) of ammonal explosive. The mine created a crater 300 ft (90 m) across and 90 ft (30 m) deep, with a rim 15 ft (5 m) high.
Such noise is known as broadband noise and extends well beyond the range of human hearing (100 kHz and higher). Jet noise is also responsible for some of the loudest sounds ever produced by mankind. Sources of jet noise
NOAA's Christopher Fox did not believe its origin was man-made, such as a submarine or bomb. While the audio profile of Bloop does resemble that of a living creature, [4] the source was a mystery both because it was different from known sounds and because it was several times louder than the loudest recorded animal, the blue whale.

In 2002, Fox was interviewed by David Wolman for an article in New Scientist, where he stated that he did not believe its origin was man-made, such as a submarine or bomb. Fox also stated that while the audio profile of Bloop does resemble that of a living creature, [ 2 ] the source was a mystery because it would be "far more powerful than the ...

A thundering sound was heard from the mountain Batuwara [now called Pulosari, an extinct volcano in Bantam, the nearest to the Sunda Strait] which was answered by a similar noise from Kapi, lying westward of the modern Bantam [ is the westernmost province in Java, so this seems to indicate that Krakatoa is meant]. A great glowing fire, which ...
Loudness, a subjective measure, is often confused with physical measures of sound strength such as sound pressure, sound pressure level (in decibels), sound intensity or sound power. Weighting filters such as A-weighting and LKFS attempt to compensate measurements to correspond to loudness as perceived by the typical human.
