Sound cannot travel in a vacuum. It has to have a media (air, a solid) to travel through. Hence, an exploding star wouldn't make any sound at all, depsite that of which is traveling through its own matter but does not extend into the vacuum of space. Sound if a wave caused by a vibration (sometimes by percusive force eg. explosion). Jupiter has an atosphere, think how loud the sound would have been during the shoemaker-levy comet impact. We do not know even a tiny fraction of what exists in the universe . Being that civilians will most likely never make it off this planet the loudest sound that would could personally experience would be a large comet or asteriod impact. and we would have very long to experience it

You complicate things a lot by specifying the whole universe. This makes it necessary to define what 'sound' is. There are colossal energy releases that take place all over the universe - Gamma Ray Bursts as mentioned previously, supernovae, black hole collisions, the Big bang itself - but none of these would be audible, even close by, if there's no air to carry the sound.
Other factors: sound and loudness are things we perceive with ears, and our bodies would be utterly fried by radiation, torn asunder by gravity gradients etc. if we were anywhere near these cosmic bangs.
The loudness of sounds is a function of the degree of displacement of our eardrums, the tiny ossicle bones that conduct that conduct that to our inner ears, and the degree of shaking that the nerve endings in our cochleas finally receive at the end of this chain. After that, the 'sound' is an electrical nerve signal that heads to our brains to be interpreted.
Decibel meters and other loudness-measuring devices try to duplicate the ear using precision microphones. Could we make such a device to measure a GRB or supernova? It's possible in theory, though it would have to be very strong indeed not to be blown apart by the shock-wave.
Do we treat the mechanical shockwave as the 'sound' of the blast, or do we take all the energy into account? The gamma ray jet could blow up stars at huge distances if it hit them. That would make a sizable bang.
And where should our sound meter be placed to make the measurement? Radiated sound energy decreases by the square of the distance from the source. But most cosmic bangs don't have point sources - the energy may be emitted from ultra-hot plasma light-years wide.
The only measurement that makes much sense is to consider the entire energy release as if it came from a point source, and that's a problem, too. Most GRBs emit their energy in a narrow jet. And GRBs, as the man pointed out, are the most energetic bangs in the universe. Except for the big bang itself, of course - but that's not something you can stand outside and measure: you have to be in it because it *is* the universe.
So the answer is - it depends.

The loudest noise generated by humans is probably a thermonuclear bomb like the one that were detonated at the bikini islands. Before being destroyed, microphones recorded a decibel level of approximately 248 decibels . That sound is loud enough to punch holes in concrete.
Of natural events, the volcanic eruption at Krakatoa surely ranks up there on anyone's scale. The sound was attention getting as far as the island of Rodrigues near Mauritius which is approximately 3000 miles away.

Well it wouldnt be anything in space as there is no sound there, so even the explosion of a star would seem like the loudest sound but it wouldnt actually make any? As for in the universe we cant really know because it could be inifinite with other beings (you never know!) who have louder sounds that us humans. I guess we can only go by whats the loudest sound on earth!.....so....huge nuclear warhead explosion perhaps?

Hmmm, I think there would be louder sounds out there.
At first thought, I imagined that those you listed could easily be outdone by for instance massive black holes colliding, but the science is deeper than that, i.e; sound travelling in a vacuum etc.
I know the Harrier jet was one of the loudest aircraft on this planet!

Possibly the loudest sound in the universe was the1883 volcanic eruption on the island of Java in Indonesia.
"...the 1883 eruption of Krakatoa ... obliterated most of the volcanic island and created the loudest sound in recorded human history..."

Hillary, Pelosi and Feinstein singing "The Gang's All Here" No wait, that's not the loudest, just the most annoying.

Silence.
Particularly when it's late at night, maybe you can't sleep, and you suddenly realise that all day there's been constant sound and now there's none... except for the slight frequency inside your own ears... and now that you think about it, that's loud... and it won't go away.

well the loudest sound in the universe is that of heart beats when a person is either afraid or in love.
