The gravitational contraction energy squeezes the atoms together tightly, which then fuse. However, if this were only the case, the hydrogen would immediately collapse into a black hole. The fusing of the hydrogen into helium releases negative pressure, which keeps it from contracting. Each fusion releases about 2-something MeV, which is not that efficient, if you consider fusion reactors and the human body. Our fusion (and fission) reactors release much more energy per cm^3, but considering the mass and area of the sun, it's a whole lotta energy.
The energy is mostly homogenous on all wavelengths too.
Nuclear rays (alpha, beta, gamma) are not as common, due to the fact that fission takes place, not fusion. Fusion is more efficient than fission.
Energy is energy. Period.
The different wavelengths of energy dictate what we call "types" (ie radio, infrared, light, ultraviolet, etc.)
So, yeah...
Add:
Also, neutrinos are produced in the reactions. Neutrinos travel close to the speed of light, and about 50 trillion are passing through your body right now.
Add2: Also, "sound" does not exist. Sound can only pass through a medium like air. We can't hear the Sun.
Add3: And no, the energy is not created by the destruction of matter. The helium atom is about the same in mass. Neutrons are actually slightly heavier than protons.
The energy is created by the destruction of the strong nuclear force (or the weak one, I forgot) which holds the atom together.

The energy released in the sun is from the fusion of two hydrogen nuclei into a helium atom. The mass of the resulting helium is less than the mass of the two hydrogen atoms which formed it. The mass defect is converted to the energy you are asking about.

Because of the huge gravitational field of the huge mass that is the sun, 2 hydrogen atoms are compressed together until they fuse (hence, "fusion" energy) into 1 helium atom. This is where Einstein's famous Energy (E) = the Mass (mass) times the speed of light in centimeters, squared (C). The hydrogen atom is very small, but that "C" is huge. Factor in zillions of fusing hydrogen atoms over a ten billion year life span and one has a prodigious amount of energy thrown off--enough to kill if we were any closer.

Good night. I'm brazilian e don't write very well english. The sun's energy it's convert in radiating energy in the form of electromagnetic waves of different wave lengths.
