Also why does it sound different when it is poured from a kettle?

The density of water changes as it reaches near boiling-point as it is in a partial transition between its liquid phase, and its gaseous phase. Thus, boiling water when poured, is 'quieter' than cold water when being poured into a container.
The taste change also relates to the fact that the gaseous phase of the water is entering your nasal cavities, and making them react, where cold water does not have the same amount of volatile components to excite the sense of smell. Remember that taste is as strongly related to smell as it is the effect on the tastebuds.

in near boiling water, some of the water has already become a gas and has escaped, that's why there are bubbles. the water then tastes different because there is a higher concentration of impurities because there is less water. it's like orange squash, if you add less water, then you get a different taste.
the sound is just some of the steam escaping, if you mean the whistling sound, than that is the steam escaping between the edge of the kettle and the water pouring out of it.

Who can actually taste water near boiling (212 degrees) ?
Who can even taste it at 1/2 that ? Not sure of your question . . .

its not the water that tastes different, its your tongue melting that makes it taste different.
