What I hear when pouring water from one cup into another (trying to maintain the same flow rate and height) is a more distinct sense of pitch and more loudness in the burbling of the cold water compared to the hot. Note that this effect is most detectable when the hot water is in fact right at the boiling point.
The main mechanical difference between the two is the water's vapor pressure, and the hotter water has a higher vapor pressure, reducing surface tension and making cavitation more possible. The dissipative effect of cavitation may account for the apparent reduction in sound intensity and ringing.

you have been led to believe that there is a differant perception to two types of water ,in reality it is just what it is the temp will stay the same if you believe it so.the human mind is very powerfull yet easily duped.all things have their very own harmonic signature.one drop is and sounds differant from any other.

Just go splash some and find out.

it depends on how hot the water is

NO. I don't think so...
