It can be measured using gas chromatography or a chemosensory device which is sometimes called and "electronic nose."

Recently I read a news that in Japan an electronic instrument can fiil the room with tthe smell that we want.
When a rose flower is brought near that and removed away, it smells the rose and latter fills the room with that smell.
But this is capable of doing this for only limited smells.
It is hoped that soon it will be improved to smell any kind of smells.

Of corse there's a way to measure speed. Once common way is miles(or kilometers) per hour, but either variable could be changed in that like feet per second.
Light could be measured in brightness, and smells in their strengh i suppose.
As for noise, that can be measured in it's longetudinal waves. See sound travels by bumping into the particles in the air, and those into another, causing a chain reaction. I'f you've ever seen a cartoon where they try to show sound with waves with curved lines (like out of an antenna or into an ear) that represents longetudinal waves. the frequency and other variables can be measured that way with sound, or as you put it "noise"

The nature of "smell" is chemical. The different "smell receptors" actually attach to certain types of molecules. This is actually defined by the shape of the molecule. Because of this, completely different molecules with similar shapes actually have the same "smell", because they are able to react with the same receptor. We actually have a great deal of knowledge regarding these receptors and their chemical affinities, and so if we can simulate these receptors in a machine, the machine can, in effect, "smell".
In a sense (no pun intended), there are already many, many machines that can smell, because they are designed to detect certain types of chemicals.

Galileo used a flame from one element to an different and timed it, he got here out very faulty although that's the 1st recorded time somebody tried. The credit is given to a danish guy who became observing Jupiter's moons.

What an interesting question! I found the link below - maybe I'll read it myself!
