Sounds

Hi All,

I am posting this in the middle of night, well over 1 AM (!!!!). Read an article, and just loved it.
Wanted to share it with all.

Wait a minute, finish this article before you click to view the other (!!!)

Ever wondered how sounds are produced ?
Ever wondered why we are able to hear only certain sounds and not others ?( Its because the human ear is capable of hearing only frequencies in the range of 20Hz to 20 kHz. Frequency is nothing but the number of cycles per second, or the number of repetitions per second)

Just struck by one thought..
I have heard many saying, "vaai irukkunnradukaga, enna venna pesalama? "
By nature, human ear can hear only certain frequencies.. ( a limitation)
by nature the eye can see only till the LOS (Line of Sight -again a limitation)
Whereas we can speak anything as long as we learn the language. There aren't any natural limitations.( Hmm one can ask whether we can produce sounds in the range outside of 20Hz to 20khz? Dunno the answer to that. But even if we do make it, we sure can't hear it :D )
Why is it so ? Perhaps is it to see how much of a self control we have over ourselves ?
Or perhaps whoever/whatever created us wanted us to find out for ourselves. ( Well the answer to this question of the universe , the life and everything is 42. ( Source- HitchHiker's Guide to galaxy, And the question to the answer- find out for yourself :D)

Don't wanna continue further with this mad talk. Here's the link.
Sounds. Hope you love it as much as I did :)

Ciao
