Speed of sound is 330ms^ -1 then how  we are speaking in phone for a several thousands of kilometer per sec?

Dude, Sound travellin thru air is 'different' from the digital sound that goes thru ur phone!

One billionth of a second.

well friend i am using the same service in Germany and it is not a excellent service for phone for professional purpose but for home use this speed is ideal. u will find some destruction in sound some times only.

Light travels at 186,000 miles per second, or 300,000 kilometers per second.

speed of light = 299,792,458 m/s\nspeed of sound at sea level = 340.29 m/s\nspeed of electricty = probably around 8.4 cm/hour\n\nBut wait...why is electricity so slow?! Light bulb turns on almost instantly! \nAnswers here: http://www.discoverycentermuseum.org/experiments/272.htm

Is the speed at which it travels.

CELLULAR PHONES OPERATE AT ABOUT 850 MHZ.\n\nPCS PHONES OPERATE AT 1800-1900 MHZ.

no it just sounds fast

yes faster than I can say it forwards\n\n\nzyxwvutsrqponmlkjihgfedcba

the speed = distance/time

Mach is speed of sound, so M3 is ~2200 mph.\n\nYou could hear your voice because we hear our own vioce partially through internal resonance, which would not be affected by external velocity.

Per minute - if it's a mobile.

That depends on your connection speed and the quality of the sound.\n\nThe telephony standard for voice quality audio requires 64kbps.  That's not too much, and any decent application will compress this to take up much less bandwidth than that.\n\nSo, even at 32-48 kbps, that's a fraction of a lower level broadband connection (500 kbps - 1,000 kbps).\n\nIf you're using DSL limited to an upstream link of 128 kbps, you might notice some problems with uncompressed audio, especially if you're using other internet applications at the same time.

Yes, the radio is also going to be traveling at the speed of sound because it is in the car or whatever you are in. Therefore the radio is stationary relative to you, so it makes no difference how fast you are going. If you were going away from the radio you would not be able to hear it.

The frequency range is generally accepted to be 20 Hz to 20,000 Hz. With the speed of sound = 334 m/s, 20 Hz has a wavelength of 16.7 m, 20,000 Hz a wavelength of 16.7 mm. (Ubergeek, the answerer in your link slipped a decimal place.)

when you travel faster than the speed of sound.

About 1000 feet per sec.
