why the voice of the duck is does not have an echo?

You read that on a Snapple cap, didn't you.\n\n"A duck's quack doesn't echo" is a much quoted scientific myth. In spring 2003 it was quoted on Home Truths on BBC Radio 4 and Shooting Stars on BBC 2. You can listen to our sound files on Home Truths by going to the BBC4 web site and "listening again". Recently, Salford Acoustics was the source of the story being presented in the national and international media when we proved that a duck's quack does echo as part of the British Association Festival of Science.\n\nClick here to hear Daisy getting into the Christmas spirit (mp3 player needed and a suspension of musical taste)\n\nSo what is an echo, and does it happen to a duck's quack?\n\n\n\nTrevor and daisy (from right to left) \n(c) Manchester evening news\n\nWhat is an echo?\nAn echo is a loud sound reflection that arrives late and so is heard as a separate sound source. Echoes can sometimes be heard in large concert halls, for example. Sound takes a long time to travel from the stage to the rear wall of the concert hall, if a strong reflection comes back from the rear wall to the front of the hall, this can be heard as an echo. To prevent this problem, it is common to apply diffusers to disperse the sound. Another common place to hear echoes is in some railway stations, making announcements hard to understand.\nThe term echo also refers to the physical sending back of sound or other waves and the repetition of sound by reflection.\n\nThe right hand animation needs a flash player.

Actually, no it doesn't. The sound you hear is actually vibrations in your ear that your brain converts to noise. So if there are no living creatures with ears and brains around to 'hear' it, it does not make a noise...just some air vibrations going all over the place.

Do you have a microphone enabled that is picking up the sound from the speakers - only to play it again as an echo? If so, mute / unplug the mic - or at least decrease the snsitivity\n\nIf you have a "software surround sound" option, tun it off- they are sometimes so horribly bad they just sound like an echo chamber gone wrong.\n\n\nMain suspect - is microphone

the picture is on Yahoo.\n\nbut it's just a coincidence, an artifact on the x-ray.  Probably something the duck ate, or an egg, or something.\n\nWhy?\n\n1. Ducks are vegetarians, and would not swallow an alien head even if they could.\n\n2. X rays do not show skulls as smiley faces.\n\n3. The alien would have to be about 8 inches tall.\n\n4. It looks more like a kitten!

No, it's not true.  The echo is difficult to detect, however, because ducks usually quack twice or more in quick succession, so it's hard to tell the difference between the quack and the echo.

Yahoo hasn't updated the Mac version in almost 3 years, so it doesn't support voice.  Until Yahoo decides to pay a little bit of attention to the growing Macintosh community, we won't see an update for a while.

Mmm, this is a tricky one as the voice isn't officially listed anywhere. It sounds a lot like Vin Diesel but I've also heard it was the director himself, Luc Besson, or even his actor pal Jean Reno. The truth is out there somewhere!

yes, just because nobody hears it doesnt mean it wont make a sound.

In Duck Hunt in particular for the original NES The gun is really a kind of cheapass camera that looks for the ducks to flash when you pull the trigger. The ducks flash within a square. The threshhold brightness is not being reached, or the code for the duck is not able to refresh on the plasma screen fast enough to signal the gun.\n\nDuck A might be:\n. ...\n\nDuck B might be:\n.. ..\n\nDuck C might be:\n... .\n\nHow many ducks can there be?\n\nYou may be able to check if it's a brightness issue by holding it right up to the screen.

Echo is a problem when your partner's speaker volume is too high. What happens is that the sound is redirected back in the microphone -- and you hear yourself talk.\n\nCouple of solutions:\n\n1) Ask your communication partner to lower speaker volume\n2) Purchase a headset or USB Phone with Echo Cancellation - http://www.amperordirect.com/c/c-internet-phones/index.html\n\nHope that helps

Everyone in Stewie's family can hear him, but the interpert what he's saying differently from what he's actually saying.\nFor example when he tells Lois to"Go to hell" all she hears is a whining baby.( don't know why, just answering the question.)

I believe this is something to do with the media file you are playing. At times when you do not have the proper codec installed, you won't get any sound. To learn more about CODECS, you can visit this link: http://www.moviecodec.com/
