Other words the sounds dont occur in nature. so theres a good chance, our experts are saying that there is something down there. >> tom, these signals detected by an australian naval vessel, but yesterday there was a chinese vessel that people didnt recognize so much. is it possible they could have been detecting the same thing? >> no. unless something really, really strange is happen, this cant be the same thing, not in that period of time, lets take a look at these act tus -- theres amount of ...

Is talking and youre better at explaining it. >> well, weve got the pinger to try to locate the most valuable piece of evidence that we have with the most information. both the cockpit voice recorder and the data recorder. as far as the voice recorder, we can certainly determine who is speaking because there are four discreet channels. one for the pilot, one for the co-pilot, one for the cockpit area microphone which picks up all of the sounds within the cockpit. whether theyre human voices or e...

Underwater sounds heard at three sites in the indian ocean, two of them very close together. the question now, were they from the flights missing pinger? a chinese ship detected pulse signals on consecutive ships. an australian ship is also investigating pings it detected from the north. so lets try this again. wave been talking about this. well get to the pulse and all those things. you were saying once we do get those things, if we do get them, you said we can distinguish whether the pilot or ...

The order of a mile, maybe a little bit longer. if youre on the surface moving across this, you would take the ship directly over the pinger. you might get two hours. >> two hours of listening. if you are starting to come back over here -- >> this is only a mile. now youre much shorter. >> now its 15 minutes of listening. this is effectively if the pinger, which is in the center, deep down nin the ocean, is sending up a perfect circ circumference of cone in the signal. >> the symmetry, how the s...

Shield has detected signals consistent with those of aircraft black boxes. >> the audible signal sounds to me just look an emergency locator beacon. >> reporter: the "ocean shield" picked up two distinct pinger alerts here. these signals detected 350 miles away from an area where a chinese ship picked untwo audio signals on saturday. britons "hms echo" has been moved there to investigate. they do not believe its related to the "ocean field" find. >> id say its unlikely. but in deep water, funny ...

>> it runs a predetermined route, and records the data, and then it brings it back. in addition, others are going to be listening and trying to understand where the edges are of where you can hear and not hear the pinger, and that way you can begin to localize down and further continually further narrow the search field. then theyll put a remotely operated vehicle down that has the capability of visual cameras and that is where we may be able to see some of the main wreckage debris field. >> tha...

Voice recorder. if thats, you know, thats the sort of signals we were getting. do you want to say any more on that? >> thanks. my understanding is there were around 2,000 yards, just under 2,000 yards apart. of note, the first detection was made whilst the towed pinger locator had been retracted, so it was much, much shallower. the reason they do that is at the end of each turn, as the ship pushes around, ocean shield reverses course. if they dont retract the towed pinger, the effective movement...

Towed pinger locator. were at the manufacturers facility in maryland, the place which has made this device and also has manufactured the bluefin 21, the torpedo like device that gets sent down. the towed pinger can detect signals from two miles away. it can go down to as low as 21,000 feet below the surface of the ocean. it does have a lot of capabilities, but it has a lot of limitation as well. without a confirmed piece of wreckage, it much more difficult to find a signal. if this is indeed a s...

The manufacture says thats because the actual pinger from those black boxes became separated from the black boxes. they say the track record was excellent. if this is the black box were talking about, its an extraordinary find for this device. >> now that this technologys in place, searching for more signals, what can we expect next? this is the operations manager at williams and associates, also a retired navy captain, joining us from seattle. thank you very much for coming in. first, that chin...
