Hear if you put your head under water. but its not necessarily a ping. it is once per second. sounds like a bird chirping i know on my iphone if i have a lot of apps running im going to run down the battery. one or two, maybe pinged every two hours it might save on othe battery is that not the way it works. >> no, its designed to operate continuously. they might have lost the signal for a myriad of reason. the topography of the ocean floor. flight data recorder or pinger may be resting. a bunch ...

Yep. yeah? >> in attempts of locating this pinger, i mean, how big of an area -- i mean, how are you able to locate that area at this point? is it within a couple miles or a hundred miles? >> what i might do is ask one of the subject matter experts, commodore levy, to address your question, and you might just add a little bit on some of the challenges associated with the work thats being done underwater. >> i might just open with some of the challenges we face. as youve heard, most of the, all o...

The pinger in the area to locate was it within a couple miles? 100 miles? >> what i might do is ask the, one of the subject matter experts commander leafy to address your question he might add on some challenge as associated with work being done underwater. as youve heard most of the, all of the detections happening at the moment are acoustic. you can think of listening for sound, microphones. over the ping locator sitting aprochlly 3,000 meters below the ocean. unlike in air, where sound travel...

Search area down from that fast tracts of indian ocean to a much smaller three mile square box. so its a positive development that they even detected these signals in the first place. but youre right, in the next hour or so, were expecting the observation flights, a dozen or so military and civilian planes taking off mainly from this air base outside of perth because they havent let up in looking in other areas of the search zone as well. theyre still kind of looking for debris on the surface of...

There are two reporters, the cockpit voice one and flight data recorder ch each has its own. experts say that the pings would not sync up. these are not ideal conditions and that is really an understatement. plus video shows them listening with ear buds, not headsets that would block out noise. number four this is fascinating. a spare pinger on the boat could have sent the signal. its not clear why the crew had it but a black box manufacturer says if the pinger gets wet, it starts transmitting. ...

Visually looking at the ocean floor. but at the moment, thats not deployed. the focus is on trying to reacquire the acoustic signal that they had 24 hours ago. in terms of area, by the end of tomorrow when they completed their runs, they expect to have a 3x3 mile box searched. so it is a quite a small area that will be searched very thoroughly. but it is a very small area. and that gives i hope some sense of the challenges that theyre facing out there. keep in mind each of the runs they conduct ...

Field. >> really? they could have totally been confused. is that your analysis? >> we were questioning saturday, why does it seem like the australians are so slow to react to the chinese information? they say were contemplating what were going to do about this, well it seems now they must have already had something from the "ocean shield" that caused them to not quite believe what the chinese had. >> i wonder if it was a photo op for chinese consumption? we looked through that video and there wa...

Its a frequency designed to be heard not by the human ear, but by acoustic listeners. those acoustic listeners will then provide both a visual reference point, a wave form, and an audio sound which can be heard then by the ear. the pinger is not only designed for the 37.5, but the rhythmic one-second pings. theres many noises in the ocean. some of them are mammal made. others could be from other machinery. the sound -- we learned last night and over the last few days sound travels far, especiall...

Box. does it sound like it is right? >> well, the frequency is right, and the pulse rate is right. with the australian ship having had the opportunity to listen to it for two hours, two hours and 20 minutes to record it. they can upload that to the manufacturer who can definitively tell us, is that from the pinger. but this is over the last couple of days, i have become more hopeful than at any point previous in the mystery. >> lets talk about if they are

About that apparently located these signals, and also the bluefin 21, which is an autonomous underwater vehicle, both made by phoenix international, and we got access to phoenixs facilities here not far from d.c., near largo, maryland. thats their headquarters. thats where they made all of this very sophisticated equipment. the way it works that the towed pinger locator goes down and sweeps that area first. the towed pinger locator can go down as far as 20,000 feet below the surface of the sea. ...
