Box or beacon and have it turn out to be nothing? >> it certainly can happen, although typically if you get that same pulse repetition rate and frequency, thats an awfully good clue theres probably not many things that can imitate a pinger like that. >> i understand that it shares kind of the same frequency as some marine animals, though, but what distinguishes this in your mind? >> well, both the frequency, which you are correct, i understand and am not a marine biologist, some animals e met fr...

Acoustic event. authorities saying that that vessel will stay there to thoroughly investigate that occurrence. houston saying that, you know, this is raw data at this moment. it thoroughly needs to be looked at, thorough le needs to be investigated and that we are a long way off from being able to draw any conclusions from this information. natalie. >> and whats really remarkable about this the possible break through, and yes, we definitely want to emphasize this has not been verified, but it ca...

Today. and we cant really toggle between this and put on to where the ping location, but its basically below the lower box. or so. all the boxes. so theyre not planning to send -- these are the three search areas where the planes are going to be heading out. now, the best that i can see, the pinger from the chinese is somewhere where it says 2,200. >> right here? >> just a bit further up. >> right here. >> yeah. but theyre clearly not going to look over that area today. >> right. >> the planes. ...

Perspective when were talking about teeny tiny microphones looking for teeny tiny black boxes. >> they create walls. sound can baounce off it and no make it through it. put a sub right above or below one of those, and theyre shooting sound to find a sub they can bounce off the therm aa thermales and not see the sub. >> if the toe pinger locater is being towed behind the vessels in question, they have to be exactly in the right thermal layer in order to detect something? >> more or less. theres o...

Then theres that emergency beacon itself. where it is the batteries wont be good for much longer. today is day 31 since malaysia airlines flight 370 vanished. in the indian ocean right now a frantic search is under way to track down three mysterious pulse signals. two of them apparently matching the same frequency of a black box pinger. cnn aviation analyst mary schiavo, cnn aviation analyst les abend, paul ginsberg, forensic audio expert, hopefully youll become an analyst here on cnn. i would l...

370? >> good afternoon, brianna. we dont know enough yet about the information. the beacon itself, i have one with me here, produces a very repeatable, clear signal. it is a tick that happens once per second at a very fixed frequency. it doesnt stop, it doesnt start. it just is continuous. so if they recorded 90 seconds worth of audio at that frequency with that repeatable tick, then i would be very confident. so the news is very hopeful at this point. >> okay. and if i can, if you wouldnt mind ...

Aircraft. the pingers batteries are expected to die as early as this weekend. and the chinese are saying that they spotted a number of white floating objects in todays search near the investigation area. nbcs ian williams starts us off with the very latest from perth, australia. >> reporter: good day to you, craig. these reports come from chinese state media which has reporters on board the patrol ship equipped with a black box detector. theres not too much detail in the reports. all they say is...

Course, to get the actual assets that have the side scan s.o.n.a.r. and these deep sub messables that can actually then confirm. they have cameras on them. they can use the side scan s.o.n.a.r. to actually map the bottom of the ocean so we can see really where the debris field is. and then once that takes place, then determine the best course of action to try and find where the cockpit voice recorder and the flight data recorder may be. the one thing about this is that those pingers are mounted ...

Ships, high powered echo sounders operate at 30, 33 kilohertz. there are some mind hunting sonars that operate at 37 kilohertz. and, you know, weve got a lot of ships in the area. weve got some submarines. and there could be some other signal that may not be precisely 37.5 kilohertz but could be very close. and it might be confusing. so there are a lot of things that we have to think about, you know, that there are a lot of ships and airplanes in the area. you know, this may be the pinger but it...

Positive sign and it could be the jackpot. >> and miles, there is a lot of ship traffic in the southern portion of the indian ocean, so could this signal be coming from something else? >> im not an expert on underwater searching on all this, but i do know that the type of signal that they are reporting would lead you to believe that it is, in fact, the pinger for one of the black boxes. whats interesting to me is how they got to this location, what sorts of assets did the chinese use to get to t...
