Of what youre looking for. you can try to filter every other kind of sound out, and focus on exactly what you know you would have, had you found an actual pinger. >> but you heard angus houston if that news conference saying that they need to minimize ship noise. listen, they need the "ocean shield," a very big ship. they need the other ship, i cant remember the name of it, the chinese ship. and how can they do that without having the ship? they turn the motors off, but they need to have the ele...

Youre watching cnn. im brooke baldwin. the u.s. navys tpl is scouring, and now a narrow section of the indian ocean. the search area is smaller thanks to the two possible black box pings which with are now guiding the search. so far, theyve been unable to find another ping. one of the reasons is the ocean is actually such a noisy place. other sounds under the surface could be drowning out any other signals coming from those key data recorders. flores took a pinger out on the water to show us som...

Can travel 2 1/2 nautical miles. cliffs and vegetation can get in the way limiting that distance. before any beacon is shipped from here its sound output is measured in one of these huge 50,000 gallon tanks. its lowered into the tank through the floor above. surround by hydrophones, ultrasonic readings are recorded on this computer. this pinger is twa flight 800 which went off the coast of new york back in 1996. this company made the pinger. after it was recover they got it back. this one was fo...

>> youre sure? >> im positive. you can see how that does to it. ill turn it down a little bit so we can talk. the frequency is 37.5. thats the standard frequency. why was that chosen? >> this is an actual pinger like in the plane, as i said. 37.5 kilohertz. thats a frequency that not many things in nature makes that frequency. therefore, its going to be pretty quiet. the ocean is very noisy. sounds travels much better through water than air because its a denser median. that means the sound can t...
