Earlier today Australian Prime Minister Tony Abbott told reporters in Beijing that the search teams hunting Flight MH370 are confident the signals they have been detecting in the Indian Ocean ARE from the missing jet's black box.
He said: "We have very much narrowed down the search area and we are very confident the signals are from the black box."
An Australian vessel has on four occasions picked up signals consistent with flight recorders, officials say.
Speaking in China during an official visit, Mr Abbott said search teams needed as much information as possible from the acoustic signals before the black-box batteries ran out.
"It's [the search area] been very much narrowed down because we've now had a series of detections, some for quite a long period of time," Mr Abbott said.
"Nevertheless, we're getting to the stage where the signal from the black box is starting to fade."
He also said that officials were confident that they knew "the position of the black box flight recorder to within some kilometres".
"Still, confidence in the approximate position of the black box is not the same as recovering wreckage from almost 4.5km (2.6 miles) beneath the sea or finally determining all that happened on that flight."
The signals - if proven to be sent from the flight recorder of the missing plane - will eventually allow officials to determine an exact resting place for the downed Boeing 777.
They will then send down a submersible vehicle to plunge down to the depths of the ocean to search for the black box.
The 'pings' emitted by Flight MH370's black box are soon expected to fade, more than a month after the plane, which was carrying 227 passengers and 12 crew, disappeared on 8th March.
Despite a thorough investigation, it is still not known why MH370 strayed so far off course, after disappearing over the South China Sea between Malaysia and Vietnam.
The lives of the passengers, pilots and flight staff have been thoroughly investigated as officials consider hijacking, sabotage, pilot action or mechanical failure as possible causes.
