Two more pings have been detected by the Australian ship Ocean Shield in the search for flight MH370.
Air Chief Marshal (ret) Angus Houston, the head of the search's Joint Agency Co-ordination centre, announced the "promising" development during a press conference in Perth on Wednesday afternoon.
It revives hope the missing Malaysia Airlines plane's black box is still transmitting data days after its batteries were due to run dead.
Mr Houston said expert data analysis on previously detected signals had found they were not of natural origin, further boosting hopes of a breakthrough.
Mr Houston said experts believed the signals were consistent with those of a flight data recorder.
He said the first two pings - detected on April 5 at 4.45pm and at 9.27pm Perth time - had been analysed by the Australasian Joint Acoustic Analysis Centre, based at HMAS Albatross in Nowra, on the NSW south coast.
''The analysis determined that a very stable, distinct and clear signal was detected at 33.331 kilohertz, and that it consistently pulsed at a 1.106-second interval,'' Mr Houston said.
''They therefore asses that the transmission was not of natural origin, and was likely sourced from specific electronic equipment. They believe the signals to be consistent with the specification and description of a flight data recorder.''
He said two latest pings were detected on April 8 - at 4.27pm and 10.17pm, Perth time.
