According to the conclusions of a new study, it would appear that the reason why early whales have abnormally-shaped head is because this enabled them to use acoustics to discover the locations of things underwater. These shapes were not merely an adaptation that occurred later on.For many years, researchers have bel... |

Using the ultra-sensitive ears of killer whales as inspiration, researchers at the Stanford University have created a new underwater microphone. Their device is significantly more responsive to sound than other similar device on the market today. One of the advantages this microphone has is that it can be used at any... |

Researchers in the United Kingdom announce the development of a new method of surveying dangerous geological areas for risks of impending landslides. The technique relies of sound interpretation to give early warnings of the looming threat.The electronic ear can listen for the subtle noises that ground layers make as... |

After tagging thousands of marine creatures with acoustical transmitters, researchers are now prepared to start using the recently-develop Pacific Ocean Shelf Tracking (POST) network, which would enable them to eavesdrop on natural oceanic activity patterns.For the past few years, about 16,000 animals have been tagge... |

Conducting head counts on various animal species is a very important aspect of biology. The data provide environmentalist groups and protection agencies with the necessary information they need to propose and sustain conservation programs. However, performing a census is not always easy. Some species prefer to remain... |

Speaking on February 21 in San Diego, at the annual meeting of the American Association for the Advancement of Science (AAAS), expert Christopher Clark, who is the I.P. Johnson director of the Cornell University Laboratory of Ornithology Bioacoustics Research Program, explained some of the challenges these intelligen... |

Everybody knows that whales communicate using very high-pitched sounds that resemble clicks. These sounds can be heard over incredibly long distances, and prove that the creatures are intelligent and able to understand each other. But this discovery, for example, was only made possible through the use of acoustic sur... |

The scientific field of acoustics – the science of sound – will get a considerable boost at the end of next month, as experts will convene at the 158th Meeting of the Acoustical Society of America (ASA). Several highlights from the planned schedule have already been made available, and it appears that som... |

Ever since micro- and nano-technology first appeared, there has been a steady strive on the part of researchers to develop ways of manipulating structures formed at such small scales. The efforts have grown considerably once experts have started realizing that nanostructures – billionths of times smaller th... |

Having to deal with clogged pipes is a very dirty and complicated business, because the clogs cannot be easily identified, and repairmen often have to take the whole installation apart, in order to look for the source of the problem. But the days of water all around the house and of high repair costs may soon go away... |

When cave tunnels collapse, the faith of the miners trapped behind is often sealed, mostly because emergency rescue teams can rarely reach the pockets where survivors are located in time, before oxygen supplies run out. In addition, drills cannot be performed with electric equipments, as any spark may cause an explos... |

The acoustical magic of the Boston Symphony Hall is due to the fact that the architectural company that built it resorted, for the first time in history, to the services of a physicist. It was built based on the design of Leipzig's Gewandhaus, which was devastated later on, during World War II. Constructed ... |
