World's top theoretical physicists converge to consider 'future of physics'
...uditorium has been designed for the task. Fifteen microphones
in the low ceiling enable the recording of every question as well as the speaker's response. Provisions have been made for video equipment to capture not only the speaker, but also the audience. The full dynamics of intellectual interaction can now...

...nce in the time the sound arrives at the different microphones
on a SENTRI acoustic units unit. It then points a camera, turns on lights, sounds an alarm, and alerts police units. Field tests with real guns (45 cal, 38 cal, 9 mm) have shown 95% accuracy with respect to gunshot recognition, and 100% accurac...
Secrets of whales' long-distance songs are being unveiled
... as they move through the Atlantic, the underwater microphones
of the Sound Surveillance System (SOSUS) can track singing blue, fin, humpback and minke whales. From the acoustical maps he and his colleagues have obtained, Clark has come to realize that he has been thinking about whales at the wrong time scale. ...
Scientists journey to southern Africa to unravel the secret world of elephant communication
...hants were feeling the calls and not hearing them, microphones
were installed above ground so researchers could monitor all low frequency sounds in the air."The results of our 2002 study showed us that elephants do indeed detect warning calls played through the ground," O'Connell-Rodwell observes. "We expected t...
New research shows bats have complex skills to deal with 'clutter'
...gh-speed infrared cameras and strategically placed microphones
in the "Batlab," Moss's team was able to match slowed video and audio recordings of the bat's echolocation activity and corresponding movement as it pursued an insect tethered to a string. The insect could be out in the open, or nestled in among lea...
How a locust's eardrum could lead to tiny microphones

Listening to the sound of skin cancer
...However, researchers can pick them up with special microphones
and analyze them with a computer. Other human cells do not contain pigments with the same color as melanin, so the melanin signature is easy to tell apart from other noises, said John Viator, a biomedical engineer at Missouri-Columbia and a coauthor ...
Listening to gunshots may save lives and wildlands
