Engineering students develop a super 'space stethoscope'

Even though astronauts receive some general medical training in preparation for a stay aboard the ISS, most of them still aren't medical professionals by any means—and with the inherent difficulties of microgravity and ...

New laser-based microphone calibration system

Researchers at the National Institute of Standards and Technology (NIST) have conducted the first demonstration of a faster and more accurate way to calibrate certain kinds of microphones.

Using miniature microphones to record rat's happy squeaks

A team of neurobiologists at the University of Haifa's, Sagol Department of Neurobiology has found, via the use of novel miniature microphones, that rats make sounds when in the company of other rats for no other reason than ...

Doctoral student designs microphones that monitor road traffic

An EPFL doctoral student has designed a microphone-based system that functions as an automatic road traffic sensor. The technology can determine not just how much traffic there is, but also how fast vehicles are going and ...

Taiwan deploys undersea quake warning system

Taiwan said Monday it had put into service its first undersea seismic observation system, giving the island life-saving extra seconds or even minutes to brace for earthquakes and tsunamis.

Research team introduces wearable audio dataset

Researchers studying wearable listening technology now have a new data set to use, thanks to University of Illinois at Urbana-Champaign graduate student Ryan Corey and his team.

Amorphous metallic glass for high-sensitivity MEMS microphones

Advanced microphones using microelectromechanical systems (MEMS) are capable of supporting new user interactions with "smart" devices, like chatting with Apple's Siri, or Amazon's Alexa. The key to achieving the high sensitivity ...
