(PhysOrg.com) -- A serendipitous discovery of deaf zebra fish larvae has helped narrow down the function of an elusive protein necessary for hearing and balance. The work, led by Rockefeller University`s A. James Hudspeth, suggests that hearing loss may arise from a faulty pathway that translates sound waves into electrical impulses the brain can understand. http://www.physorg.com/news179470963.html Medicine & Health Tue, 08 Dec 2009 05:03:48 EST news179470963 A recent AFOSR-funded technology should enable the Air Force to achieve advances in object and target detection technology by using sophisticated algebraic theories called groups, rings and fields. http://www.physorg.com/news178952532.html Technology Wed, 02 Dec 2009 05:20:02 EST news178952532 Johan Wesselink of the University of Twente, The Netherlands, has developed a device to actively combat noise nuisance. This invention curtails sound waves and vibrations by producing anti-noise. The researcher is confident that his device will be used in the transport and industrial sectors within a matter of years. http://www.physorg.com/news178903738.html Technology Tue, 01 Dec 2009 15:29:47 EST news178903738 (PhysOrg.com) -- Ava Martin seems less nervous than her parents as the three sit in an audiologist`s office at UC Irvine Medical Center a few days after Labor Day. In August, the 6-year-old had surgery to place a cochlear implant in her right ear. Now Ava plays with toys while Ginger Stickney describes to Dave and Gabrielle Martin the tests that will gauge how their daughter`s auditory nerve is responding to the implant. But first Stickney must activate the device that could restore function to Ava`s right ear - an ability lost years ago due to a congenital inner-ear defect that`s also destroying the hearing in her left ear. http://www.physorg.com/news176659178.html Medicine & Health Thu, 05 Nov 2009 18:00:01 EST news176659178 (PhysOrg.com) -- Researchers at the California Institute of Technology have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space. http://www.physorg.com/news175766229.html Nanotechnology Mon, 26 Oct 2009 08:57:51 EST news175766229 Ultrasound and underwater sonar devices could "see" a big improvement thanks to development of the world's first acoustic hyperlens. Created by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory, the acoustic hyperlens provides an eightfold boost in the magnification power of sound-based imaging technologies. Clever physical manipulation of the imaging sound waves enables the hyperlens to resolve details smaller than one sixth the length of the waves themselves, bringing into view much smaller objects and features than can be detected using today's technologies. http://www.physorg.com/news175702307.html Physics Sun, 25 Oct 2009 15:12:53 EST news175702307 (PhysOrg.com) -- A clever structure in the ear of a tropical butterfly that potentially makes it able to distinguish between high and low pitch sounds has been discovered by scientists from the University of Bristol, UK. http://www.physorg.com/news175353553.html Biology Wed, 21 Oct 2009 14:29:05 EST news175353553 Every year roads are built and repaired to the tune of several billions. Intensive efforts are underway all over the world to get 'more road for your money' by developing better methods for both design and quality control of materials. One problem is that today there are no good methods for checking how robustly and safely the roads were built. Therefore they often don't last as long as they were supposed to and more money has to go to road construction. http://www.physorg.com/news172915466.html Technology Wed, 23 Sep 2009 09:20:02 EST news172915466 (PhysOrg.com) -- Music, rather than electromechanical valves, can drive experimental samples through a lab-on-a-chip in a new system developed at the University of Michigan. This development could significantly simplify the process of conducting experiments in microfluidic devices. http://www.physorg.com/news167488557.html Chemistry Wed, 22 Jul 2009 14:10:01 EST news167488557 It was an idea born out of curiosity in the physics lab, but now a new type of ‘laser` for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology. http://www.physorg.com/news164454318.html Physics Wed, 17 Jun 2009 11:20:01 EST news164454318 Revolutionary ultrasonic nanotechnology that could allow scientists to see inside a patient's individual cells to help diagnose serious illnesses is being developed by researchers at The University of Nottingham. http://www.physorg.com/news163160650.html Nanotechnology Tue, 02 Jun 2009 11:25:00 EST news163160650 (PhysOrg.com) -- A groundbreaking new loudspeaker, less than 0.25mm thick, has been developed by University of Warwick engineers, it's flat, flexible, could be hung on a wall like a picture, and its particular method of sound generation could make public announcements in places like passenger terminals clearer, crisper, and easier to hear. http://www.physorg.com/news157823827.html Technology Wed, 01 Apr 2009 16:57:30 EST news157823827 (PhysOrg.com) -- For the first time ever, a modern dance company has performed to music generated from seismic data, recorded from four volcanoes across three continents.

It is wired to a ceramic probe, called a transducer, and it creates sound waves so strong they instantly cause water to bubble, spray and turn into steam. http://www.physorg.com/news148916503.html Medicine & Health Fri, 19 Dec 2008 13:41:43 EST news148916503 Noise from commercial and military jet aircraft causes environmental problems for communities near airports, obliging airplanes to follow often complex noise-abatement procedures on takeoff and landing.
