Through the sound barrier without a boom?
Supersonic aircraft might not be plagued by the problem of sonic boom if a radical design proposal by a Cambridge academic could be made to work. Professor John Ffowcs Williams, Master of Emmanuel College Cambridge, directed the Concorde Noise Panel in the 1960s and 70s. He now believes it is possible to build an aeroplane that could pass through... view more... (2002-05-27)
Oxford research furthers understanding of 'Foreign Accent Syndrome'
Oxford neuropsychologists have located some very small lesions in the brain which can lead to a rare speech disorder known as Foreign Accent Syndrome. This condition, which is usually the result of a stroke or head injury, makes patients change their pronunciation to sound like non-native speakers. The finding is a further piece in the puzzle... view more... (2002-10-03)
One membrane, many frequencies
Modern hearing aids, though quite sophisticated, still do not faithfully reproduce sound as hearing people perceive it. New findings at the Weizmann Institute of Science shed light on a crucial mechanism for discerning different sound frequencies and thus may have implications for the design of better hearing aids. view more (2007-03-28)
A sound way to turn heat into electricity
University of Utah physicists developed small devices that turn heat into sound and then into electricity. The technology holds promise for changing waste heat into electricity, harnessing solar energy and cooling computers and radars. view more (2007-06-04)
Looking forward to better travel
These were the findings of a study published today, Monday 15 November, in the British Journal of Psychology, by Mark Turner of Portsmouth University, and Professor Michael Griffin of Southampton University's Institute of Sound and Vibration Research. view more (1999-11-15)
Sense and sensibility in short-term memory
More than three centuries ago, Sir Isaac Newton reflected on the similarities between the sense of hearing and the sense of sight. Newton's speculations were impossible to test scientifically, until now. view more (2007-02-20)
Magnetic field uses sound waves to ignite sun's ring of fire
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse, according to research funded by the National Science Foundation (NSF) and NASA. view more (2007-05-30)
Vampire bats recognise their prey's breathing
Vampire bats, the only mammals to feed exclusively on blood, including human blood, recognize their prey by the sound of its breathing. view more (2006-06-19)
UK researchers aim to create black holes in the lab
Physicists in the UK are planning pioneering experiments to create tiny, artificial black holes in the laboratory which will be able to suck in light or sound waves. The researchers hope that the desk-top black holes will provide important information about the fundamental behaviour of matter and energy and help to resolve some of the apparent... view more...

Study Compares Sound from Exploding Volcanoes with Jet Engines
New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. view more (2009-04-09)
Auditory neurons in humans far more sensitive to fine sound frequencies than most mammals
The human ear is exquisitely tuned to discern different sound frequencies, whether such tones are high or low, near or far. But the ability of our ears pales in comparison to the remarkable knack of single neurons in the brain to distinguish between the very subtlest of sound frequencies. view more (2008-01-11)
Computer graphics researchers simulate the sounds of water and other liquids
Splash, splatter, babble, sploosh, drip, drop, bloop and ploop! Those are some of the sounds that have been missing from computer graphic simulations of water and other fluids, according to researchers in Cornell's Department of Computer Science, who have come up with new algorithms to simulate such sounds to go with the images. view more (2009-06-08)
Stanford researchers hear the sound of quantum drums
Forty years ago, mathematician Mark Kac asked the theoretical question, "Can one hear the shape of a drum?" view more (2008-02-11)
Rare albino ratfish has eerie, silvery sheen
A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound. view more (2007-09-25)
Brain's magnetic fields reveal language delays in autism
Faint magnetic signals from brain activity in children with autism show that those children process sound and language differently from non-autistic children. view more (2008-12-01)
Low-pitch treatment alleviates ringing sound of tinnitus
For those who pumped up the volume one too many times, UC Irvine researchers may have found a treatment for the hearing damage loud music can cause. view more (2007-02-15)
A straightforward solution
A new kind of wheelchair has been developed at the University of Cambridge for people who have lost the use of one side of their body through a stroke or accident. The chair allows users to propel themselves forwards in a straight line using their active hand, and to steer themselves using their active foot. Lucy Porter, a final year student in... view more...

How a locust's eardrum could lead to tiny microphones
Being able to hear the smallest of noises is a matter of life or death for many insects, but for the scientists studying their hearing systems understanding how insect ears can be so sensitive could lead to new microphones able to capture and analyse extremely faint sounds. view more (2006-03-31)
NJIT professor's research suggests changes in underwater data communications
An NJIT professor, who has discovered new communication channels in underwater environments and invented a technique to communicate data through these channels, will be honored later this month by the New Jersey Inventors Hall of Fame. view more (2008-10-15)
A Neural Mosaic of Tones
The brain filters what we hear. It can do this in part because particular groups of neurons react to specific frequencies of sound. view more (2006-06-23)
