Purdue findings help Coast Guard modify search-and-rescue plane
Purdue University engineers are helping the U.S. Coast Guard deal with a possible 10-fold increase in vibration that could result from installing a larger observation window in a search-and-rescue aircraft to improve visibility during missions. view more (2005-10-19)
Oohs and aahs: Vowel sounds affect our perceptions of products
Would you drive a SUV called a Himmer" Phonetic symbolism refers to the notion that the sounds of words, apart from their assigned definition, convey meaning. view more (2007-09-13)
Computer monitors wheezing in asthma patients
NWO researcher Mireille Oud is working on a computer program to evaluate the respiratory sounds made by asthma patients. It would seem that a microphone just under the Adam's apple may be sufficient to warn of an impending asthma attack. During an attack, the respiratory tract becomes narrower, leading to gradual changes in the sound made during... view more... (2001-07-26)
A "slurp" says more than ten beeps
Natural warning sounds may be the future in airplanes and perhaps in cars as well. A "slurp" when fuel is low works better than a monotonous beeping sound. In a dissertation at The Royal Institute of Technology (KTH) in Sweden, Pernilla Ulfvengren has studied how warning sounds function, how we associate sounds, and how new sounds can be... view more...

New brain findings on dyslexic children
The vast majority of school-aged children can focus on the voice of a teacher amid the cacophony of the typical classroom thanks to a brain that automatically focuses on relevant, predictable and repeating auditory information, according to new research from Northwestern University. view more (2009-11-12)
Ultra-Useful Ultrasound Causing A Stir In Materials Science
As the molecules are manipulated by the sound wave, tiny cavities are formed and destroyed inside the material that release high levels of energy when they implode, causing chemical or physical reactions to occur. Sonochemistry is already proving a useful tool and is being applied commercially in the former Soviet Union in the casting process and... view more... (1999-02-03)
Brain's 'hearing center' may reorganize after implant of cochlear device
Cochlear implants-electronic devices inserted surgically in the ear to allow deaf people to hear-may restore normal auditory pathways in the brain even after many years of deafness. view more (2007-07-24)
3D Sound Systems Using Groundbreaking Piezoelectric Springs
Piezoelectric materials such as quartz are used in digital watches and computers to produce stable vibrations at high frequencies. Polycrystaline ceramics, such as PZT (lead zirconate titanate), can be made to mimic the behaviour of these natural monocrystaline materials by polarising the crystals within the ceramic. This is done by applying an... view more... (1999-11-29)
INRIA at IMAGINA 2003, the international festival for digital images
3-6 february - Monaco. High place for digital creation, IMAGINA 2003 will be held at Grimaldi Forum and will present great names of industry and research teams of the sector. INRIA has been significantly involved in computer graphics for many years. The Institute is developing research, methods and tools in computer graphics for new sectors of... view more... (2003-02-05)
More than 80% of patients manage to stop discomfort from tinnitus and can lead a normal life again
It is estimated that between 10 and 17% of the population has suffered tinnitus at some time in their lives, according to a number of international studies. view more (2007-06-26)
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)
Sound adds speed to visual perception
The traditional view of individual brain areas involved in perception of different sensory stimuli-i.e., one brain region involved in hearing and another involved in seeing-has been thrown into doubt in recent years. view more (2008-08-12)
UMCES-led research team quantifies nutrient pollution reductions from urban stream restoration
A team of researchers led by University of Maryland Center for Environmental Science researcher Dr. Sujay Kaushal has been among the first able to quantify the amount of excess nitrogen removed from an urban stream during environmental restoration projects. view more (2008-05-01)
Caltech neurobiologists discover individuals who 'hear' movement
Individuals with synesthesia perceive the world in a different way from the rest of us. Because their senses are cross-activated, some synesthetes perceive numbers or letters as having colors or days of the week as possessing personalities, even as they function normally in the world. view more (2008-08-07)
Researcher developing new method for hearing loss assessment
A Purdue University researcher is working on a new technique to diagnose hearing loss in a way that more accurately reflects real-world situations. view more (2007-09-07)
Stanford researchers hear the sound of quantum drums

Combination treatment for migraine more effective than single medications
Combining two different types of treatment for migraine results in better symptom relief than taking either one of the medications, according to a study in the April 4 issue of JAMA. view more (2007-04-04)
Researchers study acoustic communication in deep-sea fish
An international research team studying sound production in deep-sea fishes has found that cusk-eels use several sets of muscles to produce sound that plays a prominent role in male mating calls. view more (2008-09-25)
Mathematicians find way to improve medical scans
Mathematicians at the University of Liverpool have found that it is possible to gain full control of sound waves which could lead to improved medical scans, for technology such as ultra sound machines. view more (2008-01-08)
