Between birth and seven months of age, the average baby born into a two-parent household hears nearly three times as much babbling, cooing and sing-song questions-and-answers from a woman -- generally the mother -- than from a man, new research shows.
(Phys.org) —A team of researchers with members from Germany, the U.S. and Austria has found that male hermit thrush appear to sing following a harmonic series similar to the way humans produce music. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they studied bird songs recorded by various people over the past half century and then compared the way the birds sang to the way people create music.
(University of Vienna) The songs of the hermit thrush, a common North American songbird, follow principles found in much human music -- namely the harmonic series. Researchers from the University of Vienna, Austria, the Cornish College of the Arts, USA, and the Philipps University of Marburg, Germany, are the first to demonstrate note selection from the harmonic series in a non-human animal using rigorous analytical methods. The study is published in the scientific journal Proceedings of the National Academy of Sciences.
Every year, nearly 4,000 children go to emergency rooms after swallowing button batteries—the flat, round batteries that power toys, hearing aids, calculators, and many other devices. Ingesting these batteries has severe consequences, including burns that permanently damage the esophagus, tears in the digestive tract, and in some cases, even death.
Harman, an audio and infotainment company, has something called HALOsonic in its product line, for noise management, which it co-developed with Lotus Engineering. The company is expanding its noise management capabilities for eliminating road noise, as a way to improve the driving experience so that drivers and passengers can look forward to a quieter ride.
Richard Branson's Virgin Galactic company is reeling from the loss of SpaceShipTwo, which crashed in California's Mojave desert on Friday, killing one of its pilots and seriously injuring the other. Branson, a billionaire business mogul whose Virgin group of companies have ranged from music to airlines to mobile phones, founded Virgin Galactic ten years ago with the aim of offering flights to the edge of space for anyone who could pay the $250,000 price tag. The future of Virgin's commercial suborbital flight program is unclear in the wake of the tragic accident.

Baby birds can discriminate sounds from different birds inside the egg—only the second species known to do so, a new study reveals.
The soundtrack to a wild rhinoceros’s life is wind passing through the savannah grass, birds chirping and distant animals moving across the plains. But a rhinoceros in a zoo listens to children screaming, cars passing and the persistent hum of urban life. A group of researchers believes that this discrepancy in soundscape may be contributing to rhinos’ difficulties thriving and reproducing in captivity.

Can scientists read the mind, picking up inner thoughts? Interesting research has emerged in that direction. According to a report from New Scientist, researchers discuss their findings in converting brain activity into sounds and words. Their study, "Decoding spectrotemporal features of overt and covert speech from the human cortex," was published in Frontiers in Neuroengineering, an open-access academic publisher and research network.
Patients with tinnitus hear phantom noise and are sometimes so bothered by the perceived ringing in their ears, they have difficulty concentrating. A new therapy does not lessen perception of the noise but appears to help patients cope better with it in their daily lives, according to new research.
Nearly 5 percent of U.S. children may be affected by fetal alcohol spectrum disorders (FASD), according to a new study. FASD are a group of conditions that can occur in the children of mothers who drank alcohol during pregnancy. Characteristics are both physical and cognitive and can include abnormal facial features, smaller-than-average physical growth, poor coordination, learning disabilities and vision and hearing problems.

The Swainson's warbler (Limnothlypis swainsonii) is one of the rarest and most secretive songbirds in North America, prized by birdwatchers in the southeastern U.S. hoping to catch a glimpse of it in the wild or hear its beautiful ringing song. With only 90,000 breeding individuals sparsely distributed across 15 states in the U.S., the Swainson's warbler is a species of high conservation concern that, for decades, has left conservationists with little confidence that its populations would ever be fully secure.
In order to create a competitive and sustainable transport system, the EU must look to alternative fuels to replace or complement petrol and diesel. Not only will this reduce transport emissions but it will also improve air quality and noise levels in urban areas. With this in mind, the ZEEUS ('Zero Emission Urban Bus System') project is working to make electric buses a core part of the urban bus network.
A windowless airplane sounds like a claustrophobic nightmare. A windowless airplane with OLED displays, aura-enhanced with subtle cabin lighting from gently glowing walls could be quite something else. Using OLED (organic light emitting diode) technology, thin, bendable, lightweight display screens would blend with the fuselage and surfaces, such as seatbacks. Use of this concept would optimize space and reduce the weight of the aircraft.
Is it possible that hearing loss in one infant from a pair of twins can affect the mother’s speech to both infants? A new acoustics study zeroes in on this question and suggests that not only is this alteration of speech entirely possible, but that mothers speak to both infants as if they are hearing impaired.
When listening to the Earth, what clues can seismic data reveal about the impact of urban life? Although naturally occurring vibrations have proven useful to seismologists, until now the vibrations caused by humans haven’t been explored in any real depth. Researchers have described their efforts to tap into an urban seismic network to monitor the traffic of trains, planes, automobiles and other modes of human transport.
