Nestling Birds Struggle in Noisy Environments

Unable to fly, nestling birds depend on their parents for both food and protection: vocal communication between parents and offspring helps young birds to determine when they should beg for food and when they should crouch in the nest to avoid a predator seeking an easy meal. A group of researchers has found that ambient, anthropomorphic noise – from traffic, construction and other human activities – can break this vital communications link, leaving nestlings vulnerable or hungry.

Urban Seismic Network Detects Human Sounds

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. Scripps Institution of Oceanography researchers Nima Riahi and Peter Gerstoft will describe their efforts to tap into an urban seismic network to monitor the traffic of trains, planes, automobiles and other modes of human transport.

Hearing Loss in One Infant Twin Affects Mother’s Speech to Both Babies

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.

Ant nests can offer a lot to organisms other than just ants. They are well-protected, environmentally-stable and resource-rich spaces -- in many ways everything a tiny creature could ask for in a home. For the insects that squat inside ant nests, though, survival means finding ways to live with the ants -- by foiling the chemical cues ants use to distinguish friend from foe, for instance.

Identifying ‘Stance Taking’ Cues to Enable Sophisticated Voice Recognition

In the future, computers may be capable of talking to us during meetings just like a remote teleconference participant. But to help move this science-fiction-sounding goal a step closer to reality, it’s first necessary to teach computers to recognize not only the words we use but also the myriad meanings, subtleties and attitudes they can convey.

Some of mankind’s earliest and most mysterious artistic achievements—including prehistoric cave paintings, canyon petroglyphs and megalithic structures such as Stonehenge—may have been inspired by the behaviors of sound waves being misinterpreted as “supernatural.”
