Nanopores underlie our ability to tune in to a single voice
Even in a crowded room full of background noise, the human ear is remarkably adept at tuning in to a single voice—a feat that has proved remarkably difficult for computers to match. A new analysis of the ...
Sonata in LHCb: The sound of antimatter (w/ Video)
In a recent paper the LHCb collaboration at CERN observed two particles changing from matter into antimatter and back again. Now the collaboration has turned that data into sound, so that you can listen to the music of antimatter.
Crickets' calling song hits the high notes
(Phys.org) —Research has detailed how acoustic communication has evolved within a unique species of cricket which exploits extremely high frequency harmonics to interact.
Hearing the Russian meteor, in America: Sound arrived in 10 hours, lasted 10 more
(Phys.org) —How powerful was February's meteor that crashed into Russia? Strong enough that its explosive entry into our atmosphere was detected almost 6,000 miles away in Lilburn, Ga., by infrasound sensors – a full ...
Researchers measure cavitation noise in trees
Researchers learn mechanism of hearing is similar to car battery
(Phys.org)—University of Iowa biologist Daniel Eberl and his colleagues have shown that one of the mechanisms involved in hearing is similar to the battery in your car.
For elephants, deciding to leave watering hole demands conversation
In the wilds of Africa, when it's time for a family of elephants gathered at a watering hole to leave, the matriarch of the group gives the "let's-go rumble"—as it's referred to in scientific literature—kicking ...
Blind cavefish use teeth to find their way, research shows
(Phys.org)—In a single cave in Ecuador, a species of cavefish has evolved to do something perhaps unique to them, navigate with their teeth.
Tuning in to a new hearing mechanism
More than 30 million Americans suffer from hearing loss, and about 6 million wear hearing aids. While those devices can boost the intensity of sounds coming into the ear, they are often ineffective in loud environments such ...
Ear bones reveal spawning secrets of Lake Erie walleye
Ecologists have long believed that fish tend to return to the same river where they hatched in order to spawn. But researchers at Ohio State University have determined that the old rule doesn't always apply ...
New research demonstrates humans' right ear preference for listening
We humans prefer to be addressed in our right ear and are more likely to perform a task when we receive the request in our right ear rather than our left. In a series of three studies, looking at ear preference ...
Loudspeakers in jet engines
Unless one is attending an aeronautics convention or going on a trip, noise associated with aircraft engines is rarely tolerable. Different means of significantly reducing that noise are being tested by EPFL's Electromagnetics ...
Bioengineered ears win first place at World Technology Summit
A method for bioengineering living human ears garnered a first-place award at the World Technology Summit in New York City, Nov. 15.
How an objective audiometric test can become even more reliable
Not only can the human ear detect sounds, it can also generate them. If the ear hears the two upper tones of a major triad, it produces the fundamental of the chord which can then be measured. This phenomenon, ...
