A magnetically actuated acoustic metamaterial
Space coiling acoustic metamaterials are static and require manual reconfiguration for sound-field modulation. In a new report published in Communications Materials, Christabel Choi, and a team of scientists in computer science and engineering in the.....»»
Study: Consumers associate higher-pitched commercials with healthier food products
A team of researchers from Nanyang Technological University, Singapore (NTU Singapore) studying how the acoustic and visual composition of advertisements impact perceptions, has found that consumers associate a higher frequency "sonic logo" with heal.....»»
Acoustic black holes as noise traps in wooden structures
Research is currently being completed at Empa on a world-first in the sound insulation of wooden buildings. Using a physical theory from the 1990s and the tools of digitization, a research team has developed new floor elements made of solid wood pane.....»»
Study shows how people perceive gender through speech
Using terminology such as "female" and "male," or "feminine" and "masculine" affects how people perceive gender when hearing someone's voice, according to a study from researchers at the Acoustic Phonetics and Perception Lab (APPL) at NYU......»»
Magnets Made By Soil Bacteria Offer Hope For Breast and Prostate Cancer
An anonymous reader quotes a report from The Guardian: Scientists are developing magnetically guided microscopic projectiles that can be injected into patients' blood to attack breast, prostate and other tumors. The project -- led by researchers at S.....»»
Scientists Try Injecting Tumor-Fighting Viruses Coated in Magnets Made By Soil Bacteria
To attack tumors, the Guardian reports, "scientists are developing magnetically guided microscopic projectiles that can be injected into patients' blood." The project — led by researchers at Sheffield University — builds on progress in t.....»»
Metamaterial significantly enhances chiral nanoparticle signals
The left hand looks like the right hand in the mirror but the left-handed glove does not fit on the right hand. Chirality refers to this property where the object cannot be superimposed on to the mirror image. This property in molecules is an importa.....»»
Spacecraft navigation uses X-rays from dead stars
The remnants of a collapsed neutron star, called a pulsar, are magnetically charged and spinning anywhere from one rotation per second to hundreds of rotations per second. These celestial bodies, each 12 to 15 miles in diameter, generate light in the.....»»
Space-based system using GPS satellites could warn of incoming tsunamis
Initial tsunami waves are typically a few centimeters high, but nonetheless cause a disturbance in the Earth's upper atmosphere by pushing up air and creating an acoustic wave that is amplified as it goes higher......»»
Balloon Detects First Signs of a "Sound Tunnel" in the Sky
Atmospheric analog to ocean's acoustic channel could be used to monitor eruptions and bombs. From a report: About 1 kilometer under the sea lies a sound tunnel that carries the cries of whales and the clamor of submarines across great distances. Ever.....»»
Nike shoes didn’t just inspire these acoustic panels, they are the panels
Fluffy material from old Nikes is going into high-end acoustic paneling. Before founding his own studio, Michael DiTullo worked for nearly a decade designing shoes for Nike, Jordan, and Converse. So perhaps it should come as little surprise that when.....»»
Nuclear reactor power levels can be monitored using seismic and acoustic data
Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study published in Seismological Research Letters......»»
Acoustic propulsion of nanomachines depends on their orientation
Microscopically tiny nanomachines which move like submarines with their own propulsion—for example in the human body, where they transport active agents and release them at a target: What sounds like science fiction has, over the past 20 years, bec.....»»
Decoding pig emotions with a machine learning algorithm
We can now decode pigs' emotions. Using thousands of acoustic recordings gathered throughout the lives of pigs, from their births to deaths, an international team of researchers is the first in the world to translate pig grunts into actual emotions a.....»»
How to make a sound wave spin? Hit it with a pipe
Spinning sound waves open up new possibilities for acoustic traps and tricks. Enlarge (credit: Wikipedia) It's a question I'm sure was keeping you up at night: can you make an object spin with a sound wave? The answer, general.....»»
KEF’s Reference, Blade speakers updated with metamaterials
KEF promises these new versions of its speakers will have even better sound quality thanks to the use of Metamaterial Absorption Technology......»»
Study introduces the intrinsic superconducting diode effect
In 2020, Prof. Teruo Ono and his colleagues at Kyoto University reported the very first observation of a magnetically controllable, superconducting diode effect in an artificial superlattice. Their findings, published in Nature, paved the way for oth.....»»
The first topological acoustic transistor
Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics. Researchers are especially interested in using these materials as transistors, the.....»»
Combining acoustic detection and AI analysis technology to predict repairs and maintenance
Genius Holdings, a company who first specialized in spirometry systems and has a rich experience in ultrasonic intensity detection technology, partnered with AstraZeneca Taiwan to release the Healthy Lung Taiwan app. A year after releasing its spirom.....»»
Sounding off on Seattle Space Needle renovation
The Seattle Space Needle, a city landmark for nearly 60 years, recently underwent a renovation to enhance the visitor experience. Acoustic designers were tasked with ensuring that the new design is a quiet one......»»
Meet the Cyberpunk Albatrosses Scanning for Secret Explosions
