How to predict the sound produced by a tonewood block once carved into the shape of a violin plate? What is the best shape for the best sound? Artificial Intelligence offer answers to these questions. These are the conclusions that researchers of the Musical Acoustics Lab of Politecnico di Milano presented in a study that was recently published on Nature Scientific Reports.
University of Tsukuba researchers tested a new Nike soccer ball used in the English Premier League with a wind tunnel. They found that its aerodynamic properties make it more stable in flight, at the cost of total distance. This work may lead to improvements in sports equipment design.
Osaka University researchers studying maximally efficient packing showed that jamming transitions with random spheres follows universal rules. This work may help with industrial processes including glass annealing.
New Curtin research has found urgent action is needed to ensure man-made underwater noise in Australian waters does not escalate to levels which could be harmful to marine animals, such as whales, and negatively impact our pristine oceans.
Imaging techniques enable decisive step toward development of novel hearing prostheses
Researchers from Osaka University and JOANNEUM RESEARCH develop ultrathin piezoelectric flexible patches that harvest the body's energy to monitor the patient's pulse and blood pressure. This work may lead to novel biosensors and self-powered wearable electronics.
Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they say, could result in materials called "quasicrystals" with custom magnetic or electrical properties.
Spiders are master builders, expertly weaving strands of silk into intricate 3D webs. If humans could enter the spider's world, they could learn about web construction, arachnid behavior and more. Now, scientists report they have translated the complex structure of a web into music, which could have applications ranging from better 3D printers, to cross-species communication and otherworldly musical compositions. The researchers will present their results today at ACS Spring 2021.
Scientists have identified 200+ non-military ocean hydrophones worldwide and hope to pool their recorded data into a "2020 quiet ocean assessment" and to monitor future ocean soundscapes -- capturing the signals of whales and other marine life while assessing the noise levels of human activity. Combined with other sea life monitoring tools and methods such as animal tagging the work will help reveal the extent to which noise in "the Anthropocene seas" impacts ocean species.
According to a linguistic survey report, people often confuse the pronunciation of /hi/ with that of /si/ in the dialect of Tokyo and the Tohoku region of Japan. A team of researchers at Toyohashi University of Technology and the National Institute for Japanese Language and Linguistics (NINJAL) found that the confusion is resulted from the articulation of the tongue varying in the transverse direction while the tongue tip is positioned at the same place of articulation.
