Researchers from Keio University Global Research Institute successfully generated orbital currents using sound waves, establishing a foundation for integrating acoustic technology with orbitronics. The discovery paves the way for next-generation electronic devices.
Researchers Joe Wolfe and John Smith studied the didjeridu's performance techniques, finding that a player's vocal tract plays a significant role in producing unique sounds. By analyzing acoustic impedance spectra, they identified traits of expertly played didjeridus and explored advanced techniques used by musicians.
VIRTUOSO, developed by Dr. Hyunkook Lee from the University of Huddersfield's Applied Psychoacoustics Lab, enables immersive 3D audio without loudspeakers through binaural technology powered by ASPEN. This technology simulates the ambience and reflections found in a room with headphones, allowing for accurate translation to real speakers.
Researchers characterize material properties of IP-Q using Raman spectroscopy and nanoindentation, revealing elastic parameters and their effects on acoustic behavior. The study optimizes elastic parameters for TPP-fabricated structures, benefiting applications in life science, mobility, and industry.
Scientists at the University of Tsukuba have developed a theoretical model to describe the motion of ultrasound waves in liquids containing multiple bubbles, which may enable advances in diagnostic and therapeutic applications of ultrasound technology. The new equations can also be used to enhance microbubble-enhanced medical applicati...
Researchers from Tongji University and The Hong Kong Polytechnic University developed a compact broadband acoustic absorber using imperfect components with low absorption peaks. By modulating the coherent coupling effect, they achieved quasi-perfect absorption across a broad frequency range (870 - 3224 Hz) with an average coefficient o...
