The sound of a sunset（图）
夕阳 超声工具包 声音
2023/6/20
What does a sunset sound like? Or ascending shades of red? Now you can listen in via the Sonification Toolkit, a polished, up-and-running prototype from a year-long initiative powered by the combined ...
Sound waves create whirlpools to round up tiny signs of disease
Sound waves create whirlpools tiny signs of disease
2017/2/16
Mechanical engineers at Duke University have demonstrated a tiny whirlpool that can concentrate nanoparticles using nothing but sound. The innovation could gather proteins and other biological structu...
With more than 800,000 miles of sewer pipes in the United States, wastewater utilities tasked with keeping those pipes clear have their work cut out for them.Now, a small business has developed a quic...
OSU researchers prove magnetism can control heat,sound
OSU researchers magnetism can control heat sound
2015/6/18
Phonons—the elemental particles that transmit both heat and sound—have magnetic properties, according to a landmark study supported by Ohio Supercomputer Center (OSC) services and recently published b...
In the March 23 issue of the journal Nature Materials, they describe how a magnetic field roughly the size of a medical MRI reduced the amount of heat flowing through a semiconductor by...
Circular Sound Wave Scattering Derivation for Acoustic Cloak Detection
Circular Sound Wave Scattering Derivation Acoustic Cloak Detection Classical Physics
2012/5/29
In this Letter we develop analytical formulations to describe sound scattering in lossless medium due to 2D circular wave incident on an acoustic cloak. A perfect acoustic cloak is reflectionless and ...
The Superconducting Phases of URu2Si2: Longitudinal Sound Velocity Measurements
Superconducting Phases URu2Si2 Longitudinal Sound Velocity Measurements
2012/2/27
High resolution longitudinal sound velocity measurements in a magnetic field performed in the temperature tending to zero limit reveal two distinct signatures attributable to multiple superconducting ...
Effective speed of sound in phononic crystals.
How opening a hole affects the sound of a flute
thin domains, convergence of operators, resonance, mathematics for music and acoustic.
2011/9/9
In this paper, we consider an open tube of diameter " > 0, on the side of which a small hole of size "2 is pierced. The resonances of this tube correspond to the eigenvalues of the Laplacian operator ...
Renormalized waves and thermalization of the Klein-Gordon equation: What sound does a nonlinear string make?
Renormalized waves thermalization Klein-Gordon equation
2010/11/10
We study the thermalization of the classical Klein-Gordon equation under a u^4 interaction. We numerically show that even in the presence of strong nonlinearities, the local thermodynamic equilibrium ...
Low-temperature thermodynamics of the unitary Fermi gas: superfluid fraction, first sound and second sound
Low-temperature thermodynamics unitary Fermi gas superfluid fraction
2010/11/25
We investigate the low-temperature thermodynamics of the unitary Fermi gas by introducing a
model based on the zero-temperature spectra of both bosonic collective modes and fermonic singleparticle ex...

Hail the first sound ‘lasers’（图）
the first phonon "lasers" coherent sound waves the megahertz range
2010/3/26
Two independent groups of physicists have unveiled the first phonon "lasers" – devices that emit coherent sound waves in much the same ways as lasers emit coherent light waves. Sometimes called "saser...
8 November 2006，Watch somebody munch on boiled sweets in the dark, and you might just see their mouth glow. That's because piezoelectric materials such as sugar can emit light when they are broken. No...
