An intelligent artificial throat with sound-sensing ability based on laser induced graphene

open access: yesNature Communications, 2017
Traditional sound sources and sound detectors are usually independent and discrete in the human hearing range. To minimize the device size and integrate it with wearable electronics, there is an urgent requirement of realizing the functional integration ...

Objects that Sound

European Conference on Computer Vision, 2017
In this paper our objectives are, first, networks that can embed audio and visual inputs into a common space that is suitable for cross-modal retrieval; and second, a network that can localize the object that sounds in an image, given the audio signal ...

Scattering of Sound by Sound

The Journal of the Acoustical Society of America, 1955
Calculations and measurements are reported of the summation and difference frequency components which are scattered from the interaction region of two sound beams in air intersecting each other at right angles.

Absorption of Sound by Sound

The Journal of the Acoustical Society of America, 1973
The exact solution for first order nonlinear scattering of two plane waves of sound [J. Acoust. Soc. Amer. 29, 934 0957)] showed the scattered density to be ρs = c0−2E12+12ω1−1ω2−1(cosθ+12Λ)[sin−2(12θ)]∇2W12. The singularity at θ = 0, which occurs when the primary waves are collinear, may be removed by applying to this solution the operator {1 − exp[(|∂

On modulation of sound by sound

Journal of Engineering Physics and Thermophysics, 1997
Frequency shifts of continuous acoustic waves propagating in a medium which arise due to the effect of external acoustic disturbances arbitrarily propagating in the same medium are analyzed. An analytical dependence of the magnitude of the acoustic shift on the angle between the wave vectors of the probing and external waves is obtained.

Soundings on Soundings

BMJ, 1994
I am told that the Soundings page is fifth in the BMJ's popularity rankings behind editorials, Minerva, news, and Obituary and ahead of anything that could be classified as a serious scientific article. With 35 contributions under my belt, I have amassed a thick file of correspondence and a selection of embarrassing cuttings showing me pilloried and ...

Scattering of Sound by Sound

The Journal of the Acoustical Society of America, 1971
The debate about scattering of interaction-frequency components when two sound waves interact at a non-zero angle has not been resolved because no positive evidence of such scattering outside the interaction volume has been put forward. In this contribution, an attempt is made to review the situation in view of the available experimental evidence ...

Multiple Sound Sources Localization from Coarse to Fine

European Conference on Computer Vision, 2020
How to visually localize multiple sound sources in unconstrained videos is a formidable problem, especially when lack of the pairwise sound-object annotations. To solve this problem, we develop a two-stage audiovisual learning framework that disentangles

Sound

2015
The design, function, and reception of sound in video games comprises the content of this chapter. The topic is introduced through a brief history of video game sound and a short description of the general functions of video game sound, and this is followed by a more detailed description of the functions of dialogue, music, sound effects, and ambient ...

Scattering of Sound by Sound

The Journal of the Acoustical Society of America, 1957
Owing to the inherent nonlinearity of the equations of motion for a perfect fluid, two or more sound waves passing through a common region will, in general, interact with one another and give rise to scattered waves. In this paper, a source function is obtained for the lowest order scattering process which is quadratic in the primary field variables ...
