Multi-frequency sound production and mixing in graphene

Scientific Reports, 2017
The ability to generate, amplify, mix and modulate sound in one simple electronic device would open up a new world in acoustics. Here we show how to build such a device. It generates sound thermoacoustically by Joule heating in graphene.

Bidirectional surface scattering coefficients

Acta Acustica
The prediction and modeling of sound propagation rely heavily on accurate representations of surface scattering. Traditional scattering coefficients, often based on random-incidence assumptions, fail to capture the directional dependence of sound ...

Optimal sensor placement for the spatial reconstruction of sound fields

EURASIP Journal on Audio, Speech, and Music Processing
The estimation sound fields over space is of interest in sound field control and analysis, spatial audio, room acoustics and virtual reality. Sound fields can be estimated from a number of measurements distributed over space yet this remains a ...
