Vapor compression and energy dissipation in a collapsing laser-induced bubble
Mohamed Farhat, Danail Obreschkow, Davide Bernardo Preso, Armand Baptiste Sieber
The composition of the gaseous phase of cavitation bubbles and its role on the collapse remains to date poorly understood. In this work, experiments of single cavitation bubbles in aqueous ammonia serve as a novel approach to investigate the effect of the ...
Melville2024Laser Doppler Vibrometer measurements of the 3D pressure field for the estimation of the radiation force produced by an acoustic standing-wave levitator
Acoustic levitation devices use powerful ultrasonic standing waves to levitate objects in mid-air. We have created a system and method to measure the full harmonic content of the acoustic field accurately. Our study revealed that levitated particles alter ...
Elsevier Science Sa2024Auditory externalization of a remote microphone signal
Vincent Pierre Olivier Grimaldi
A remote microphone (RM) system can be used in combination with wearable binaural communication devices, such as hearing aids (HAs), to improve speech intelligibility. Typically, a speaker is equipped with a body-worn microphone which enables to pick up th ...
EPFL2022Good Vibrations and Unknown Excitations
Dalia Salem Hassan Fahmy El Badawy
Inspired by the human ability to localize sounds, even with only one ear, as well as to recognize objects using active echolocation, we investigate the role of sound scattering and prior knowledge in regularizing ill-posed inverse problems in acoustics. In ...
EPFL2020Low frequency sound field reconstruction in a non-rectangular room using a small number of microphones
An accurate knowledge of the sound field distribution inside a room is required to identify and optimally locate corrective measures for room acoustics. However, the spatial recovery of the sound field would result in an impractically high number of microp ...
