Robust tunable acoustic impedance control on electroacoustic resonators for aircraft noise reduction
Air traffic noise emissions are responsible for a significant part of the overall environmental noise, especially in the vicinity of airports. Exposure to environmental noise is known to negatively impact health and to be associated with cardiovascular dis ...
EPFL2023WINC: A Wireless IoT Network for Multi-Noise Source Cancellation
Haitham Al Hassanieh, Jiaming Wang, Junfeng Guan
This paper introduces Wireless IoT-based Noise Cancellation (WINC) which defines a framework for leveraging a wireless network of IoT microphones to enhance active noise cancellation in noise-canceling headphones. The IoT microphones forward ambient noise ...
New York2023Observation of non-reciprocal harmonic conversion in real sounds
Romain Christophe Rémy Fleury, Hervé Lissek, Xinxin Guo
Reciprocity guarantees that in most media, sound transmission is symmetric between two points of space when the location of the source and receiver are interchanged. This fundamental law can be broken in non-linear media, often at the cost of detrimental i ...
2023Plasma-based Electroacoustic Actuator for Broadband Sound Absorption
Environmental noise, mostly related to human activities, has an immense impact on public health. The development of noise reduction technologies is paramount in addressing this problem. Because of practical and economic reasons, a compact, broadband, light ...
EPFL2022Corona discharge actuator as an active sound absorber under normal and oblique incidence
Hervé Lissek, Stanislav Sergeev, Thomas Humbert
In the majority of active sound absorbing systems, a conventional electrodynamic loudspeaker is used as a controlled source. However, particular situations may require an actuator that is more resistant to harsh environments, adjustable in shape, and light ...
2022Transverse Noise, Decoherence, and Landau Damping in High-Energy Hadron Colliders
High-energy hadron colliders are designed to generate particle collisions within specialized detectors. A higher number of collisions is achieved with high-quality beams of low transverse emittances, meaning a small transverse cross-section, and high inten ...
EPFL2021Emittance growth suppression with a multibunch feedback in high-energy hadron colliders: Numerical optimization of the gain and bandwidth
Xavier Buffat, Sondre Vik Furuseth
A transverse feedback system can effectively mitigate the emittance growth caused by injection oscillations and machine noise in hadron beams. However, as its action on the beam depends on beam position measurements of finite accuracy, it introduces additi ...
AMER PHYSICAL SOC2021Blind Universal Bayesian Image Denoising With Gaussian Noise Level Learning
Sabine Süsstrunk, Majed El Helou
Blind and universal image denoising consists of using a unique model that denoises images with any level of noise. It is especially practical as noise levels do not need to be known when the model is developed or at test time. We propose a theoretically-gr ...
IEEE2020Removing Structured Noise With Self-Supervised Blind-Spot Networks
Removal of noise from fluorescence microscopy images is an important first step in many biological analysis pipelines. Current state-of-the-art supervised methods employ convolutional neural networks that are trained with clean (ground-truth) images. Recen ...
IEEE2020Wave-conversion active liner based on generalized Snell-Descartes law
The Cremer’s impedance theoretical framework has been used for years to optimally design acousticliners for the aeronautic industry, such as honeycomb liners. This passive mean of sound absorption,which consists in rather thin (a few centimeters) honeycomb ...
