In the brass instrument family, the sound can be modified or attenuated using a mute, which is usually inserted in the bell of the instrument. The objective of this paper is to study the principle and the technological feasibility of an active mute using loudspeakers placed in front or around the instrument bell. This mute must reduce the acoustic ...
A number of auditory models have been developed using diverging approaches, either physiological or perceptual, but they share comparable stages of signal processing, as they are inspired by the same constitutive parts of the auditory system. We compare eight monaural models that are openly accessible in the Auditory Modelling Toolbox. We discuss t...
Nonlinear ultrasonic nondestructive testing methods have largely improved early crack detection in solid materials. However, the nonlinear signature of the crack can be difficult to measure. In this paper, to overcome this drawback, we present a parametric optimization to automatically find the best driving frequency which maximizes the nonlinear s...
The presence of natural elements in the urban environment improves wellbeing. Comparisons of different psychophysiological reactions to both auditory and visual perceptions of urban environments are employed as a method for shedding light on the mechanisms involved in audiovisual interaction, by which visual context influences auditory perception, ...
An homogenized model is proposed for linear waves in 1D microstructured media. It combines second-order asymptotic homogenization (to account for dispersion) and interface correctors (for transmission from or towards homogeneous media). A new bound on a second-order effective coefficient is proven, ensuring well-posedness of the homogenized model w...
Surrogate models are data-based approximations of computationally expensive simulations that enable efficient exploration of the model's design space and informed decision-making in many physical domains. The usage of surrogate models in the vibroacoustic domain, however, is challenging due to the non-smooth, complex behavior of wave phenomena. Thi...
The use of Machine Learning (ML) has rapidly spread across several fields, having encountered many applications in Structural Dynamics and Vibroacoustic (SD&V). The increasing capabilities of ML to unveil insights from data, driven by unprecedented data availability, algorithms advances and computational power, enhance decision making, uncertainty ...
Le concept de sound zones vise à reproduire le plus fidèlement possible un champ sonore dans une région de l’espace généralement appelée bright zone tout en diminuant le niveau sonore dans une autre région de l’espace appelée dark zone. Cette capacité à reproduire des contenus audio indépendamment les uns des autres, en différents points de l’espac...
Les salles semi-anéchoïques sont utilisées en recherche et pour la caractérisation acoustique de produits industriels. La réalisation de ces salles implique actuellement des infrastructures lourdes et des revêtements absorbants onéreux. L'objectif du projet Dôme Anti-Diffraction Acoustique (DADA) est de montrer qu'il est possible de réaliser une sa...
