Fully Reversing the Shoebox Image Source Method: From Impulse Responses to Room Parameters

Autor: Sprunck, Tom, Deleforge, Antoine, Privat, Yannick, Foy, Cédric

We present an algorithm that fully reverses the shoebox image source method (ISM), a popular and widely used room impulse response (RIR) simulator for cuboid rooms introduced by Allen and Berkley in 1979. More precisely, given a discrete multichannel

Gridless 3D Recovery of Image Sources from Room Impulse Responses

Autor: Sprunck, Tom, Privat, Yannick, Foy, Cédric, Deleforge, Antoine

Given a sound field generated by a sparse distribution of impulse image sources, can the continuous 3D positions and amplitudes of these sources be recovered from discrete, bandlimited measurements of the field at a finite set of locations, e.g., a m

Mean absorption estimation from room impulse responses using virtually supervised learning

Autor: Foy, Cédric, Deleforge, Antoine, Di Carlo, Diego

Publikováno v: Journal of the Acoustical Society of America, Acoustical Society of America, 2021, 150 (2), pp.1286-1299

In the context of building acoustics and the acoustic diagnosis of an existing room, this paper introduces and investigates a new approach to estimate mean absorption coefficients solely from a room impulse response (RIR). This inverse problem is tac

Estimation jointe des profils d’absorption des parois d’une salle à partir de réponses impulsionnelles

Autor: Dilungana, Stéphane, Deleforge, Antoine, Foy, Cédric, Faisan, Sylvain

L’estimation jointe et in situ des profils d’absorption des parois d’une salle reste à ce jour un problème inverse ouvert dans le domaine de l’acoustique du bâtiment. L’objectif des travaux menés est de proposer une méthode permettant
