Room impulse response reconstruction with physics-informed deep learning

1 code implementation2 Jan 2024 Xenofon Karakonstantis, Diego Caviedes-Nozal, Antoine Richard, Efren Fernandez-Grande

A method is presented for estimating and reconstructing the sound field within a room using physics-informed neural networks.

A convolutional plane wave model for sound field reconstruction

1 code implementation24 Aug 2022 Manuel Hahmann, Efren Fernandez-Grande

A suitable model can be difficult to determine when the spatial domain of interest is large compared to the wavelength or when spherical and planar wavefronts are present or the sound field is complex, as in the near-field.

Generative adversarial networks with physical sound field priors

1 code implementation1 Aug 2023 Xenofon Karakonstantis, Efren Fernandez-Grande

This paper presents a deep learning-based approach for the spatio-temporal reconstruction of sound fields using Generative Adversarial Networks (GANs).

Semi-supervised source localization in reverberant environments with deep generative modeling

In situ sound absorption estimation with the discrete complex image source method

no code implementations17 Apr 2024 Eric Brandao, William Fonseca, Paulo Mareze, Carlos Resende, Gabriel Azzuz, Joao Pontalti, Efren Fernandez-Grande

This article proposes a method for estimating the sound absorption coefficient of a material sample by mapping the sound pressure, measured by a microphone array, to a distribution of monopoles along a line in the complex plane.
