Impedance estimation of a finite absorber based on spherical array measurements
TL;DR: In this article, a method to characterize the surface impedance of materials is presented, based on pressure measurements with a spherical microphone array, which are used to reconstruct the sound pressure and particle velocity on the sample's surface, from which the material impedance is inferred.
Scalable microphone array system optimized for streaming inverse acoustics
TL;DR: The aim is to develop a compact and low-cost acquisition system that is expandable to hundreds of channels and enables inverse acoustics as a streaming application.

Visualization of Linear Operations in the Spherical Harmonics Domain
Maximilian Kentgens,Peter Jax +1 more
TL;DR: In this paper, the authors identify different key properties of linear operations on coefficients in the spherical harmonics transform domain and propose a method for their visualization, which gives rise to a comprehensive interpretation of the behavior of a system.
