Emission Test Method for Source Stirred Reverberation Chambers With Scalar Measurements
This paper describes a novel method to reconstruct the radiated emission of a device under test placed in a reverberation chamber equipped with multiple monopole source stirring technique. The method is based on the measurement of the normal component of

Angle-Dependent Absorption of Sound on Porous Materials
Sound-absorbing materials are usually measured in a reverberation chamber (diffuse field condition) or in an impedance tube (normal sound incidence). In this paper, we show how angle-dependent absorption coefficients could be measured in a factory-type ...

Auditory environmental context affects visual distance perception
In this article, we show that visual distance perception (VDP) is influenced by the auditory environmental context through reverberation-related cues.

Analysis of Plane Waves Spectra in a Weakly-Disturbed Flat Reverberation Chamber by Information Theory Criteria [PDF]
This work aims to present the impact of disturbing the stationary modes in a rectangular-shaped reverberation chamber by small-dimensioned stirrers. The study focuses on plane wave’s modeling of the electric field inside a flat cavity using information ...

Correlation and Capacity Calculations with Reference Antennas in an Isotropic Environment
A reverberation chamber is a convenient tool for over-the-air testing of MIMO devices in isotropic environments. Isotropy is typically achieved in the chamber through the use of a mode stirrer and a turntable on which the device under test (DUT) rides ...
