Spherical antenna array (SAA) has become highly attractive where hemispherical scan
coverage is required as it can provide uniform directivity in all the scan directions. Various …

Spherical harmonic decomposition facilitates decomposing the sound pressure at different
microphones into independent functions of frequency, azimuth and elevation of the source …

This paper presents an experimental and comparative study of several spherical
microphone array eigenbeam (EB) processing techniques for localization of early reflections …

In this article, we present a novel localization method for multiple sources in indoor
environments. Our approach can estimate different propagation paths, including the …

The knowledge of parameters characterizing an acoustic environment, such as the
geometric information about a room, can be used to enhance the performance of several …

In this paper, we propose novel deterministic and Bayesian methods to identify the
directions-of-arrival (DOAs) of coherent multipath signals assuming that a very few number …

Room impulse responses (RIRs) have been widely used for room acoustics analysis. One of
the major objectives in room acoustics analysis is characterizing the directions of arrival …

Large-scale Room Impulse Response (RIR) measurements are required to accurately
determine a room's acoustic response to different source-listener configurations. RIR …

Spherical microphone arrays provide a powerful tool for examining source localization and
direction of arrival (DOA) estimation in the spherical harmonic domain. In previous work, we …

A soundfield image is a data structure that efficiently encodes and represents the wave field
as captured by a microphone array. Its representation is based on the directional …
