A method is presented that makes it possible to reconstruct an arbitrary sound field based on
measurements with a spherical microphone array. The proposed method (spherical …

A method is proposed to estimate the surface impedance of a large absorptive panel from
free-field measurements with a spherical microphone array. The method relies on the …

The equivalent source method (ESM)-based sound field separation technique has been
successfully introduced into near-field acoustic holography as a preprocessing tool to …

In environmental acoustics and in room acoustics, many surfaces exhibit extended-reaction
(ER) behavior, ie, their surface impedance varies with the angle of the incident sound wave …

In practical situations, vibrating objects are usually located above a reflecting plane instead
of exposing to a free field. The conventional nearfield acoustic holography (NAH) sometimes …

This thesis is concerned with the problem of noise source identification in closed spaces.
The main motivation was to propose a technique which allows to locate and quantify noise …

In noisy environments, the acoustic wave is complicated and consists of the radiated wave,
the incident wave, as well as its scattering wave. Double-layered pressure measurement is …

This paper investigates the efficiency of a field separation method for the identification of
sound sources in small and non-anechoic spaces. When performing measurements in such …

Absorption coefficients are mostly measured in reverberation rooms or with impedance
tubes. Since these methods are only suitable for measuring the random incidence and the …
