Sound source localization accuracy of ambisonic microphone in anechoic conditions
نویسنده
چکیده
The paper presents results of determination of sound source localization based on signals measured by first-order ambisonic microphone. The experiment consisted in recording the test signals with the 3D microphone positioned in the axis of the turntable in the anechoic chamber. The spherical coordinates of the sound intensity vector were calculated and compared to actual values resulting from the geometry of the system. Accuracy of the localization of the sound source depending on the frequencies, the time constant and the parameters of the signal recording was presented. The obtained results show the effectiveness of the sound source localization using first order ambisonic microphone in laboratory conditions.

Comparison of patch acoustic holography methods for confined space
Localization and characterization of noise and vibration sources through measurement of sound fields radiated from vibrating structures plays an important role in vibration diagnostics. Sound pressure field measured in closed distance to the source with a microphone array is then inversely processed with the suitable near-field acoustic holography method to obtain the estimation of sound field ...
متن کاملObjective Localisation Measures in Ambisonic Surround- sound
When designing sound spatialisation systems, localisation accuracy is of great importance, i.e. how well the reproduction of the sound source corresponds to the original recording particularly with respect to source positioning. Ambisonic surround-sound is one such spatialisation system. In this work the two major psychoacoustic mechanisms Interaural Time Difference (ITD) and Interaural Level D...

The accurate recording and reproduction of real 3D sound environments is still a challenging task. In this paper, the two most established 3D microphones are evaluated: the Soundfield SPS200 and MH Acoustics’ Eigenmike EM32, according to 1 and 4 order Ambisonics. They are compared to virtual encoded sound sources of the same orders in a localization test. For the reproduction, an Ambisonics sys...

In real environments, the presence of ambient noise and room reverberations seriously degrades the accuracy in sound source localization. In addition, conventional sound source localization methods cannot localize multiple sound sources accurately in real noisy environments. This paper proposes a new method of multiple sound source localization using a distributed microphone system that is a re...
