The influence of amplitude and phase errors in microphone arrays on visualization of sound field using acoustical holography

Original language description

This paper describes the results of an investigation of the influence of amplitude and phase errors of a microphone array on the visualization of sound fields. There are several methods for near-field visualization of sound fields. One of the most powerful is Near Field Acoustical Holography (NAH). With this method it is possible to reconstruct a 3D sound pressure field from in-plane measured data. For online visualization of sound fields, use of a microphone array is required. Amplitude and phase errorrs of the microphones used in the microphone array are simulated for different NAH algorithms with a realistic sound source. All simulations are realized in MATLAB.
