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 errors 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.
