Inorder to study the acoustic and vibratory behavior of a sonorous source by means of images reconstructed with the technique Near-Field Acoustic Holography (NAH) from experimental measurements of sound pressure, it is necessary to filter the signal of entrance in the wave number space to obtain a good resolution of the reconstructed image. The components of greater number of wave related to the distortion of the information, therefore it is natural to hope that the best results will be obtained when the components of greater number of wave are eliminated, that is to say, filtering. Nevertheless, the filter reduces the resolution in the prediction plane. This means that the resolution in the prediction plane is different from the resolutin in the hologram plane. in this work it is carried out a study of the parameters of the Wiener filterused in the reconstruction of the acoustic parameters of a sonorous source by means of NAH. The value of the parameters used in this filter are optimized with the objective of obtaining images with good qualityof reconstruction and location of sonorous sources, as well as values similar to the obtained ones with the conventional techniques.
