The purpose of this study is to train the reconstructed sound waves, which is obtained from recording holograms via digital holography, and reduce the noise from this sound wave without using noise filtering techniques. The noise reduction is achieved by approximating the reconstructed sound wave trained by YSA to the actaul recording sound wave. A network topology is created for training and the system was tested. The performance of the system is given by showing how closely the sound wave trained by YSA approaches the actual sound wave.
