The ever-improving immersive sound regeneration techniques have created an entire branch of novel audio signal processing techniques and 3D audio playback systems, each implemented for a specific purpose. The wide area of application desires specific features requiring a suitable recreation sound field method. The limitations of these approaches motivated the scientists to continuously establish new algorithms to improve the sound quality. 3D sound generation using an array of small speakers is a method which was developed recently. The Pressure Matching Method (PMM) has been developed to efficiently recreate 3D sound with a speaker array. A new mathematical approach which enhances the effectiveness of PMM was represented by the authors in [1]. In this paper, the results of the physical measurements conducted to make an assessment of the method are demonstrated. The outcome shows that in comparison with the traditional PMM with Tikhonov regularization technique, the eigen decomposition pseudoinverse technique improves the PMM efficiency through giving rise to a greater segregation of the received sound at the listener’s ears and consequently, a more immersive 3D sound field around the listener’s head.
