The perceptual differences between virtual reality and its reproduction with different simulated multichannel microphone techniques were measured using listening tests. The virtual reality was generated using image-source method, and 16 loudspeakers in a 3-D arrangement in an anechoic chamber. Two spaced, and two coincident microphone techniques were tested, namely Fukada Tree, Decca Tree, 1st order Ambisonics and 2nd order Ambisonics. The spaced techniques utilized 5.0 setup, and Ambisonics techniques utilized the quadraphonic setup. The perceptual difference was measured with ITU impairment scale.
