Based on the higher order Ambisonics theory, a loudspeaker-based room auralization system was implemented in this paper in combination with a room acoustics computer model. In the decoding part of the Ambisonics technique, the generally used mode-matching decoding method requires a uniformly arranged loudspeaker array, which sometimes cannot be satisfied. A recently proposed method, the matching projection decoding method, which can solve this problem, was introduced in the room auralization system to realize reproduction of room re-verberation with non-uniform loudspeaker arrays. Moreover, the performance of the matching projection method was evaluated objectively through room impulse response reconstruction analysis. Besides, the room auralization system is validated through subjective experiments.
