Ambisonic impulse responses (also known as the Spatial Impulse Responses) are getting more and more popular in many applications of room acoustics. Measuring, modeling, synthesizing, or simulating acoustics of interiors with emphasize on their spatial features are the examples. The present article shows a methodology of room acoustics auralization assessment using the ambisonics technology. A case study is shown for room acoustics capturing (measuring the Spatial Impulse Response) and reproducing with the use of a multi-channel sound system. An discussion and considerations about fidelity of such reconstruction is provided. Furthermore, a quantitative measure for the auralization quality is proposed. Also on-site experiments are described and their results presented to illustrate the theoretical considerations and outline options for future work. Obtained results show that most of the proposed quality factors meet the assumptions. After possible future modifications and additional research, the proposed methods could be used in evaluation of room acoustic auralization.
