通过听力测试评估了两种用于虚拟现实的360°麦克风技术(一阶两用麦克风和等段麦克风阵列)的感知空间属性。此外，还包括一个双耳假人头作为VR音频的基线。被测试的四个属性是：源移位/集合传播、源/集合距离、环境宽度和环境深度。这些测试中使用的刺激包括由人声和乐器组成的单一和多个来源的声音。结果表明，听者能够在四个空间属性中的三个属性上区分出差异。除环境深度外，双耳头部在每个属性上都被评为最高，而FOA被评为最低。
Listening tests were conducted to evaluate perceived spatial attributes of two types of 360° microphone techniques for virtual reality (First Order Ambisonics (FOA) and the Equal Segment Microphone Array (ESMA)). Also a binaural dummy head was included as a baseline for VR audio. The four attributes tested were: source shift/ensemble spread, source/ensemble distance, environmental width and environmental depth. The stimuli used in these tests included single and multisource sounds consisting of both human voice and instruments. The results indicate that listeners can distinguish differences in three of the four spatial attributes. The binaural head was rated the highest for each attribute and FOA was rated the least except for in environmental depth.
