在本文中，我们描述了一种方法，用于重建的温度分布在一个矩形空间使用少量的声学换能器。通过利用壁面反射波减少了换能器的数量。通过在一个墙面上安装两个扬声器和在对立面上安装两个麦克风，实现了五个分区的空间分辨率。此外，分辨率中的分区模式根据需要紧密分布的情况进行切换，而不会使声换能器移位。在本研究中，仿真和实验部署，以测试这种方法的充分性。通过数值模拟实现了在分辨率中切换分区模式的可能性，并将结果与在真实的空间中测量的温度分布进行了比较。实验是在真实的空间中进行的，该空间具有显著的温度分布和加热空气。由测量结果重建的温度分布与热电偶测量的温度分布相似。
In this paper, we describe a method for reconstruction of the temperature distribution in a rectangular space using a small number of acoustic transducers. The transducers were decreased in number by utilizing the reflected waves from wall surfaces. Spatial resolution of five divisions has been realized by installing only two speakers for a wall surface and two microphones for the counter wall surface. Additionally, the partition pattern in the resolution was switched depending on the situation that required close distribution without displacing the acoustic transducers. In this study, simulation and experiment were deployed for testing the adequacy of this method. The possibility of switching the partition pattern in the resolution was realized by numerical simulation and the result was compared to temperature distribution that was measured in real space. The experiment was performed in real space which has a significant temperature distribution with heated air. The temperature distribution reconstructed from the measurement results was similar to the distribution measured by thermocouples.
