房间的脉冲响应包含有关房间大小和形状的抽象信息。声学研究的重点是利用声学建模技术从这些物理特征中获得反射图。然而，通过分析早期反射的脉冲响应、回声幅度、到达时间和混响时间，也可以估计物理结构。本文提出了一种利用带有定向扬声器和声场麦克风的MLS技术获得的定向脉冲响应(DIR)测量的特征来估计房间物理结构的新方法。还展示了4个房间的结果。
Impulse response of a room carries abstract information on the size and shape of that room. Acoustics research has focused on obtaining reflectograms from these physical characteristics using acoustical modelling techniques. However, estimation of the physical structure is also possible by analyzing the impulse responses for early reflections, echo amplitudes, arrival times and reverberation time. This paper proposes a new method to estimate the physical structure of a room using the features of directional impulse response (DIR) measurements obtained by applying the MLS-technique with a directional loudspeaker and a soundfield microphone. The results for 4 rooms were also displayed.
