许多人有一个误区,认为传声器只能拾取到它正前方的声音,就像摄像头只能拍到位于镜头前方的图像那样,其实要真是这样那倒还好了,但事实是我们只能取得近似的效果,同时我们还要顾及到实际录音时其他方面的问题。传声器的指向性图1是传声器的极坐标图,它们反映了声音的角度和输出信号的比值。输出由入射角的曲线弧度来表示。 Many people have a misunderstanding that the microphone can only pick it right in front of the sound, just as the camera can shoot the image in front of the camera, in fact, it really is so down, but the fact that we can only get approximate At the same time we have to take into account the other aspects of the actual recording. Microphone Directivity Figure 1 shows the polar plot of the microphones, which shows the ratio of the angle of the sound to the output signal. The output is represented by the curve radian of the angle of incidence.
