When designing a loudspeaker it is essential to perform free-space measurements to see the effects of driver directivity and baffle shape on the important polar response.
当设计一个扬声器时，进行自由场测量以观察喇叭的指向性和障板形状对于极性响应的影响是非常重要的。

Linear distortion - frequency response, polar response, resonance - affects primarily the timbre and clarity of a loudspeaker.
线性失真-频率响应，指向性响应，共振，主要影响音色和清晰度。
