摘要
通过对声柱指向性的分析,结合高音波导柱面波的形成,得出了线阵列应该有低音和高音两个不同指向性的结论,这与传统形式音箱的技术指标中只有高音指向性是有区别的。指出目前人们对线阵列指向性认识的误区,进而提出在进行线阵列声场调试过程中应该注意的问题。
The conclusion of two different directivity including bass and treble which line array should comprise are given through the analysis of sound column point combined with the formation of treble waveguide cylindrical wave. It＇s different from technical index of traditional baffle box which only has treble directivity. The recognition misunderstanding of line array point is proposed. The problem during line array commission process that should pay attention to is proposed.
