单个全向声源可能是音频圣盘吗?
Is perhaps a single omnidirectional source the Holy Grail of audio?
但是,如果目标是精确的重放声音的话,一个扬声器必须是声学上的点声源(单极点,全向响应),或者是一个声学上小的双向源(偶极)。
But if the goal is to reproduce sounds accurately, then a speaker must be either an acoustic point source (monopole, omni-directional) or an acoustically small bi-directional source (dipole).
