【最值得投入的音响器材居然是她们?】针对人类设计的音响

如果知道音箱决定整个系统80%以上的失真,
就不难理解为什么资深发烧友会将一半以上预算投到音箱上了。
尤其年纪大的,几乎都接触过一种音箱,
因为这种类型音箱,更容易得到接近真实的人声(嘴形),乐器(体积大小)和舞台感的真实感!

作为资深音响人士,
通常已不再是比谁更大更响,一顿吃了几两肉。

他们更在乎的是肉的品质,新鲜度与原味几何。
甚至色泽,摆盘。所谓色香味俱全。

也就是他们嘴里经常看到的系统评判准则,
人声(嘴形大小),乐器(体积大小)和舞台感。也有一种叫法,三轴试听法则。

其实这些都是涉及一种失真:Phase 相位失真
看到这个词就头痛,因为搞不清楚,所以脑阔疼。
(并不是每个人都知道金嗓子Accuphase名字就是“精确相位”的意思)
简单来说,就是高低频的音乐信号,经过各种元器件后,
先后抵达目的地--到耳朵的“时间先后的误差”大小。
有位哲学家说得好:人们只会去算自己算得清的账。
对于大多数发烧友,会查看音箱的频响曲线,看”平直“与否。
但其实更重要的,远非只是频响曲线,
其实可以从分频点的设置上看出,设计师对“相位”的重视度。
那音箱分频点在什么范围的音箱,相位失真最小?
如何从音箱的分频点判断设计师对“嘴型大小”和”乐器大小“的重视度?

这是著名的人耳等响度曲线红色是2003年国际测量结果。
可以看到,在80dB的录音室标准下,
2000hz-5000hz,是人耳,人类耳朵最敏感的区域。
那这对高保真音箱的重播,意味着什么呢?

这是一张同样重要,但更专业的,关于音箱分频点的图。
其中可以看到,在分配点左右的范围,两个单元会有一段范围的重合,
比如取2000hz(F0),意味着从(fo/2)1000-2000(fo),以及(fo)2000-4000hz(2fo),都是2同单元的重叠。
这对相位失真,是不言而喻的。
所以,为了避免2000-5000hz的相位失真,也就是由同一只喇叭单于负责,
分频点可取的范围应该在低于1000hz,且高于10.000hz
这样,才可以有效避免由于多只不同喇叭的重叠而造成的失真。
