有没有想过把1.2m再增加一点呢?弄两个架子,放在桌子后面?
之前也了解到,在“60度正三角形”布局的情况下,音箱距离太近:
- 声音会挤在一起。
- 太近的话,会降低音箱的欺骗性,即如果只是距离1米的话,人耳比较容易分辨是音箱还是小提琴;如果距离3、5米的话,音箱回放的声音会感觉更像“真的”。
- 太近的话,最佳听音点的范围会比较小,头部移动或转动,频响会相差比较大
- 如果不是同轴音箱的话,太近的话,高低音单元发声点的间距影响会更明显
- 太近的话,耳朵更容易疲劳

音箱太远,反射声/直达声比例会增大,细节会减少?


Carl Tatz建议”左右近场音箱“理想”间距为67.5英寸、1.715米的说法。说这个距离,可以比较好获得更“自然”的“结像”

Bobby Owsinski,Barry Rudolph好像也都提到过这个“理想”距离
Sonarworks也直接引用了Carl Tatz的这个距离建议

谢谢大佬的建议。摆位方面我也参考了国内外很多教程。音箱有上脚架,高音头跟耳朵同高,并且听歌的时候我 ...

握手握手~~

我现在前后墙是3.5米,(右后角有个1米深的拐角)

听音位距离前墙的距离,我试过1.95,1.9,1.55,1.65米,用REW测、自己试下来还是有一些区别的

我现在距离音箱也是1.2m,下一步准备全拆了,重新布置一下,试试那个1.715米,嘻嘻

关于这事,我原来也问过一圈,想过回复如下,也供了解吧。

Quested的回复是:
So the recommendation is based on monitors with a wide dispersion that is typical of soft dome HF and mid drivers. This is something we have found over years of designing and working with systems that the sounds stage becomes more stable and defined. This when used in the equilateral triangle format we find brings the best experience with wide dispersion monitors.

Genelec R&D的回复是:
Several suggestions like this are floating in the Internet. The principle is that of the equilateral triangle for standard stereo. Equilateral triangle here suggests that the distance from the monitors to the listener is equal to the distance (of the monitor centre lines) between the monitors. This creates the sound stage with correct virtual image locations. In addition, the monitors should be aimed directly at the listening position. The suggestions that the monitors are aimed behind or in the front of the listener are usually suggestions for the products that present the flattest frequency response slightly off-axis. When this is the case, the suggestion of the video makes sense. For each monitor/manufacturer, it is advisable to follow the manufacturer’s recommendations for this. Genelec recommends aiming speakers directly at the listener as this ensures the best flatness of the frequency response and the largest area of flat frequency response around the ideal listening position.

acousticfields的Dennis回复:
There are two sound fields to be concerned about. One is the equilateral triangle set up. Let's call this a near field set up.
A few feet behind that position is more of a far field listening. Both have their pros and cons.


btw,能这样交流,分享学习进步,真的太开心了,哈哈哈

关于1.715m这个距离,之前看到英制单位没什么感觉,换成公制后,那天突然意识到,这个不是和声速343成倍数关系吗?哈哈哈

不过我没找到相关的理论研究paper,做解释分析了,Carl Tatz的表述里,印象好像也只是参考调音台的大小,一般混音棚的空间,以及多年经验,给出的参考建议距离,hoho
