Mic Position and Room Analysis
麦克风位置和房间分析
Improper mic placement when analyzing a sound system
can result in the system appearing to have problems that
don't actually exist. Below is a quick reference for proper
mic placement.
在分析音响系统时，不正确的麦克风放置会导致系统
看起来有问题，但实际上并不存在。下面是正确放置
麦克风的快速参考。
Primary Mic Position
主要麦克风位置
This is the main reference point for a speaker and can be
used as a single, "representative" position. Your goal in
setting the primary mic position is to find a point that
puts the microphone inthe center (on axis) of a speaker's
throw, within the listening area. In other words, you
want to put the microphone smack dab in the middle of
where your speaker sounds its best.
这是一个扬声器的主要参考点，可以作为一个单一的
"代表 "位置。设置主麦克风位置的目标是找到一个点，
将麦克风放在扬声器投射的中心（轴上），在聆听区
域内。换句话说，你要把麦克风放在扬声器声音最好
的地方的中间。
Secondary Mic Position
次要麦克风位置
Secondary mic positions provide your system analysis
with more information to get a more "three-dimensional"
view of your system. These can be on- or off-axis
measurements of a speaker within the listening area.
Avoid using locations outside the core coverage area of
your system, or on the edges.With any mic position,
avoid creating position-dependent anomalies.
辅助麦克风位置为你的系统分析提供了更多的信息，
以获得你的系统的更多 "三维 "视图。这些可以是聆听
区域内扬声器的轴上或轴外测量。避免使用系统核心
覆盖区域以外的位置，或者边缘的位置。对于任何麦
克风的位置，都要避免产生与位置有关的异常情况。
Ground Bounce
地面反射
Ground reflections, or "ground bounce," become an issue
when a speaker is flown and angled down.
The proper mic position, in this case, will also catch the
reflection of the signal off the floor.
地面反射，或称 "地面反弹"，当一个扬声器吊起来并
向下倾斜时就成了一个问题。
在这种情况下，合理的麦克风位置也会捕捉到地面上
的信号反射。
（Reflection arrive ~4ms late. 反射到达有4毫秒延迟）
In this case, you can choose from three options:
在这种情况下，你可以从三个选项中选择：
•Block the reflection with a baffle.
-用挡板挡住反射。
•Do a ground-plane measurement.
-做一个地平面的测量
•Do a multi-point measurement to randomize the effect
of the floor bounce.
-做一个多点测量，使地板反弹的影响随机化。
