3.2 Calibrating Using 85 dB SPL "Standard" Reference
The main purpose of speaker calibration is to ensure that a specific metered
audio level in your DAW or on your mixer equals a predetermined SPL in your
studio environment. Depending upon the method and reference levels used
during calibration, proper calibration can help reduce unwanted noise, minimize
the risk of damage to your studio monitors and to your ears, maximize the
reference capabilities of different speaker types, and ensure you hear the audio
as accurately as possible.
扬声器校准的主要目的是确保在你的DAW或调音台上的特定计量音频电平
等于你的演播室环境中预定的声压级。根据校准过程中使用的方法和参考
电平，正确的校准可以帮助减少不必要的噪音，最大限度地减少对你的演
播室监听器和你的耳朵的损害风险，最大限度地提高不同类型的扬声器的
参考能力，并确保你尽可能准确地听到音频。
When calibrating reference monitors in a studio, the acoustic level or sound
pressure level (SPL) should be measured from the mix position at seated ear
height. There are an assortment of great SPL metering apps on the market for
smartphones, and many are free! You can also find accurate SPL meters at your
favorite local electronics-supply store.
在演播室中校准参考监听器时，应从坐着的耳朵高度的混音位置测量声级
或声压级（SPL）。市场上有各种优秀的智能手机声压级测量应用程序，
而且很多都是免费的！也可以在您喜欢的当地电子用品商店找到准确的声
压级测量仪。
The SPL meter should be held at arm's length, with the microphone pointed at
the center point between the left and right speakers (where your head will be),
angled at 45 degrees to ensure an accurate reading. If your SPL meter is also
your cell phone, make sure your finger or cell phone case isn't covering the mic!
声压级计应与手臂保持一定距离，麦克风对准左右扬声器之间的中心点
（你的头会在那里），角度为45度，以确保读数准确。如果你的声压级计
也是你的手机，请确保你的手指或手机壳没有覆盖住麦克风！
