调音系统的噪声来源干两个途径,输入系统的引入噪声,调音系统的内部噪声(包括调音台、功放、EQ(均衡器)及各种音响加工处理设备)等。以下给出产生各种噪声的原因。输入系统噪声: 1.环境噪声:包括午台噪声、广播室噪声、场内噪声、空调噪声、灯光系统噪声等。这类噪声如果处理不当会引起很高的噪声电平。2.空气分子的热运动(布朗运动)引起的噪声,引起的噪声电平较低。3.振动系统内分子热噪声和导体热噪声。杂音电平较高。
Tuning system noise source stem two ways, the introduction of the system noise, mixing system internal noise (including mixer, amplifier, EQ (equalizer) and a variety of audio processing equipment) and so on. The following gives the reason for various kinds of noise. Enter the system noise: 1. Ambient noise: including the afternoon noise, radio room noise, noise floor, air conditioning noise, lighting system noise. Such noise can cause high noise levels if not handled properly. 2. Air molecules due to thermal motion (Brownian motion) caused by noise, causing the noise level is low. 3. Vibrator system molecular thermal noise and conductor thermal noise. Noise level is higher.
