在进行日常的广播电视节目录制过程中,由于某些音频设备的接入、接地不良或者音频线的不正确接法,常常会在录制终端出现一些交流声。这是一种频率在50Hz或者其倍数频率的声音,这种干扰往往让录制的声音不够纯净,严重时使得节目录制无法正常进行。另外,在节目录制过程中可能还会有其它相近频率的辐射干扰。还有一些音源设备的不正确使用造成的人为干扰。本文对分析了各种干扰产生的原因并给出处理方法。
During daily recording of broadcast television programs, some humming often occurs at the recording terminal due to poor access to certain audio equipment, improper grounding, or incorrect connection of the audio cable. This is a type of sound that has a frequency of 50 Hz or a multiple of this. This type of interference tends to make the recorded sound not pure enough, making it hard to record the program properly. In addition, during the program recording may also have other similar frequency of radiation interference. There are also some man-made interference caused by improper use of audio equipment. This article analyzes the causes of various interferences and gives treatment methods.
