 众所周知,人体自然发出的声音的传播范围是非常有限的,尤其是在诺大的会议厅或者体育场进行开会或者演讲时,人体发出的自然声音是不能满足大型场地的需要的,所以这个时候就要用到会议音响系统,这种音响有着非常好的扩音功能,但是也往往会出现这样那样的干扰性问题,接下来就和大家简单介绍几种常见的干扰问题。

    第一,电源的干扰,要是电源的接地线不好,设备之间各种线路接触不良,就会产生静电干扰从而导致音响输出的各种音频信号受到很大的干扰,出现噪音。

    第二,如果两个音响或者多个音响之间靠的非常近,那么它们彼此之间就会受到很大的干扰,甚至很会造成其中某些音响不能发声,这种干扰是最常见的。

 

    第三,灯光的干扰,大家都知道电流可以产生巨大的磁场,所以如果音响靠灯光太近就会导致灯光电线产生的磁场影响到音响的扩音效果。
