环境噪声电平检测 这个Device我们在通常的模拟设备中是很难见到的,在矩阵中它要发挥什么样的作用呢?举个例子:我们正在广场或某个博物馆里面循环播放游客须知,此时广播室的工作人员要同时控制很多广播区域,所以很难知道当前各个区域游客的分布情况,只能根据经验来判断送到这个区域的广播音量是大了还是小了。有的时候某区域的游客突然间增多,这时游客就可能会因为周围嘈杂的环境噪声而很难听清楚广播的内容;同样,某个时候游客很少却可能感到广播的声音过于“洪亮”,听起来很不舒服。
Ambient Noise Level Detection This Device We are hard-pressed to find in typical analogue devices. What is the role it plays in the matrix? For example: We are looping through visitor information in the square or in a museum, At this moment, the staff of the broadcasting room should control a lot of broadcasting areas at the same time. Therefore, it is hard to know the current distribution of tourists in each area. Only the experience can tell whether the broadcasting volume sent to this area is big or small. Sometimes there is a sudden increase in tourists in a certain area. Visitors may find it hard to hear the broadcast because of noisy ambient noise. Similarly, at a certain time tourists rarely feel the sound of broadcast is too loud, Sounds uncomfortable.
