一、会议室总体方案设计观念
1、 Overall scheme design concept of conference room
会议室/课室内布局应大气而朴素，能真实地体现当场人物和大会自然环境，使与会人员有现场感、一体感以做到视觉效果、语言沟通交流的显着成绩。远程控制会议室/课室中传输的图象包含人物、景色、数据图表、文本等，应清晰可辨。远程控制会议室/课室内要维持事项的温度、环境湿度、室内通风度，使与会人员觉得舒服、当然。
The layout of the conference room / classroom shall be atmospheric and simple, which can truly reflect the on-site people and the natural environment of the conference, so that the participants have a sense of scene and integration, so as to achieve remarkable results in visual effect and language communication. The images transmitted in the remote control conference room / classroom include characters, scenery, data charts, texts, etc., which shall be clear and legible. The temperature, ambient humidity and indoor ventilation in the remote control conference room / classroom shall be maintained to make the participants feel comfortable and natural.
二、会议室合理布局规定
2、 Regulations on reasonable layout of meeting rooms
为了更好地保证多媒体会议系统图象的收看实际效果和避免颜色对人物拍摄造成的&濒诲辩耻辞;绚丽&谤诲辩耻辞;或&濒诲辩耻辞;返光&谤诲辩耻辞;实际效果，电视背景墙应采用单一匀称的浅颜色，而多媒体会议系统室其他墙面、餐桌布、毛毯、吊顶天花板等应与电视背景墙相符合，电视背景墙不适合应用中画幅。提议桌椅板凳及墙面采用浅卡其色或浅青蓝色。桌椅不适合采用布艺沙发式，也不适合采用高椅背，防止遮挡后边的与会人员。
In order to better ensure the actual viewing effect of multimedia conference system images and avoid the "gorgeous" or "back light" actual effect caused by color on character shooting, the TV background wall shall adopt a single and symmetrical light color, and other walls, dining table cloth, blanket, ceiling, etc. of multimedia conference system room shall be consistent with the TV background wall, The TV background wall is not suitable for the picture frame in the application. It is proposed to use light khaki or light cyan for tables, chairs, benches and walls. Tables and chairs are not suitable for cloth sofa type, nor are they suitable for high chair back to prevent covering the participants behind.
影响画质的一大要素，是主会场四周的景色和颜色，及其桌椅板凳的色彩。一般不宜“白”、“灰黑色”这类的色彩，这二种颜色对身体将造成“返光”及“夺光”的欠佳效用。因此 不管墙面四周、桌椅板凳均采用浅色系色彩比较适合，如墙面四周浅黄色，淡绿，桌椅板凳浅咖色等，南方地区宜用冷色调，北方地区宜用暖色调。对拍摄情况(被摄人物身后的墙)不适合挂有山水国画等景色，不然将提升拍摄目标的数据量，不利多媒体会议系统图象品质的提升 。
A major factor affecting the image quality is the scenery and color around the main venue, as well as the color of tables, chairs and benches. Generally, colors such as "white" and "gray black" are not suitable. These two colors will cause poor effects of "returning light" and "seizing light" on the body. Therefore, no matter around the wall, tables, chairs and benches, light colors are more suitable, such as light yellow, light green around the wall, light coffee color of tables, chairs and benches, cold colors should be used in the South and warm colors should be used in the north. For the shooting situation (the wall behind the subject) it is not suitable to hang landscapes, traditional Chinese paintings and other scenery, otherwise the amount of data of the shooting target will be increased, which is not conducive to the improvement of the image quality of the multimedia conference system.
叁、会议室声学材料规定
3、 Regulations on acoustic materials for meeting rooms
为确保多媒体会议系统声音绝缘层与吸音实际效果，会议系统的房间内铺有毛毯、吊顶天花板、四周墙面内都配有隔音毯，窗子应采用双层中空玻璃，进外出应考虑到隔音降噪设备。另外吸音不必过多，防止声音发干。
In order to ensure the actual effect of sound insulation layer and sound absorption of the multimedia conference system, the room of the conference system is paved with blankets, ceiling, and sound insulation blankets are equipped in the surrounding walls. The windows shall adopt double-layer insulating glass, and the sound insulation and noise reduction equipment shall be considered when entering and leaving. In addition, there is no need to absorb too much to prevent the sound from drying.
依据声学技术规定，一定容量的会议室有一定混响时间的规定。一般来说，混音的時间过短，则声音枯燥乏味发涩;混响時间太长，声音又混淆不清。因而，不一样的会议室都是有其的混响时间，如混响时间适合则能清理新闻发言人的声音，遮盖噪音，提升大会的实际效果。音箱的布局应以会议室获得匀称的音场，且能避免 声音传回。会议音响系统的功率放大电路应采用多个小容积功率放大电路集中化设定在同一主会场的方法，用有效的走线和转换系统软件，确保会议室在毁坏一台功放机时，不导致主会场声音终断。声音数据信号键入功率放大电路以前，应采用均衡器和反馈抑制器开展解决,以提升 声音数据信号的品质。
According to the acoustic technical regulations, the conference room with a certain capacity has a certain reverberation time. Generally speaking, if the mixing time is too short, the sound will be dull and astringent; The reverberation time is too long and the sound is confused. Therefore, different conference rooms have the best reverberation time. If the reverberation time is appropriate, it can clean up the voice of the press spokesman, cover the noise and improve the actual effect of the conference. The layout of the speaker shall obtain a symmetrical sound field in the conference room and avoid sound transmission back. The power amplification circuit of the conference sound system shall adopt the method of centralized setting of multiple small volume power amplification circuits in the same main venue, and use effective wiring and conversion system software to ensure that the sound of the main venue will not be interrupted when a power amplifier is destroyed in the conference room. Before the sound data signal is input into the power amplification circuit, equalizer and feedback suppressor shall be used to improve the quality of sound data signal.
