1、 Overall scheme design concept of conference room

會議室/課室內(nèi)布局應(yīng)大氣而樸素，能真實地體現(xiàn)當場人物和大會自然環(huán)境，使與會人員有現(xiàn)場感、一體感以做到視覺效果、語言溝通交流的顯著成績。遠程控制會議室/課室中傳輸?shù)膱D象包含人物、景色、數(shù)據(jù)圖表、文本等，應(yīng)清晰可辨。遠程控制會議室/課室內(nèi)要維持事項的溫度、環(huán)境濕度、室內(nèi)通風(fēng)度，使與會人員覺得舒服、當然。

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、會議室合理布局規(guī)定

2、 Regulations on reasonable layout of meeting rooms

為了更好地保證多媒體會議系統(tǒng)圖象的收看實際效果和避免顏色對人物拍攝造成的“絢麗”或“返光”實際效果，電視背景墻應(yīng)采用單一勻稱的淺顏色，而多媒體會議系統(tǒng)室其他墻面、餐桌布、毛毯、吊頂天花板等應(yīng)與電視背景墻相符合，電視背景墻不適合應(yīng)用中畫幅。提議桌椅板凳及墻面采用淺卡其色或淺青藍色。桌椅不適合采用布藝沙發(fā)式，也不適合采用高椅背，防止遮擋后邊的與會人員。

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.

影響畫質(zhì)的一大要素，是主會場四周的景色和顏色，及其桌椅板凳的色彩。一般不宜“白”、“灰黑色”這類的色彩，這二種顏色對身體將造成“返光”及“奪光”的欠佳效用。因此 不管墻面四周、桌椅板凳均采用淺色系色彩比較適合，如墻面四周淺黃色，淡綠，桌椅板凳淺咖色等，南方地區(qū)宜用冷色調(diào)，北方地區(qū)宜用暖色調(diào)。對拍攝情況(被攝人物身后的墻)不適合掛有山水國畫等景色，不然將提升拍攝目標的數(shù)據(jù)量，不利多媒體會議系統(tǒng)圖象品質(zhì)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.

三、會議室聲學(xué)材料規(guī)定

3、 Regulations on acoustic materials for meeting rooms

為確保多媒體會議系統(tǒng)聲音絕緣層與吸音實際效果，會議系統(tǒng)的房間內(nèi)鋪有毛毯、吊頂天花板、四周墻面內(nèi)都配有隔音毯，窗子應(yīng)采用雙層中空玻璃，進外出應(yīng)考慮到隔音降噪設(shè)備。另外吸音不必過多，防止聲音發(fā)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.

依據(jù)聲學(xué)技術(shù)規(guī)定，一定容量的會議室有一定混響時間的規(guī)定。一般來說，混音的時間過短，則聲音枯燥乏味發(fā)澀;混響時間太長，聲音又混淆不清。因而，不一樣的會議室都是有其的混響時間，如混響時間適合則能清理新聞發(fā)言人的聲音，遮蓋噪音，提升大會的實際效果。音箱的布局應(yīng)以會議室獲得勻稱的音場，且能避免 聲音傳回。會議音響系統(tǒng)的功率放大電路應(yīng)采用多個小容積功率放大電路集中化設(shè)定在同一主會場的方法，用有效的走線和轉(zhuǎn)換系統(tǒng)軟件，確保會議室在毀壞一臺功放機時，不導(dǎo)致主會場聲音終斷。聲音數(shù)據(jù)信號鍵入功率放大電路以前，應(yīng)采用均衡器和反饋抑制器開展解決,以提升 聲音數(shù)據(jù)信號的品質(zhì)。

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.
