一、會(huì )議室總體方案設計觀(guān)念
1、 Overall scheme design concept of conference room
會(huì )議室/課室內布局應大氣而樸素,能真實(shí)地體現當場(chǎng)人物和大會(huì )自然環(huán)境,使與會(huì )人員有現場(chǎng)感、一體感以做到視覺(jué)效果、語(yǔ)言溝通交流的顯著(zhù)成績(jì)。遠程控制會(huì )議室/課室中傳輸的圖象包含人物、景色、數據圖表、文本等,應清晰可辨。遠程控制會(huì )議室/課室內要維持事項的溫度、環(huán)境濕度、室內通風(fēng)度,使與會(huì )人員覺(jué)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(huì )議室合理布局規定
2、 Regulations on reasonable layout of meeting rooms
為了更好地保證多媒體會(huì )議系統圖象的收看實(shí)際效果和避免顏色對人物拍攝造成的“絢麗”或“返光”實(shí)際效果,電視背景墻應采用單一勻稱(chēng)的淺顏色,而多媒體會(huì )議系統室其他墻面、餐桌布、毛毯、吊頂天花板等應與電視背景墻相符合,電視背景墻不適合應用中畫(huà)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(huì )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(huà)質(zhì)的一大要素,是主會(huì )場(chǎng)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(lèi)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,南方地區宜用冷色調,北方地區宜用暖色調。對拍攝情況(被攝人物身后的墻)不適合掛有山水國畫(huà)等景色,不然將提升拍攝目標的數據量,不利多媒體會(huì )議系統圖象品質(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(huì )議室聲學(xué)材料規定
3、 Regulations on acoustic materials for meeting rooms
為確保多媒體會(huì )議系統聲音絕緣層與吸音實(shí)際效果,會(huì )議系統的房間內鋪有毛毯、吊頂天花板、四周墻面內都配有隔音毯,窗子應采用雙層中空玻璃,進(jìn)外出應考慮到隔音降噪設備。另外吸音不必過(guò)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.
依據聲學(xué)技術(shù)規定,一定容量的會(huì )議室有一定混響時(shí)間的規定。一般來(lái)說(shuō),混音的時(shí)間過(guò)短,則聲音枯燥乏味發(fā)澀;混響時(shí)間太長(cháng),聲音又混淆不清。因而,不一樣的會(huì )議室都是有其的混響時(shí)間,如混響時(shí)間適合則能清理新聞發(fā)言人的聲音,遮蓋噪音,提升大會(huì )的實(shí)際效果。音箱的布局應以會(huì )議室獲得勻稱(chēng)的音場(chǎng),且能避免 聲音傳回。會(huì )議音響系統的功率放大電路應采用多個(gè)小容積功率放大電路集中化設定在同一主會(huì )場(chǎng)的方法,用有效的走線(xiàn)和轉換系統軟件,確保會(huì )議室在毀壞一臺功放機時(shí),不導致主會(huì )場(chǎng)聲音終斷。聲音數據信號鍵入功率放大電路以前,應采用均衡器和反饋抑制器開(kāi)展解決,以提升 聲音數據信號的品質(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.
