一、系統概述
1、 System overview
會(huì )議室由于其擴聲功能的特定性較為單一，必須具有良好的語(yǔ)言清晰度，除了需要配備良好的音響設備外，聲學(xué)設計也是非常重要的部分。
Due to the single specificity of its sound reinforcement function, the conference room must have good language clarity. In addition to being equipped with good sound equipment, the acoustic design is also a very important part.
二、設計依據
2、 Design basis
依據各類(lèi)音響標準規范，業(yè)主方提供圖紙和現場(chǎng)勘探數據資料等。
According to various national audio standards and specifications, the owner shall provide drawings and on-site exploration data.
三、設計原則
3、 Design principles
整體設計、靈活、耐用，以高品質(zhì)的音響效果為主，保證語(yǔ)言擴聲的清晰度。
The overall design is advanced, flexible and durable, focusing on high-quality sound effects to ensure the clarity of language reinforcement.
設計時(shí)要考量使用功能和環(huán)境保證均勻覆蓋。
The design shall consider the use function and environment to ensure uniform coverage.
四、功能分析：
4、 Functional analysis:
1、需要良好的語(yǔ)言清晰度，沒(méi)有回音、混響等聲學(xué)缺陷
1. It requires good language clarity without acoustic defects such as echo and reverberation
2、話(huà)筒靈敏度好，說(shuō)話(huà)輕松 不嘯叫；
2. The microphone has good sensitivity and can speak easily without screaming;
3、視頻聲音方向一致性；
3. Video and sound direction consistency;
4、設備簡(jiǎn)單實(shí)用。
4. The equipment is simple and practical.
五、具體方案
5、 Specific scheme
1、設備選型
1. Equipment selection
會(huì )議室一般語(yǔ)言擴聲為主，裝修也比較美觀(guān)，所以一般選用體積小、語(yǔ)言清晰度高的音響。
The conference room is generally dominated by language sound reinforcement, and the decoration is also relatively beautiful, so the sound with small volume and high language definition is generally selected.
話(huà)筒選用手拉手鵝頸話(huà)筒，拾音效果好，容易控制，一鍵開(kāi)關(guān)機。
The microphone is a hand-in-hand gooseneck microphone with good pickup effect and easy control. It can be switched on and off with one key.
2、音頻處理
2. Audio processing
根據使用功能需求，可以只采用音頻處理器，ipad遙控，易操作。
According to the functional requirements, only audio processor and iPad remote control can be used, which is easy to operate.
環(huán)境復雜的會(huì )議室需要音頻處理器選用有反饋抑制功能的音頻處理器，具有視頻會(huì )議則選用回聲功能處理器。
The audio processor with feedback suppression function shall be selected for the conference room with complex environment, and the echo cancellation processor shall be selected for the video conference.
3、設備布置
3. Equipment layout
采用多點(diǎn)擴聲布置，保證均勻覆蓋的有效覆蓋，聲響不會(huì )太大，保證會(huì )議討論語(yǔ)言擴聲清晰度和音樂(lè )還原，不需要太大動(dòng)態(tài)。
The multi-point sound reinforcement arrangement is adopted to ensure the effective coverage of uniform coverage, and the sound will not be too loud, so as to ensure the speech sound reinforcement clarity and music restoration of the meeting discussion, without too much dynamic.
