音響效果可分為有音源音響效果與無音源音響效果兩大類。有音源音響效果也可稱作“現實性效果”。這類音響的特點在于無論是在舞臺上出現或是從舞臺外傳來，都有其現實的可靠根據和來源。無音源音響效果又可稱為“非現實性效果”。
Sound effects can be divided into two categories: sound effects with sound source and sound effects without sound source. Sound effect with sound source can also be called "realistic effect". The characteristic of this kind of sound is that whether it appears on the stage or comes from outside the stage, it has its realistic and reliable basis and source. Sound effect without sound source can also be called "non realistic effect".
這類音響不需要有實際的來源作為根據，而是為了側重描繪人物的心理狀態、渲染特殊氣氛與情調。另外，有音源音響效果同無音源音響效果的有機結合，還可派生出混合性的音響效果。它既有現實生活的可靠來源，又有非現實的因素，兩者相互轉換，交替展示，用以豐富音響效果的表現情趣和手法。
This kind of sound does not need the actual source as the basis, but focuses on the description of the psychological state of the characters, and plays up the special atmosphere and sentiment. In addition, the organic combination of sound effects with and without sound sources can also derive mixed sound effects. It has both reliable sources of real life and non realistic factors, which are transformed and displayed alternately to enrich the expressive interest and technique of sound effects.
多功能報告廳兼具的功能較多，常見的就是作為開會使用的多功能會議和匯報演講這兩種用途較為常見。一般來說，多功能報告廳面積大概在300到500之間，容納人數大概在200人到300人。
The multi-functional lecture hall has many functions, and the common ones are multi-functional meetings and reports. Generally speaking, the multi-function lecture hall covers an area of 300 square meters to 500 square meters, and can accommodate 200 to 300 people.
多功能報告廳對于聲場的設計比較嚴格，要兼具會場前、中、后的聲壓，而且，音頻質量也要求非常高。
The multi-functional lecture hall is strictly designed for the sound field, which should have both the sound pressure before, during and after the meeting. In addition, the audio quality is also required to be very high.
多功能報告廳作用主要作為滿足日常會議語音擴聲、學術報告、學習培訓、演講等功能。
The multi-function lecture hall is mainly used to meet the needs of daily conference voice reinforcement, academic reports, learning and training, speeches and other functions.
通過對會議室的布局環境分析，對
報告廳音響設備進行合理的布置與連接，并安裝以上的音響設備，可以使聲源和音響系統末端——音箱同處于一個聲場區域內，使觀眾能感受到聲源的真實存在，達到高保真重放的擴聲要求。音響以自然聲為主，要求擴散性良好，聲場分布均勻，響度合適，自然度好等要求。
Through the analysis of the layout environment of the conference room, the sound equipment in the lecture hall shall be reasonably arranged and connected, and the above sound equipment shall be installed, so that the sound source and the end of the sound system speaker can be located in the same sound field area, so that the audience can feel the real existence of the sound source, and meet the sound reinforcement requirements of high fidelity reproduction. The sound is mainly natural sound, which requires good diffusion, even distribution of sound field, appropriate loudness, good naturalness, etc.
How to select the sound effect to ensure the audio reinforcement in the lecture hall? The above is the question content for you. Come to our website if you need http://www.zkvd.cn Feel free to consult!
