不同的會(huì )議類(lèi)型和拾音環(huán)境對混響和延時(shí)的懇求不同，因此要根據聲學(xué)特性，調整混響和延時(shí)的參數。那么
會(huì )議音響的使用出現混響延時(shí)不當現象怎么回事呢？
Different conference types and pickup environments have different demands on reverberation and delay. Therefore, parameters of reverberation and delay should be adjusted according to acoustic characteristics. What about the improper reverberation delay in the use of conference audio?
①會(huì )場(chǎng)的大小影響聲場(chǎng)混響中反射的時(shí)間和聽(tīng)覺(jué)上的時(shí)間感。
① The size of the venue affects the time of reflection in the sound field reverberation and the sense of time in hearing.
②混響時(shí)間反映聲音從聲源擴散經(jīng)周?chē)蘸头瓷涞倪^(guò)程，混響時(shí)間視會(huì )場(chǎng)的大小而定，空間越大，混響時(shí)間也越大。要經(jīng)過(guò)音頻處置設備補償和修飾某些聲音的缺陷，但調整不當，就會(huì )適得其反。若混響時(shí)間過(guò)長(cháng)，聲音就有“混濁”感，因此要別離理論，合理參與混響效果，以增強聲音的縱深感。延時(shí)處置也是如此。
② The reverberation time reflects the process of sound diffusion from the sound source to the surrounding absorption and reflection. The reverberation time depends on the size of the venue. The larger the space, the greater the reverberation time. It is necessary to compensate and modify some sound defects through audio processing equipment, but improper adjustment will be counterproductive. If the reverberation time is too long, the sound will have a sense of "turbidity". Therefore, we should leave the theory behind and reasonably participate in the reverberation effect to enhance the depth of the sound. The same is true for delayed disposal.
③混響的頻率特性反映在不同頻率下聲音的混響效果和音質(zhì)。要熟習混響的頻率特性，調整好麥克風(fēng)拾取直達聲與反射聲的比例，增加聲音的真實(shí)感和明晰度。
③ The frequency characteristics of reverberation reflect the reverberation effect and sound quality of sound at different frequencies. Be familiar with the frequency characteristics of reverberation, adjust the proportion of direct sound and reflected sound picked up by the microphone, and increase the realism and clarity of the sound.
④聲擴散是反映會(huì )場(chǎng)聲學(xué)特性的參數，要合理設置麥克風(fēng)，補償會(huì )場(chǎng)聲擴散條件的缺陷，同時(shí)要避開(kāi)具有哆嗦回聲區域和強反射的方向。
④ Sound diffusion is a parameter reflecting the acoustic characteristics of the meeting place. Microphones should be set reasonably to compensate for the defects of sound diffusion conditions in the meeting place, and at the same time, areas with shivering echo and strong reflection should be avoided.
