不同的會議類型和拾音環(huán)境對混響和延時的懇求不同，因此要根據(jù)聲學(xué)特性，調(diào)整混響和延時的參數(shù)。那么
會議音響的使用出現(xiàn)混響延時不當(dāng)現(xiàn)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會場的大小影響聲場混響中反射的時間和聽覺上的時間感。
① The size of the venue affects the time of reflection in the sound field reverberation and the sense of time in hearing.
②混響時間反映聲音從聲源擴(kuò)散經(jīng)周圍吸收和反射的過程，混響時間視會場的大小而定，空間越大，混響時間也越大。要經(jīng)過音頻處置設(shè)備補(bǔ)償和修飾某些聲音的缺陷，但調(diào)整不當(dāng)，就會適得其反。若混響時間過長，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(qiáng)聲音的縱深感。延時處置也是如此。
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(xí)混響的頻率特性，調(diào)整好麥克風(fēng)拾取直達(dá)聲與反射聲的比例，增加聲音的真實感和明晰度。
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(kuò)散是反映會場聲學(xué)特性的參數(shù)，要合理設(shè)置麥克風(fēng)，補(bǔ)償會場聲擴(kuò)散條件的缺陷，同時要避開具有哆嗦回聲區(qū)域和強(qiáng)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.
The reasons and countermeasures for improper reverberation delay in the use of conference audio have been given. If you have any doubts or needs, please come to our website at any time http://www.gulfbaader.com Get to know!
