會(huì)議音響在使用期間很容易就會(huì)受到一些因素的影響而導(dǎo)致問(wèn)題的出現(xiàn)，比如說(shuō)它的音頻會(huì)受到干擾，然后就會(huì)出現(xiàn)失真、聲音失調(diào)等問(wèn)題，下面展開(kāi)來(lái)講講吧。
Conference audio in use is easy to be affected by some factors and lead to problems, for example, its audio will be interfered, and then there will be distortion, sound imbalance and other problems, the following expand to talk about it.
失真大。它與設(shè)備的非線(xiàn)性失真和人為因素有關(guān)。其特征是聲音嘶啞、破損、尖細(xì)刺耳，嚴(yán)重時(shí)會(huì)影響聲音的清晰度、柔和度、明度豐滿(mǎn)度和現(xiàn)場(chǎng)感。引起失真的原因是多方面的，如麥克風(fēng)的靈敏度過(guò)高、擺放位置不合適、具有幻像電源的麥克風(fēng)供電不正常、調(diào)音臺(tái)的電平調(diào)整過(guò)大、均衡器的調(diào)整不適當(dāng)、設(shè)備之間的阻抗不匹配等。
Distortion. It is related to nonlinear distortion of equipment and human factors. It is characterized by hoarseness, breakage, tapering and harshness, which will affect the clarity, softness, lightness and fullness of the sound and the sense of the scene. There are many reasons for the distortion, such as the sensitivity of the microphone is too high, improper placement, abnormal power supply of the microphone with phantom power supply, the level adjustment of the mixer is too large, the adjustment of the equalizer is inappropriate, and the impedance mismatch between devices.
電平不規(guī)范。在調(diào)試會(huì)議音響之前沒(méi)有對(duì)調(diào)音臺(tái)、均衡器等設(shè)備進(jìn)行調(diào)校，造成信號(hào)電平過(guò)高或過(guò)低。另外，將不平衡的線(xiàn)路輸出與平衡的線(xiàn)路輸入直接連接，造成信號(hào)電平下降。
The level is not normal. The signal level is too high or too low because the mixer and equalizer are not adjusted before debugging the conference audio. In addition, the unbalanced line output is directly connected to the balanced line input, resulting in signal level drop.
音頻響不勻。它與設(shè)備的頻響指標(biāo)和人為因素有關(guān)，如麥克風(fēng)的指向偏離聲源、中頻和低頻衰減太多、麥克風(fēng)傳輸線(xiàn)過(guò)長(zhǎng)等，都將影響聲音還原的清晰度、層次感、豐滿(mǎn)度。
The audio tone is uneven. It is related to the frequency response index of the equipment and human factors, such as the microphone pointing away from the sound source, too much attenuation of medium frequency and low frequency, the microphone transmission line is too long, etc., will affect the clarity, layering and fullness of the sound restoration.
聲音比例失調(diào)。如果總控室、主會(huì)場(chǎng)、發(fā)言的分會(huì)場(chǎng)三者之間的聲音比例失調(diào)，就會(huì)影響其他分會(huì)場(chǎng)還原遠(yuǎn)程聲音的平衡度，造成會(huì)議的整體效果下降。
Out of proportion. If the sound ratio between the main control room, the main conference room and the sub-conference room is out of balance, the balance of the remote sound restored by other sub-conferences will be affected, resulting in the decline of the overall effect of the conference.
混響延時(shí)不當(dāng)。不同的會(huì)議類(lèi)型和拾音環(huán)境對(duì)混響和延時(shí)的要求不同，因此要根據(jù)聲學(xué)特性，調(diào)整混響和延時(shí)的參數(shù)。
Improper reverberation delay. Different meeting types and sound pickup environments have different requirements for reverberation and delay, so adjust reverberation and delay parameters according to acoustic characteristics.
會(huì)議音響音頻受干擾后會(huì)有什么情況出現(xiàn)？基本上就是以上所講的情況了，如果您發(fā)現(xiàn)了新的問(wèn)題產(chǎn)生的話(huà)，可以隨時(shí)來(lái)我們這兒
