會議音響在使用期間很容易就會受到一些因素的影響而導致問題的出現，比如說它的音頻會受到干擾，然后就會出現失真、聲音失調等問題，下面展開來講講吧。
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。它與設備的非線性失真和人為因素有關。其特征是聲音嘶啞、破損、尖細刺耳，嚴重時會影響聲音的清晰度、柔和度、明度豐滿度和現場感。引起失真的原因是多方面的，如麥克風的靈敏度過高、擺放位置不合適、具有幻像電源的麥克風供電不正常、調音臺的電平調整過大、均衡器的調整不適當、設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.
電平不規范。在調試會議音響之前沒有對調音臺、均衡器等設備進行調校，造成信號電平過高或過低。另外，將不平衡的線路輸出與平衡的線路輸入直接連接，造成信號電平下降。
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。它與設備的頻響指標和人為因素有關，如麥克風的指向偏離聲源、中頻和低頻衰減太多、麥克風傳輸線過長等，都將影響聲音還原的清晰度、層次感、豐滿度。
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。如果總控室、主會場、發言的分會場三者之間的聲音比例失調，就會影響其他分會場還原遠程聲音的平衡度，造成會議的整體效果下降。
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.
混響延時不當。不同的會議類型和拾音環境對混響和延時的要求不同，因此要根據聲學特性，調整混響和延時的參數。
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.
