Why is there echo or feedback sound?
回音或啸叫通常是因为麦克风太靠近音响，或者音量和混响（echo/reverb）设置太高。当声音从音响出来再次被麦克风接收到，就会形成循环，从而产生刺耳的反馈声。建议适当降低麦克风音量，拉开麦克风与音响的距离，并微调回音效果。
Echo or feedback usually happens when the microphone is too close to the speaker, or when the volume and echo/reverb settings are too high. The sound from the speaker gets picked up again by the mic, creating a loop that causes that sharp feedback noise. Lowering the mic volume, increasing the distance from the speaker, and adjusting the echo level can help improve it.
Echo atau bunyi “feedback” biasanya berlaku bila mikrofon terlalu dekat dengan speaker atau volume serta echo/reverb terlalu tinggi. Bunyi dari speaker akan masuk semula ke mikrofon dan menyebabkan bunyi melingkar yang kuat. Kurangkan volume mic, jauhkan jarak dari speaker, dan laraskan echo untuk elakkan masalah ini.
