摘　　要：在录音时,表针可达40％～60％左右平均值,有时偶尔到OVU位置,录音乐时表针常集中在OVU附近,而录语言时表针主要集中在40%～60％位置,如果超出OVU时,就要注意话筒离播音位置不要太近,通过调整话筒的距离、角度等来解决上述问题。When sound being recorded, the needle may reach the mean value of about 40% -60%, occasional - ly arrive at the OVU position. When music being recorded, the needle mainly concentrates near OVU. While words being recorded, it mainly concentrate between 40% and 60%. If it surpasses OVU, the broadcast position of the microphone wont be put too near. The problms above - mentioned can be solved through adjus - ting the distance and the angle of the microphone.
