井洞噪声：由地震炮洞喷或爆炸气体在井洞内转动引起的噪声。井洞噪声通常会持续几秒时间，对临近井洞的地震检波器影响特别大，也随着距离的增加衰减。

Noise from the shot, cause by hole blow (q.v.) or rumbling around in the borehole of the gases resulting from an explosion. Hole noise may last for several seconds. It is often excessively strong on geophone groups near the shothole and attenuates rapidly with distance.
