导阀的轴向开口很小，仅0.003～0.006厘米。过流面积很小，流速很高，可达200米/秒，易引起压力分布不均匀，使锥阀径向力不平衡而产生振动。另外锥阀和锥阀座加工时产生的椭圆度、导阀口的脏物粘住及调压弹簧变形等，也会引起锥阀的振动。所以一般认为导阀是发生噪声的振源部位。由于有弹性元件（弹簧）和运动质量（锥阀）的存在，构成了一个产生振荡的条件，而导阀前腔又起了一个共振腔的作用，所以锥阀发生振动后易引起整个阀的共振而发出噪声，发生噪声时一般多伴随有剧烈的压力跳动。先导式溢流阀发出的机械噪声，一般来自零件的撞击和由于加工误差等产生的零件磨擦。在先导型溢流阀发出的噪声中，有时会有机械性的高频振动声，一般称它为自激振动声。
