The latent period of constriction in the owl is only half that in the human, and the latent period of dilatation is about equal to that in the human. Similarly, the rise time of constriction in the owl is much faster than that in the human. The owl system has the characteristics of a low-band-pass filter. The owl's frequency response is over an octave lower than that of the human, but its phase lags are shorter.
猫头鹰的收缩潜伏期只有人类的一半，而扩张潜伏期则大致与人类相当。同样，猫头鹰的收缩上升时间也比人类快得多。猫头鹰系统具有低通滤波器的特性。猫头鹰的频率响应比人类低一个八度，但相位滞后更短。
