voice 2: The researchers found that this was an effective way to confuse the men. The men could not follow the chant when one loudspeaker played a little behind the others. This method worked when the chanting was delayed by as little as two hundred milliseconds. But it had the biggest effect when the chanting was delayed to one second behind the other chanting.
声音2：研究人员发现，这是迷惑志愿者的有效方式。当一个扩音器播放的录音比其他扩音器稍有延迟时，志愿者无法跟随录音一起呐喊。在呐喊录音只延迟200毫秒时，这种方法是有效的。而当呐喊录音延迟1秒钟时，这种方法可发挥出最大效果。

voice 1: Sander says that bringing the technology to real sports stadiums can be effective. But it may not be very simple. Loudspeakers at many stadiums are not complex or strong enough. Sander's system also requires special microphone recording devices. Stadiums would need to put in new sound equipment.
