Listen using stereo loudspeakers
In listening to these stereo illusions through loudspeakers, it is important to have the speakers placed with one to your left and the other to your right.
The speakers should be separated as widely as possible, and you should listen some distance away from them. The effect works particularly well in a classroom or auditorium.

When listening to these sound files, it is best to use equipment with a flat frequency response, so as to avoid spectral distortion. Features that alter the signal in any way, such as spatialization features, should be turned off. And make sure that the playback amplitude is not too high and that the sounds coming from the two loudspeakers are roughly equal in loudness.
