COOL SOUND TEST! TEST UR EARS AND SPEAKERS AT THE SAME TIME

[Angelface]

Funny test especially to understand the difference between loudness and volume. However speakers are also made for humans meaning that they poorly or don't play sounds humans cannot hear. So don't expect to hear dolphins' songs from them.
