The World of Two Ears · In Front or Behind?

The sound plays in front and behind, in directions that mirror each other: straight ahead and straight behind, front-right and back-right, front-left and back-left. The arrival difference at the two ears is the same within each pair; only a slightly darker tone sets the back apart. After the fourth minute the order is mixed: each time, with your eyes closed, guess whether it is in front or behind. This model has no outer-ear filtering; mixing up front and back is to be expected. Headphones recommended. A listening practice with no claim of any effect.
