AUDINT Unsound Systems (The Academy of Arts, Berlin. 2009)

The operation was codenamed Wanderin' Soul. Engineers spent weeks recording eerie sounds. They were similar to the sounds employed during a scary radio show or movie. Very creepy and designed to send shivers down the back. These cries and wails were intended to represent souls of the enemy dead he had failed to find the peace of a proper burial. The wailing soul cannot be put to rest until this proper burial takes place. The purpose of these sounds was to panic and disrupt the enemy and cause him to flee his position.

Helicopters were used to broadcast Vietnamese voices pretending to be from beyond the grave. They called on their descendants in the Viet Cong to defect, to cease fighting.
