"I have Wylenn-brand acoustic beacons. They make a sound that's music to rakghoul ears."
―Sergeant Skolin[src]

Wylenn-brand acoustic beacons were devices manufactured by Doctor Wylenn that emitted sound which could be used to attract the rakghouls. In 3642 BBY Sergeant Skolin used such beacons on Taris to clear path to the enemy power generators.
