Freiberg is a university and former mining town in Saxony, Germany. It is a Große Kreisstadt (large county town) and the administrative centre of Mittelsachsen district.
Audible and perhaps subliminal suggestions by Bob Monroe accompany the various brainwave frequencies, which are sometimes rolled in together with other sounds such as sea surf to mask the sound frequencies where desireable.
The town was founded around 1168, after a silver discovery led to the first Berggeschrey, and has been a centre of the mining industry in the Ore Mountains for centuries.
Freiberg also has a notable cathedral containing two famous Gottfried Silbermann organs. There are two other organs made by Gottfried Silbermann in the town – one at the St. Peter’s Church (Petrikirche) and the other one at the St. James’ Church (Jakobikirche).
