The sound machine museum shows the entire range of mechanical musical instruments. The permanent exhibition illustrates in a cheerful way how these jukeboxes were integrated into the cultural and social life of bygone eras and how they shape and enrich our lives to this day.

Everything from cylinder music boxes, flute cabinets, puppet machines to self-playing pianos, orchestrions and phonographs can be seen. The funfair and concert organs, which can be admired in the large organ hall, are extremely impressive. Based on the corresponding epochs, the rooms are designed in the style of the Gründerzeit, Art Nouveau and Art Deco.
