The Construction of the Iffland-Theater in Berlin by Carl Gotthard Langhans, 1800

The Prussian architect Carl Gotthard Langhans specialized in the construction of acoustic rooms and auditoria like theaters, churches, and amusement-halls. He publicized his theoretical conceptions in 1800 in an essay in which he summarized his lifelong experience with optic and acoustic principles in theater design. Langhans developed a systematic structure for acoustic rooms, based theoretically on the books of Pierre Patte and Gabriel Pierre Martin Dumont of the Académie d'Architecture in Paris and practically on the architectural principles of traditional German baroque churches like Steinhausen and Steingaden by Dominikus Zimmermann.
