		Theatres Below is a selection of our many theatres.
		The City Theatre in Göteborg – rebuilding and expansion The Göteborg City Theatre has been rebuilt in an important way, where the audience area has been much altered in order to, among other targets, enhance the acoustics. With a totally new shape of reflectors, the covering of walls with textiles, and other actions taken, the acoustics of the audience has got a much higher quality. The speech intelligibility is very good even in areas where speech apprehension used to be poor. New sound-equipment and a stage control planned by Akustikon AB was installed on the main stage.
		The Stockholm City Theatre (Stockholms Stadsteater) A section of the Stockholm Culture House was used by the Swedish Parliament for several years, and subsequently by the European Security Conference. This section now contains the main auditorium of the Stockholm City Theatre. It was inaugurated in 1990. The auditorium has an octagonal floor plan, and its volume is acoustically adapted. It seats 750 people (600 in the stalls and 150 on two shallow balconies). Akustikon planned both the room acoustics and the building acoustics. Relatively few acoustical changes were required in the auditorium because of good existing conditions: some diffusion in the ceiling and under the balconies, and mobile fly towers with an optimised design. The auditorium has also been used for concerts by the Stockholms Blåsarsymfoniker wind orchestra, with an orchestra shell added to the stage.	"Phenomenal acoustics.... The faintest whisper seemed to carry." Dagens Nyheter newspaper, 15 May 1990 "Stockholm .. appears to have acquired a new, top-class concert hall" Dagens Nyheter newspaper, 26 Sept. 1990
		City Theatre of Reykjavik, Iceland Reykjavik's new City Theatre opened in 1989. The main auditorium has 550 seats, arranged in just 18 rows of stalls. This makes the auditorium wider than is acoustically desirable. However, angled sound reflectors on the side and back walls, along with slightly sound-diffusing ceiling reflectors, have produced critically acclaimed acoustics. The auditorium has also been used successfully for opera performances.
