This article has written about possibility to build air-opened turning auditorium for summer theatre in park part of town Èeské Budìjovice. Sound breeds sounds making communication and concentration difficult. The first part has treatised about measuring noise . In present time there is turning auditorium in castle garden of Èeský Krumlov Castle. That´s why the first measuring was made during Dvoøák´s Rusalka opera in Èeský Krumlov. The second measuring of noise was made in specified place in Stromovka part . Based on those datas we have done comparisons between both places Èeský Krumlov and Stromovka Park in Èeské Budìjovice from the point of view of background noise there. Place situated in Stromovka´s Park of Èeské Budìjovice has been interfered with traffic noise from near highroad E55. The second part has treatised about comparisons measuring noise datas on Èeský Krumlov and in Èeské Budìjovice . Performances are undertaken from 21.30 untill 24 o´clock. That´s why the background level was measured in this time , too. Noise levels ( background noise) has been LAeq t= 1 min. = 41-48 dB(A) .Mearuring of noise was made for 1-minute intervals in both places. In Èeský Krumlov there has been measered the back ground noise LAeq t= 1 min = 31-33 dB(A). The second part has treatised about anti-noise adjustments for this specified place . From measuring datas we can say it is evident this place without making anti-noise adjustments it is no possible to use for air-opened audiorium for summer theatre.
