| Abstract: | To renovate halls with poor sound effect by means of architectural acoustics is a rather new subject both at home and abroad.With measurement of reverberation time and fren-quency spectrum,as well as careful analysis and calculation,we adopted suitable sound absor-pttion materials in the renovation of Laoshan Cinema to adjust the reverberation time and frenquency spectrum of the hall and got satisfactory effect.The keys of the method are to desigh sound absorption structure elabratively and keep the acoustical parameters in line with the theoretical data.It is a simple but effective method. |
