Abstract: The demand for acoustic design of hall buildings has been increasing in recent years, but the existing commonly used professional acoustic software has some limitations when it meets the needs of pre-trial review. Based on the analysis of the commonality and consistency of the previous engineering cases, a modularized and shaped initial analysis platform of architectural acoustics is preliminarily developed for the selection and area of indoor sound-absorbing materials, the shape and area of diffusers, the materials and area of ceiling and floor, the coverage of sound energy, as well as the conventional architectural acoustics indexes such as reverberation time and sound pressure level uniformity. To a certain extent, this analysis platform solves the design requirements of rapid demonstration and acoustic mapping in the early stage of the solution. The experimental results show that the data validity of the analysis platform can meet the needs of rough sound field evaluation and can be used as an engineering acoustic technology.
