Calculation and simulation of loudspeaker power based on cultural complex

Abstract

Research on how to calculate the power of loudspeaker in sound reinforcement system of the cultural complex has been studied seldom, this paper analyzes the calculation methods proposed by domestic and foreign scholars, on this basis, put forward the improved method that can calculate the total loudspeaker power according to the space volume of the hall(LPSV). Using the existing algorithm and the LPSV in this paper, the speaker power in the cultural complex is calculated respectively, and the total power of the loudspeaker required in the hall can be directly obtained by using the LPSV through the volume of the hall. The 3D model of the hall is established by EASE, which is used to calculate and simulate the sound reinforcement technical parameters such as analogical pressure level, articulation loss, and rapid speech transmission index. In the aspects of maximum sound pressure level, sound field nonuniformity, and transmission frequency characteristics, according to the above analysis of the data, it meets the “Design specification of hall sound amplification system” (GB50371-2006). This study provides a theoretical basis for loudspeaker configuration of sound reinforcement system in cultural complex and has great application value.
