Abstract
In the practice of noise reduction in rooms, in addition to conventional flat sound-absorbing linings, rocker-type structures are also used, placed on the ceilings of rooms in the form of various systems. Currently, there are no simple methods for evaluating the acoustic efficiency of such systems, which significantly limits their use, and in particular, the use of rocker systems of the caisson type. The article proposes a numerical method for calculating the acoustic efficiency of a coffered curtain wall system based on a geometric ray tracing method with different types of sound reflection from fences. It is shown that the method can be used when choosing the dimensions of the coffered structure of the wings based on the sound-absorbing characteristics of the curtain elements and the sound absorption of the ceiling. The method at the early stages of object design will allow for a preliminary assessment of the impact of various parameters of the curtain wall systems on their acoustic and economic efficiency.
