In order to solve the problem of excessive dynamic noise in the ventilation and air conditioning ducts,which cannot ensure a good working environment,numerical simulation of their noise values and design research on noise reduction schemes have been carried out.By using the hybrid simulation method to simu-late the dynamic noise of ventilation and air conditioning ducts,establishing a physical model and grid divi-sion of ventilation and air conditioning ducts,setting boundary conditions and numerical simulation results,the numerical simulation of noise is achieved.By controlling the constant flow ratio to optimize the inlet speed and the constant inlet speed to optimize the flow ratio,a noise reduction plan is formulated to promote the reduction of dynamic noise in ventilation and air conditioning ducts,and to improve the overall quality of the working environment.
