Traditionally, noise control engineers often used test methods to identify noise problems and repeated test methods to solve the problems. However, now many industries such as automobiles, aerospace, heavy equipment, industrial equipment, air conditioning, heating, home appliances, etc., are more focused on introducing simulation models for simulation at the early design stage. Therefore, design evaluation and improvement can be performed before the physical prototype is manufactured, thereby greatly reducing product delivery time and R & D costs. 1.1 System design concept
