摘要
为测试分析并设法降低家用电器的噪声,国内外正在开展动态型消声室设计研究。结合两个测试空调器噪声的带工况精密级消声室的工程实例,分析了带工况消声室的设计要求、技术难点,介绍了所采取的主要措施及效果。
For testing and reducing the noise of home electrical appliances, the design and research of dynamic state muffler are being developed at home and abroad. Combing the two precision mufflers with machine working for testing the air conditioner's noise, this paper not only analyses the design demands and technology points, but also introduces the steps and effects. Shanghai Science and Technology Commission have passed this project. The fruit is living in the first at domestic.
