随着噪声控制技术的发展,国内许多生产噪声控制设备的专业工厂相继出现,商品性的噪声控制定型产品陆续大量投放市场。由于一些工矿企业的工程技术人员刚开始接触噪声控制技术工作,对各类系列消声器产品的消声机理和功能还不甚了解,以致在实际工程设计中出现套用不当的情况。如装置消声器后非但没有降噪效果,有的反而成为噪声放大器;因消声器的使用,原系统的运转工况特性改变,严
With the development of noise control technology, many specialized factories producing noise control equipment have appeared one after another, and commercial noise control stereotypes products have been put on the market one after another. As some industrial and mining enterprises engineering and technical personnel have just started to work with noise control technology, the muffler mechanism and function of various series of muffler products are not well understood, resulting in improper application in actual engineering design. Such as muffler not only after the device without noise reduction effect, and some instead become a noise amplifier; muffler due to the use of the original system operating conditions change, strict
