前言为了更好地提高电声产品的质量和工艺水平,我们曾为某中小电声厂设计了一座专为测量扬声器声学性能用的装配式全消声室,它是一种轻型的、可装可拆可组合的、由工厂加工安装的消声室。它以高隔声量的轻型钢结构复合板作围护结构;用市场可以买到的阻尼弹簧减振器或橡胶剪切减振器提高隔板性能;通过试验选用尽可能短的高效吸声尖劈等技术措
Foreword In order to better improve the quality and craftsmanship of electroacoustic products, we have designed a prefabricated complete anechoic chamber for measuring the acoustic performance of loudspeakers for a small and medium-sized electroacoustic factory. It is a lightweight, can be installed. Removable and combinable, factory-installed anechoic chamber. It uses a high sound insulation of lightweight steel structural composite panels as a containment structure; use commercially available damper spring shock absorbers or rubber shear shock absorbers to improve the performance of the partitions; select the shortest possible high-efficiency sound-absorbing tip through the test劈 and other technical measures
