近年来,一机部一院先后设计了两个消声室,一个是蚌埠市无线电元件一厂的全消声室,功能为测试扬声器的音质、作扬声器声学性能的鉴定和有关试验;一个是一机部合肥通用所的噪声试验室(这是半消声室),功能为测试各类空调器的噪声水平和对其附件进行噪声试验的研究。蚌埠市无线电元件一厂的全消声室已建成投产。在使用过程中,厂方反映良好。我们拟在一段较长时间的生产使用后进行全面的测定总结。下面对两个消声室的设计作一简介。一、概况 1.全消声室总建筑面积为236.8m~2,其中消声室面积为72m~2,另附有办公室、仪表室、控制测定室等辅
In recent years, a unit of the hospital has designed two anechoic chamber, one is a radio unit Bengbu City, a full anechoic chamber, the function of the speaker for testing the sound quality, speaker appraisal of the acoustic properties and related tests; one is Hefei General Office of a machine noise test room (which is a semi-anechoic chamber), the function of various types of air conditioners to test the noise level and its accessories for noise test research. Bengbu radio components plant a full anechoic chamber has been completed and put into production. In the process of using, the factory reflects well. We intend to conduct a comprehensive summary of the measurement after a long period of production. The following two anechoic chamber design to make a profile. I. Overview 1. The total muffler floor area of 236.8m ~ 2, of which muffler room area of 72m ~ 2, attached to the office, the instrument room, control room, such as aids
