摘　要:噪聲測(cè)量?jī)x已由一般的聲級(jí)計(jì)發(fā)展到噪聲實(shí)時(shí)分析儀。對(duì)普通聲級(jí)計(jì)和精密型聲級(jí)計(jì)產(chǎn)品及功能作了簡(jiǎn)要分析，重點(diǎn)介紹了國(guó)內(nèi)外常見的噪聲實(shí)時(shí)分析儀產(chǎn)品，展望了國(guó)內(nèi)外噪聲測(cè)量?jī)x的發(fā)展趨勢(shì)。[著者文摘]

Development of Noise Measuring InstrumentSHEN Qiu-xia, YAO Qing, LAI Feng-xiang, ZHANG Zhi-tao 1. College of Informatics and Electronics, Zhejiang Sci-Tech University, Hangzhou 310018, China; 2. China National Rice Research Institute, Hangzhou 310016, ChinaAbstract:Noise measuring instrument is developed from the general sound level meter to real-time analysis instrument. Firstly, basic and precision sound level meters＇ products and functions are analyzed. Then, the common real-time analyzer products at home and abroad are introduced. Finally, the internal and external noise measuring instrument trend of development is discussed.[著者文摘]
