半消聲室不僅是聲學(xué)測試的一個(gè)特殊實(shí)驗(yàn)室，而且是測試系統(tǒng)的重要組成部分，實(shí)際上它也是聲學(xué)測試設(shè)備之一，其聲學(xué)性能指標(biāo)直接影響測試的精度。噪聲與振動(dòng)分析儀是一款基于多功能數(shù)據(jù)采集(DAQ)模塊量身設(shè)計(jì)的可進(jìn)行高精度噪聲與振動(dòng)的測量采集分析的儀器，為工程技術(shù)、質(zhì)量監(jiān)督管理人員提供更為詳實(shí)的產(chǎn)品質(zhì)量檢測數(shù)據(jù)操作更加簡便，也為產(chǎn)品的研發(fā)設(shè)計(jì)、生產(chǎn)工藝、質(zhì)量控制提出指導(dǎo)性意見。具體聲學(xué)設(shè)計(jì)、制造施工安裝及現(xiàn)場實(shí)測驗(yàn)收簡單介紹等后續(xù)資料請留意瀏覽本公司的官方網(wǎng)站中的工程案例，或掃描本公司微信公眾服務(wù)號二維碼得到免費(fèi)推送，詳細(xì)資料則請到本公司的官方網(wǎng)站中的下載中心免費(fèi)下載。

Semi-anechoic chamber is not only a special laboratory for acoustic testing, but also an important part of the test system, in fact, it is also one of the acoustic testing equipment, and its acoustic performance indicators directly affect the accuracy of the test.The Noise and Vibration Analyzer is an instrument specifically designed based on a multi - functional data acquisition (DAQ) module. It can measure, collect, and analyze noise and vibration with high precision. It provides more detailed product quality inspection data for engineering technicians and quality supervision managers. The operation is simpler, and it also offers guiding suggestions for product research and development design, production technology, and quality control. For follow-up information such as specific acoustic design, manufacturing, construction and installation, and brief introduction of site measurement and acceptance, please pay attention to visit the project case on the official website, or scan the QR code of the wechat public service number to get a free push, and for detailed information, please go to the download center of the official website for free download.
