SeniorAcoustic tau tsim ib lub chamber anechoic tshiab uas muaj tus qauv siab rau kev kuaj lub suab zoo, uas yuav pab txhim kho qhov tseeb ntawm kev kuaj pom thiab kev ua haujlwm ntawm cov cuab yeej ntsuas suab.
● Thaj chaw tsim kho: 40 square meters
● Qhov chaw ua haujlwm: 5400 × 6800 × 5000mm
● Chav tsev tsim kho: Guangdong Shenniob Acoustic Technology, Shengyang Acoustics, China Electronics South Software Park
● Cov cim qhia suab: qhov zaus txiav tawm tuaj yeem qis li 63Hz; lub suab nrov tom qab tsis siab dua 20dB; ua tau raws li qhov yuav tsum tau ua ntawm ISO3745 GB 6882 thiab ntau yam qauv kev lag luam
● Cov ntawv thov ib txwm muaj: anechoic chambers, semi-anechoic chambers, anechoic chambers thiab anechoic boxes rau kev nrhiav cov xov tooj ntawm tes lossis lwm yam khoom sib txuas lus hauv ntau yam lag luam xws li tsheb, electromechanical lossis electro-acoustic products.

Kev taw qhia txog chav anechoic:
Ib chav anechoic txhais tau hais tias ib chav uas muaj lub suab dawb, uas yog, tsuas muaj lub suab ncaj qha tab sis tsis muaj lub suab rov qab los. Hauv kev xyaum, nws tsuas yog hais tau tias lub suab rov qab los hauv chav anechoic yog me me li sai tau. Yuav kom tau txais cov txiaj ntsig ntawm lub suab dawb, rau qhov chaw hauv chav yuav tsum muaj lub suab nqus siab, thiab lub suab nqus coefficient yuav tsum ntau dua 0.99 hauv qhov ntau zaus ntawm kev siv. Feem ntau, cov wedges silencing raug tso rau ntawm 6 qhov chaw, thiab cov hlua hlau nets
raug ntsia rau ntawm cov wedges silencing hauv av. Lwm lub qauv yog chav semi-anechoic, qhov sib txawv yog tias hauv av tsis tau kho nrog kev nqus suab, tab sis hauv av tau paved nrog cov vuas lossis terrazzo los ua ib qho iav nto. Cov qauv anechoic no yog sib npaug rau ib nrab ntawm lub chamber anechoic ob npaug hauv qhov siab, yog li peb hu nws ua semi-anechoic chamber.
Ib lub chamber anechoic (lossis semi-anechoic chamber) yog ib qho chaw sim tseem ceeb heev hauv kev sim acoustic thiab kev sim suab nrov. Nws lub luag haujlwm yog los muab ib puag ncig sim suab nrov qis hauv qhov chaw dawb lossis semi-free-field.
Cov haujlwm tseem ceeb ntawm lub chamber anechoic:
1. Muab ib qho chaw tsis muaj suab nrov
2. Ib puag ncig sim suab nrov qis
