Ib lub chamber anechoic yog ib qho chaw uas tsis cuam tshuam suab. Cov phab ntsa ntawm lub chamber anechoic yuav raug paved nrog cov ntaub ntawv nqus suab nrog cov khoom zoo nqus suab. Yog li ntawd, yuav tsis muaj kev cuam tshuam ntawm cov suab nthwv dej hauv chav. Lub chamber anechoic yog ib lub chaw kuaj mob tshwj xeeb siv los sim lub suab ncaj qha ntawm cov neeg hais lus, cov chaw hais lus, lub mloog pob ntseg, thiab lwm yam. Nws tuaj yeem tshem tawm kev cuam tshuam ntawm echoes hauv ib puag ncig thiab sim tag nrho cov yam ntxwv ntawm tag nrho lub suab. Cov khoom siv nqus suab siv hauv lub chamber anechoic xav tau lub suab nqus coefficient ntau dua 0.99. Feem ntau, ib txheej gradient absorbing siv, thiab wedge lossis conical qauv feem ntau siv. Iav wool siv ua cov khoom nqus suab, thiab ua npuas mos kuj siv. Piv txwv li, hauv 10 × 10 × 10m chav kuaj mob, ib lub wedge nqus suab ntev 1m raug tso rau ntawm txhua sab, thiab nws qhov zaus qis-zaus txiav-tawm zaus tuaj yeem ncav cuag 50Hz. Thaum kuaj hauv chav anechoic, qhov khoom lossis qhov chaw suab uas yuav kuaj yuav tsum muab tso rau ntawm lub nylon mesh nruab nrab lossis lub mesh hlau. Vim tias hom mesh no muaj qhov hnyav tsawg, tsuas yog cov chaw suab sib dua thiab me me xwb thiaj li kuaj tau.
Chav Anechoic Ib Txwm
Nruab cov daim txhuam cev corrugated thiab cov phaj hlau uas nqus suab me me hauv cov chav anechoic ib txwm muaj, thiab cov nyhuv rwb thaiv suab tuaj yeem ncav cuag 40-20dB.
Chav Anechoic Semi-Professional
5 sab ntawm chav (tshwj tsis yog hauv pem teb) yog npog nrog daim txhuam cev nqus suab zoo li tus hlais lossis cov ntaub iav.
Chav Anechoic Kev Ua Haujlwm Tag Nrho
Rau 6 sab ntawm chav (xws li hauv pem teb, uas dai ua ib nrab nrog cov hlau xaim) yog npog nrog daim txhuam cev nqus suab zoo li tus hlais lossis cov ntaub iav.
