Covtxo suab nrovcoefficient (feem ntau hu ua NRC) yog ib tus lej ntau ntawm 0.0-1.0, uas piav qhia qhov nruab nrab lub suab nqus kev ua haujlwm ntawm cov khoom siv.Covtxo suab nrovCov coefficient yog qhov nruab nrab ntawm Sabine suab nqus coefficient ntsuas ntawm 250, 500, 1000, thiab 2000 Hz.

Tus nqi ntawm 0.0 txhais tau hais tias cov khoom tsis attenuate mid-frequency suab, tab sis qhia txog lub zog suab.Qhov no yog lub tswv yim ntau dua li lub cev ua tiav: txawm tias cov phab ntsa tuab tuab heev yuav ua rau lub suab nrov, thiabtxo suab nrovcoefficient yuav yog 0.05.

Ntawm qhov tsis sib xws, lub suab nrov txo coefficient ntawm 1.0 txhais tau hais tias thaj chaw acoustic nto (hauv sabin raws li chav tsev) muab los ntawm cov khoom sib npaug rau nws lub cev ob sab ntawm thaj chaw.Qib no yog cov khoom siv rau cov khoom siv suab nrov nrov (xws li 2-nti tuab ntaub-pob fiberglass vaj huam sib luag).Cov khoom siv no tuaj yeem ua tiav lub suab nrov txo coefficient ntau dua 1.00.Qhov no yog qhov tsis txaus ntseeg nyob rau hauv cov txheej txheem xeem, thiab nws yog ib qho kev txwv ntawm acoustician lub ntsiab lus ntawm ib square unit es tsis yog tus yam ntxwv ntawm cov khoom nws tus kheej.

Lub suab nrov txo qhov feem ntau yog siv los ntsuas qhov kev ua tau zoo ntawm acoustic ceilings, partitions, banners, office screens, thiab acoustic wall panels.Qee lub sij hawm siv los ntsuas qhov kev pab cuam hauv pem teb.Txawm li cas los xij,txo suab nrovyog xwbtxo suab nrov, uas tuaj yeem txo qhov cuam tshuam ntawm lub suab nrov ntawm tib neeg, tab sis nws tsis tuaj yeem cuam tshuam lub suab.Nws tseem yog ib qho tsim nyog yuav tsum nrhiav cov khoom siv suab nrov nrov.

Yog li dab tsi yog cov ntaub ntawv siab NRC suab-absorbing?Mineral fiber ntau qab nthab board thiab fiberglass board yog cov ntaub ntawv zoo dua rau lub suab nqus thiabtxo suab nrov.NRC ntawm cov pob zeb hauv av fiber ntau yog feem ntau txog 0.5, thiab nrc ntawm fiberglass board tuaj yeem ncav cuag 0.9-1.0.Peb tuaj yeem nruab cov ntaub ntawv qab nthab tsim nyog raws li qhov chaw sib txawv.
