Cov lus qhia luv luv ntawm qhov project
Lub chav xyaum ua si yog qhov chaw ua haujlwm ntau yam. Nws yog cov chaw ntau pob hauv chaw ua si nrog cov pob hauv av ntawm 2945 square metres thiab cov theem tas. Qhov ntim ntawm lub tsev sib tw yog li 48,060 cubic meters. Cov ntsiab lus acoustic yuav tsum ua kom tau cov ntsiab lus acoustic ntawm ntau yam kev sib tw me thiab nruab nrab, kev sib tham loj loj, kev ua yeeb yam thiab kev ua si. Nws lub ntsiab xav tau rau acoustic tsim yog cov lus meej, cov nkauj tag nrho, thiab tsis muaj acoustic tsis xws luag.
Cov xwm txheej sab hauv
Qhov chaw ua si uas twb muaj lawm siv perforated gypsum board thiab polyester fiber acoustic panels. Peb pom tau tias qee qhov perforated gypsum board tau raug puas tsuaj, polyester fiber acoustic vaj huam sib luag muaj thaj chaw ntau ntawm cov pwm thiab cov npoo yog yooj yim kom nqus tau hmoov av, yug cov kab mob thiab yog qhov nyuaj rau lis. Cov khoom siv tau deformed los ntawm ya raws, uas cuam tshuam tag nrho kev zoo nkauj thiab lub suab haum kev coj ua ntawm cov khoom.

Acoustic tsim hom phiaj
1) Daim ntawv qhia tas nrho cov zaus rov qab yog qhov sib npaug, thiab tsis muaj qhov pom tseeb poob hauv qhov zaus;
2) Lub suab tawm hluav taws xob hauv tag nrho cov chaw tsim nyog thiab txawm;
3) Cov twj ywm txog qhov teeb meem ntsiag to;
4) Tsis muaj qhov sawv chaw nthwv dej;
5) Tsim nyog rau txhua yam kev sib tw thiab cov kev ua si, thiab cov cuab yeej tsim kho suab tsim nyog yuav tsum muaj qhov zoo dua los tiv thaiv thiab cuam tshuam los tiv thaiv kev hnav.
Txheeb xyuas lub sijhawm reverberation
Raws li cov ntaub ntawv muab los ntawm cov neeg siv khoom, cov chav nyob sab hauv chav ua kis las yog li 48,060 square metres, muaj 1800 chav ua haujlwm ruaj ruaj, txhua qhov ntim ntawm 26.7 square metres. Tus qauv tsim qauv acoustics yog qhov tseem ceeb rau kev tswj hwm lub sijhawm rov qab thiab tshem tawm qhov cuam tshuam ntawm kev cuam tshuam ntawm kev puas tsuaj ntawm lub rooj sib hais. Raws li qhov tshwj xeeb, lub cev, kev ua haujlwm zoo thiab cov ntsiab lus ntawm lub tsev, nws tuaj yeem ua tau raws li kev ua haujlwm zoo ntawm ntau qhov kev sib tw, rooj sib tham loj thiab ntau yam kev ua yeeb yam. Cov lus hauv qab no ntawm qhov phiaj xwm tam sim no yog siv los ua lub hauv paus rau kev tsim qauv acoustics raws li cov khoom siv xaiv thiab cov tseev kom muaj ntawm cov neeg siv khoom.

Txoj kev npaj kho tshiab
Tom qab tshem cov perforated gypsum board thiab polyester fiber acoustic vaj huam sib luag, phab ntsa txais cov ntoo perforated acoustic vaj huam sib luag (loj: 128 * 2440 * 15 (hli), qauv: 13-3).
Zuag qhia tag nrho yog kwv yees li 3726 sqm los daws qhov teeb meem tsawg zaus reverberation.
Nruab cov txheej txheem keel txhawb nqa, khaws tsawg kawg 150mm kab noj hniav los ntawm phab ntsa, thiab sau nrog 50 hli tuab 48K / m³ fiberglass wool vaj huam sib luag qhwv nrog iav fiber ntaub. (Cov lus qhia ntxaws yog nyob rau hauv lub khw teeb duab)
Qhov siab ntawm cov keel tom qab tshem tawm ntawm perforated gypsum board thiab polyester fiber acoustic panels yog raws li nram no:
Cov ntawv tseem ceeb
Cov ntsiab lus ntawm lub tsev tso tawm tom qab ua tiav qhov kev hloov kho yuav tsum tsis txhob qis dua cov ntsiab lus acoustic ua ntej kev txhim kho uas twb muaj lawm. Lub suab kho tshiab tsis muaj kev puas tsuaj rau cov chaw uas twb muaj lawm (xws li cov tsev tua hluav taws, lub qhov cub hluav taws xob, cov pa pa, thiab lwm yam).
Ua ntej kev kho:
Tom qab tau kho dua tshiab (tshawb xyuas lub sijhawm so tsev kawm ntawv)
Xaiv cov ntsiab lus ntsuas ntawm chaw me
Cov qhab nia ntsuas T1-T8 raug xaiv raws li txoj haujlwm ntawm chav tsev, thiab cov ntsiab lus ntsuas cuam tshuam txog lub sijhawm rov ua dua ntawm chav ua yeeb yam hauv thaj chaw no.
Reverberation lub sijhawm tom qab kev kho:
Ntsuam xyuas cov ntaub ntawv ntsuas
Lub khoob khoob ntawm cov ntaub ntawv xeem ntawm T1-T8 cov qhab nia xeem yog cov hauv qab no:
 |  |
| (1/3 octave band) | (1/1 octave band) |
Xeem xaus
1/3 octave zaus hloov dua siab 1/1 octave band cov ntaub ntawv, lub sij hawm reverberation tau los ntawm T1-T8 npliag teb kuaj yog superimposed nrog 80% tag nrho teb reverberation lub sij hawm thaj tsam tsim los ntawm peb lub tuam txhab, thiab reverberation lub sij hawm tus nqi yog raws li kev pib tso suab qauv Tus qauv txwv sab saud yog ze heev. Xav tias qhov kev xeem ntawv yog cov ntaub ntawv tsis muaj dab tsi, cov neeg mloog lub suab zoo lub zog tsis suav nrog. Thaum 80% ntawm daim teb yog tag nrho, lub sijhawm reverberation yuav raug txo ntxiv, thiab lub sijhawm reverberation ntawm 500-1000Hz yuav raug txhim kho los ntawm ntau dua li ntawm 0.3 vib nas this. Li ntawm 1.6-1.7 vib nas this. Lub sijhawm reverberation poob nyob rau thaj tsam ntawm cov qauv tsim thiab ua tau raws li cov qauv tsim.
