Nyob rau lub sijhawm no, txhawm rau sib tham thiab daws nrog ntau yam kev lag luam thiab tsoomfwv cov teeb meem.Txawm hais tias tsoomfwv, tsev kawm ntawv, kev lag luam, lossis tuam txhab yuav xaiv qee lub rooj sib tham ntau lub rooj sib tham.Txawm li cas los xij, yog tias lub suab tsim tsis tau ua tiav zoo ua ntej kev kho kom zoo nkauj sab hauv, tom qab ntawd lub suab nrov sab hauv thiab kev rov qab los yuav ua rau muaj kev cuam tshuam loj rau kev tuav lub rooj sib tham.Qhov no kuj yog ib qho teeb meem uas peb nquag ntsib.Cov thawj coj nyob rau ntawm theem yog eloquent, tab sis cov neeg uas nqis los mloog tsis tau dab tsi cov thawj coj ntawm lub theem tab tom tham txog thaum lub "buzzing".Yog li ntawd, sab hauv tsev acoustics yog qhov tseem ceeb tshaj plaws.Yuav ua li cas tshem tawm sab hauv tsev ncha thiab reverberation yog ib qho kev ntxhov siab heev.Nov yog qee qhov kev daws teeb meem yooj yim rau koj.
Nyob rau hauv qhov project kho kom zoo nkauj acoustic, txhawm rau koom tes nrog lub suab kaw lus kom tau txais lub suab zoo tag nrho, kev tsim acoustic thiab kev kho mob ntawm lub tsev yog qhov tseem ceeb heev.Txawm li cas los xij, tib neeg muaj ntau yam tsis meej pem hauv cov phiaj xwm kho kom zoo nkauj niaj hnub no, yog li ntawd lub suab cuam tshuam ntawm cov tsev kho kom zoo nkauj nrog cov peev txheej loj yog feem ntau nyuaj kom ua tiav lub hom phiaj xav tau, ua rau muaj kev khuv xim ntau.Cov hauv qab no yog cov lus piav qhia luv luv ntawm yuav ua li cas thiaj li ua tiav acoustic kho kom zoo nkauj tsim thiab pov tseg:
Ua ntej tshaj plaws, txhawm rau ua kom lub suab zoo zoo, kev kho kom zoo nkauj acoustic yog qhov yuav tsum tau ua ua ntej.Qhov thib ob, nws yog lub luag haujlwm ua los ntawm lub suab kaw lus thiab cov khoom siv.Uas yog hais tias: kho kom zoo nkauj tsim thiab kev tsim kho yuav tsum ua raws li nruj thiab scientific "acoustic kho kom zoo nkauj" thiab ua tau raws li qhov yuav tsum tau ntawm cov kev taw qhia txog kev txawj ntse nyob rau hauv thiaj li yuav xyuas kom meej lub suab zoo.Txawm li cas los xij, Party A thiab tus kws kho kom zoo nkauj yuav tsis quav ntsej qhov tseem ceeb ntawm "acoustic kho kom zoo nkauj";kho kom zoo nkauj feem ntau txwv rau kev kho pob yooj yim, xav tias qhov no txaus.Qhov tseeb, qhov no yog deb ntawm qhov tiag tiag acoustic kho kom zoo nkauj.Qhov no yuav ua rau lub suab tsis zoo hauv lub tsev (txawm tias cov khoom siv hluav taws xob hluav taws xob zoo li cas, lub suab yuav tsis zoo!).Lub tog kho kom zoo nkauj tsis tau ua tiav nws cov luag haujlwm, thiab feem ntau ua rau lub tshuab hluav taws xob-acoustic tsim thiab tus tsim ua lub luag haujlwm, ua rau tsis tsim nyog entanglements.
Architectural Acoustics Index Thov (Acoustic Renovation Thov):
1. Cov suab nrov tom qab: tsawg dua lossis sib npaug ntawm NR35;
2. Kev ntsuas suab rwb thaiv tsev thiab kev co kev sib cais: yuav tsum muaj qhov zoo ntawm lub suab rwb thaiv tsev thiab kev ntsuas kev co nyob hauv lub tsev.Lub suab rwb thaiv tsev thiab kev vibration cais cov cim qhia raws li GB3096-82 "Code for Environmental Noise in Urban Areas", uas yog: 50dBA thaum nruab hnub thiab 40dBA thaum hmo ntuj;
3. Architectural Acoustic Index
1) Resonance, ncha, flutter ncha, chav suab sawv nthwv dej, suab tsom, suab diffusion;
Lub tsev qhov rooj, qhov rais, qab nthab, iav, rooj zaum, kho kom zoo nkauj thiab lwm yam khoom siv nyob rau hauv txhua chav yuav tsum tsis txhob muaj resonance tshwm sim;yuav tsum tsis muaj qhov tsis xws luag xws li echoes, trembling echoes, chav suab sawv nthwv dej, thiab lub suab tsom rau hauv cov chav tsev, thiab lub suab nrov diffusion yuav tsum sib npaug.
2) Reverberation lub sijhawm
Reverberation lub sij hawm yog lub ntsiab Performance index yuav tsum tau tswj nyob rau hauv acoustic kho kom zoo nkauj, thiab nws yog lub ntsiab ntawm acoustic kho kom zoo nkauj.Txawm hais tias lub suab zoo nkauj zoo nkauj lossis tsis zoo, qhov ntsuas no yog qhov kev txiav txim siab, thiab nws tseem yog tib lub tsev acoustic parameter uas tuaj yeem ntsuas los ntawm cov cuab yeej tshawb fawb.
