Nyob rau hauv lub tshav pob ntawm acoustic engineering thiab sab hauv ib puag ncig optimization, suab -absorbing vaj huam sib luag, vim lawv nqus tau zoo ntawm lub suab nthwv dej zog, tau dhau los ua cov khoom siv tseem ceeb rau kev txhim kho reverberation thiab txo suab nrov. Lawv qhov kev ua tau zoo yog cuam tshuam nrog cov khoom xaiv; Cov khoom sib txawv muaj cov qauv sib txawv ntawm lub cev thiab cov tshuab nqus suab, thiab tsim nyog rau kev siv sib txawv.
Cov khoom siv fiber ntau yog cov khoom siv dav tshaj plaws, sawv cev los ntawm polyester fiber, iav ntaub plaub, thiab pob zeb wool. Cov ntaub ntawv no muaj ib lub network ntawm interconnected micropores. Thaum lub suab tsis tawm tsam, lawv ua rau huab cua vibrations nyob rau hauv lub pores thiab kev sib txhuam nrog lub pore phab ntsa, converting suab zog mus rau hauv tshav kub. Polyester fiber panels yog lub teeb yuag, yooj yim rau kev ua, thiab muaj qhov nruab nrab zoo - mus rau - siab zaus suab nqus kev ua tau zoo, nrog rau cov nplaim hluav taws thiab cov khoom zoo ib puag ncig. Lawv feem ntau siv hauv chav sib tham, xinesmas, thiab chaw ua haujlwm. Cov iav wool thiab pob zeb wool ua tau zoo tshwj xeeb hauv qhov qis - mus rau - nruab nrab zaus ntau yam, nrog cov suab nrov nqus cov coefficients ruaj khov, thiab feem ntau yog siv rau hauv cov nroj tsuag thiab gymnasiums uas tsawg - tswj lub suab nrov yog qhov tseem ceeb. Txawm li cas los xij, kev tiv thaiv kev tiv thaiv yog tsim nyog thaum lub sij hawm installation los tiv thaiv fiber ntau dispersion.
Perforated panels thiab kab noj hniav sib xyaw cov qauv yog cov kev daws teeb meem rau qis - zaus suab nqus. Cov ntaub ntawv hauv paus muaj xws li ntoo, gypsum board, lossis hlau daim hlau, nrog rau qhov chaw perforated nrog ib lub qhov taub thiab qhov sib txawv. Ib txheej huab cua raug tso tseg los ua Helmholtz resonator lossis membrane resonance qauv. Cov khoom siv no tau txais txiaj ntsig tshwj xeeb qis- zaus suab nthwv dej los ntawm kev cuam tshuam resonance, thaum tuav qee qhov kev txiav txim siab zoo nkauj thiab lub zog. Nws yog qhov tsim nyog rau kev hais kwv txhiaj hauv tsev, kaw cov studios, thiab lwm qhov chaw nrog cov kev cai nruj rau lub suab purity, tab sis yuav tsum tau tsim cov qauv tsim ntawm perforation tsis thiab kab noj hniav qhov tob raws li lub hom phiaj ntau zaus.
Polymer elastomers thiab cov ntaub ntawv ua npuas ncauj tau pom ntau siv nyob rau hauv xyoo tas los no, xws li polyurethane ua npuas ncauj thiab melamine resin ua npuas ncauj. Lawv kaw -cell los yog semi{2}}qhib- cell qauv muab cov ntaub ntawv zoo heev lub suab nqus thiab cushioning zog, thiab lawv yog lub teeb yuag thiab noo noo- pov thawj, ua rau lawv haum rau huab cua puag ncig los yog mobile acoustic li. Qee cov npuas dej, tom qab nplaim taws- hloov kho qhov tsis zoo, tuaj yeem ua tau raws li cov qauv kev nyab xeeb rau cov chaw pej xeem, tab sis lawv lub suab haum zoo sib xws hauv qhov siab - ntau zaus yog me ntsis qis dua rau cov khoom siv fiber ntau.
Tsis tas li ntawd, cov ntaub ntawv ntuj xws li cork thiab xyoob fiber ntau yog nyiam vim lawv cov khoom zoo ib puag ncig. Qhov ntxeem tau, elastic qauv ntawm cork muab lub suab nrov zoo nyob rau hauv nruab nrab - mus rau - ntau zaus, thiab tseem muaj cov thermal rwb thaiv tsev thiab tiv thaiv - cov khoom plam; xyoob fiber ntau panels, ntawm qhov tod tes, ua ke cov kev ruaj ntseg ntawm cov nroj tsuag -raws li cov ntaub ntawv uas zoo heev mechanical stability, ua rau lawv haum rau ntsuab vaj tej yaam num.
Zuag qhia tag nrho, kev xaiv ntawm lub suab acoustic- nqus cov ntaub ntawv vaj huam sib luag yuav tsum muaj kev xav zoo ntawm lub suab nqus spectrum, kev hloov pauv ib puag ncig, kev tswj hwm kev nyab xeeb, thiab kev xav kom zoo nkauj. Kev nkag siab tob txog cov txheej txheem thiab cov yam ntxwv ntawm cov khoom sib txawv yog qhov tseem ceeb kom ua tiav qhov kev sib npaug zoo ntawm kev ua haujlwm ntawm acoustic thiab engineering practicality.
