Sibanzi:
Izinto ezifunxa isandi zibhekisa kwizinto ezinomlinganiselo ophakathi wokufunxa isandi kwi-frequency engaphezulu kwe-0.2. Uninzi lwezinto ezifunxa isandi zizinto ezikhululekileyo nezingenamibhobho, ezifana ne -melamine foam , iingubo, njl.
Indima yezixhobo ezifunxa isandi kunye nezakhiwo ezifunxa isandi:
- Ukunciphisa kwaye ulungelelanise ixesha lokubuyisela;
- Ulawulo lubonakalise isandi
- Susa i-echo;
- Ukuphucula umgangatho wesandi kwaye utshintshe ukuhanjiswa kwebala lesandi.
Umgaqo wokusebenza:
Ekubeni isandi sisuka kwintshukumo yento, sibangela ukungcangcazela kumoya osecaleni kwenze amaza esandi, athi asasazeke kumoya. Ngokubhekiselele kwizinto ezifunxa isandi, xa isandi sigqithiselwa kumphezulu wesixhobo secandelo, inxalenye yamandla esandi ibonakala, inxalenye ingena kwizinto eziphathekayo, kwaye inxalenye yayo ikhuhla ngokubhekiselele kwindawo ejikelezileyo ngenxa yokungcangcazela kwezinto zecandelo okanye isandi esisasazeka ngayo. Le nxalenye iguqulwa ukusuka kumandla omsindo ukuya kumandla obushushu, kwaye amandla omsindo alahlekile, oko kukuthi, ngokuqhelekileyo kuthiwa isandi sithatyathwa yimpahla.
I-coefficient yokufunxa isandi:
Ukusebenza kwesandi sokufunxa kwesixhobo kubonakaliswa yi-coefficient yokufunxa isandi α. A sisimbuku selahleko ye-coefficient E absorption/E0 kunye ne-penetration coefficient E transmission/E0.
Ukusebenza kwesandi sokufunxa kwesixhobo akuhambelani kuphela nesakhiwo, ubukhulu kunye neempawu zomphezulu wesixhobo ngokwaso, kodwa kunxulumene nesalathiso sesiganeko kunye nokuphindaphinda kwesandi.
isicelo:
Izinto ezifunxa isandi zidla ngokusetyenziselwa ukulawula umthamo wangaphakathi kunye nomgangatho wesandi. Ngokuqhelekileyo, ubukhulu bevolumu yegumbi, ixesha lokuphindaphinda ixesha elide, kunye nokubi ngakumbi ukuthetha. Ukuze kuqinisekiswe ukuqondakala kwentetho, kuyimfuneko ukuthabatha isandi kwigumbi kunye nokulawula ixesha lokubuyisela. Njengeeholo, amagumbi okufundela, amabala emidlalo kunye neendawo zokubukela iifilimu.
Iimfuno zezinto ezifunxa izandi ezisetyenziswa kwizakhiwo zomculo ziya kuba ngqongqo. Ukusetyenziswa kwezixhobo zokufunxa isandi kufuneka kuqinisekise ukugcwala okuthile kwesandi kwaye kwandise ngokufanelekileyo ixesha lokuphindaphinda. Ukuze kuthintelwe iziphene ze-acoustic ezifana ne-echo, impendulo ye-acoustic, kunye nokugxilwa kwesandi, izixhobo ezithatha isandi zingasetyenziselwa eludongeni lwangemva, iileyili ze-terrace kumgangatho wesibini, iindonga zecala kunye nezinye iindawo.
Izixhobo zokufunxa isandi ezisetyenziselwa ukuyila indawo ye-acoustic yesakhiwo nazo kufuneka ziqwalasele ngokubanzi ukusetyenziswa kwezinto, kubandakanywa nokusebenza kwesandi sokufunxa kunye neempawu zokuhombisa, amandla, ukukhuselwa komlilo, ukufunxa ukufuma, ukusetyenzwa kunye neminye imiba.
Iindidi zesakhiwo sezinto ezifunxa isandi
Kukho iintlobo ezininzi zezixhobo ezifunxa isandi kunye nezakhiwo. Ngokwezakhiwo zabo zemathiriyeli ezahlukeneyo, zinokwahlulwa zibe zezi ndidi zilandelayo:
(1) Izinto ezifunxa isandi ezinemingxuma: izinto ezifunxa isandi ezinemicu, izinto ezifunxa isandi esineengqukuva kunye nezinto ezifunxa isandi ezinegwebu ;
(2) Ulwakhiwo olufunxa isandi esivakalayo: isandi esinye, ipleyiti enemingxuma enesandi esakhiweyo esifunxa isandi, ipleyiti ebhityileyo ekwaziyo ukufunxa isandi;
- Isakhiwo esikhethekileyo esifunxa isandi: ifilimu encinci ye-resonance-resonance sound-absorbsorbeing structure.
Uhlobo lokuthomalalisa oluxhathisayo
Izinto ezixhathisayo zokuthomalalisa ezithambileyo ziyaziwa njenge-melamine foam kunye noboya beglasi. Izinto ezirhabaxa eziqinileyo ziquka isinyithi, i-ceramic, kunye ne-synthetic resin porous materials, phakathi kwazo izinto ezifunxa ialuminiyam ezifunxa isandi ziye zatsala umdla wabantu. Isizathu sesokuba izinto zesinyithi ezinamathambo ziyimizimba eyomeleleyo kwaye ayifuni kukhuselwa ngezinto zomphezulu ezinemingxuma njengezinto ezithambileyo ezinamathambo. Abayi kuguga okanye basasazeke ukungcolisa imo engqongileyo emva kokusetyenziswa kwexesha elide. I-coefficient yokufunxa isandi emva kokufunxa ukufuma okanye ukufuma ayisayi kuchaphazela ukusebenza kwayo kokufunxa isandi.
Uhlobo lokungcangcazela kwefilim ebhityileyo
Ifilim encinci ishukuma izixhobo ezifunxa isandi zihlala zincanyathiselwe kwezinye izinto, ezifana nefoyile yealuminiyam kwifiber yealuminiyam efunxa isandi. Kukho kwakhona ifilimu ye-polyethylene ye-microperforated, enokuthi ifakwe kwiglasi yeefestile eziqhelekileyo. Ukusebenza kokufunxa isandi: Ineempawu ezibalaseleyo zokufunxa isandi esiphakathi.
Isibambisi sesandi sesithuba
Umahluko phakathi kwezifunxi-sandi esisemkhathini kunye nezakhiwo ezifunxi-sandi ngokubanzi kukuba azidibaniswanga neendonga eziqinileyo ezifana neesilingi kunye neendonga ukuze zenze isakhiwo esifunxi-sandi, kodwa ziinkqubo ezizimeleyo. Unyango lokufunxi-sandi esingaphakathi lubandakanya ukufaka izixhobo ezifunxi-sandi kwiindawo ezahlukeneyo zangaphakathi ngexesha lokwakhiwa nokulungiswa kwesakhiwo. Nangona kunjalo, izinto ezifunxi-sandi: izifunxi-sandi esisemkhathini zinokulungiswa kwaye ziphakanyiswe kwindawo. Ngokwenyani, isifunxi- sandi asilo sakhiwo sitsha esifunxi-sandi, kodwa ngenxa yeemeko ezahlukeneyo zokusetyenziswa, iimpawu zokufunxi-sandi nazo zahlukile. Ukusixhoma kwindawo enobuninzi bokuhamba kwamandla esandi (njekufutshane nomthombo wesandi okanye apho ukubonakaliswa kugxile khona) kunokufezekisa iziphumo ezingcono.
Isibambisi sesandi esinamandla
Iiweji ezifunxa isandi ziqhele ukusetyenziswa kwizakhiwo ezomeleleyo ezifunxa isandi kumagumbi anechoic, kunye ne-interface efakwe iithayile izinto ezirhabaxa.
Ikhontse
Ikhethini ikumgama othile ukusuka eludongeni kunye neglasi yefestile, njengokungathi kukho umgca womoya emva kwezinto ezinobungozi. Nangona ingavalwanga ngokupheleleyo, isenesiphumo esithile sokufunxa isandi kwizandi eziphakathi neziphezulu.
Ukungena emqolombeni
Ukuvulwa okuvulekileyo kwibala lesandi sangaphandle esikhululekile sikhupha isandi ngokupheleleyo kwimbono yangaphakathi, kunye ne-coefficient yokufunxa isandi se-1 kuzo zonke iifrikhwensi. Inempembelelo enkulu kwimiba yokuvakala kwegumbi. Ukuba umngxuma awujonganga indawo yesandi sasimahla, i-coefficient yokufunxa isandi iya kuba ngaphantsi kwe-1.
Abantu kunye nefenitshala
Abantu kunye nefenitshala nabo banokufunxa isandi, ngoko ke zizinto ezitsala isandi. Umthamo wokufunxa wezinto eziqhelekileyo zokufunxa isandi kunye nezakhiwo zingabalwa ngokusekelwe kwimveliso ye-coefficient yokufunxa isandi kunye nommandla osebenzayo. Ke ngoko, iimpawu zokufunxa isandi zibonakaliswa ngumthamo wokufunxa womntu ngamnye okanye ifenitshala nganye. Imveliso yazo kunye nenani (okanye inani lamaqhekeza) ngumthamo opheleleyo wokufunxa.
Ngophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe bale mihla, kuya kubakho iintlobo ezininzi kunye nemisebenzi yezixhobo ze-acoustic. Ukuze kuhlangatyezwane nemfuno ekhulayo yabantu yezinto ezifunxa isandi, ukusetyenziswa kwezinto ezifunxa isandi kuya kuba kuninzi ngakumbi kwixesha elizayo.
