Uyilo lweAcoustic luvumela iimbaleki zinxibe“ii-headphones”
Ngo-Agasti 6, 2024 # Imidlalo yeOlimpiki yaseParis #iimitha ezili-10 zokuphela kwebhodi yokuntywila, abaphumelele iimbasa zegolide ezintathu uQuan Hong chan kunye noChen Yunxi bahlala kunye, umzimba wabo, ujongeka ngokwendalo, ubonisa "indoda enkulu ehleli", intloko eneneni isanxibe i-headphones. Abantu abaninzi baye baphawula ukuba oku kukuphumla kwamandla aphezulu. Abanye abantu bayazibuza: kutheni unxibe i-headphones xa ulinde ikhefu? Uninzi lwabasebenzisi be-intanethi banike impendulo efanelekileyo, iimbaleki zilinde ukuphumla ukuze zihlukanise umoya webala lemidlalo, zigcine zigxile, ziphumle, zinciphise uxinzelelo. Ke, ngokwembono yoyilo lwe-acoustics, njengomyili we-acoustic, luhlobo luni loyilo lwe-acoustic lweendawo ezinendibano yabemi ezifana namabala emidlalo anokunceda iimbaleki?
Ngokweempawu zomzimba ze-gymnasium, sinokuzicombulula iingxaki ze-acoustic ngokumisa isandi esithatha isandi kwindawo ethe tyaba kunye nokuyila udonga lweplanga lokuthatha isandi.
Ulwakhiwo lwe-porous yebhodi yokhuni efunxa isandi ihlangabezana neemfuno zokufunxa isandi esiphakathi kunye nesisezantsi, esiphunyezwa ngokudibana kwe-acoustic impedance kunye nokubonakaliswa okuninzi, ukuchasa kunye nokuthomalalisa amaza omsindo. Xa isandi sesandi sidlula kumphezulu webhodi efunxa isandi, inxalenye yeliza yesandi iya kubonakala, kwaye inxalenye yesandi sesandi iya kungena kumphezulu webhodi, ize emva koko ifunxwe zizinto ezakhiweyo ezinentunja. kwibhodi efunxa isandi, ekugqibeleni uguqule amandla abe ngamandla amancinci obushushu. Ngaphezu koko, i-substrate yepleyiti enemingxuma eyenziwe ngomthi inokukhetha kwakhona i-MDF enobungqina bokufuma, okanye ipleyiti yeglasi yemagnesium enobungqina obuqinileyo bokufuma, obunokusebenza okunamandla okungenamanzi, akulula ukuba kudliwe, kunye nokufunxa isandi sayo. ukusebenza uzinzile.
Uphahla lwe-gym luyisitshixo sokuphucula ukucaca kwesandi. Isibambisi sesandi sesithuba siveza ngokupheleleyo zonke iindawo ngokwaso kwibala lesandi sangaphakathi ngokuxhoma, ukuze sibe nezandi ezininzi ezifunxa isandi. Isixhobo sokufunxa isandi sesithuba sidibanisa ubume obukhululekileyo bomqhaphu ofunxa isandi sangaphakathi kunye nokuvakala kwesakhiwo ukufunxa isandi kunye nokunciphisa ingxolo, enokunciphisa ixesha lokubuyisela, ukuphucula ukucaca kwesandi, kunye nokusombulula ingxaki yeziphene zesandi. njengokugxila kwisandi kunye ne-echo.
Uyilo lwe-acoustic oludityaniswe nebhodi efunxa isandi kunye nesithuba esifunxa isandi somzimba sigcina ixesha eliphakathi lokuphindaphinda amaza e-natatorium kwi-2.0s-3.5s, eliqinisekisa ukungxola nokucaca kwesandi soqeqesho lwezemidlalo kunye nemisitho yezemidlalo ukuya kumlinganiselo omkhulu. , kwaye iphucula ukuzala kwesandi kunye nengqiqo yendawo yoosompempe neetoliki.
