Kwizixhobo zeaudio, ubuntu bokuziva bezixhobo zesithethi kudluliselwa ekubeni kukwazi kwako ukuguqula umbane ukuba kuvakale okanye kuvakale kumbane.

Nangona kunjalo, inqanaba lemvakalelo kwi-Audio Audio yekhaya alihambelani ngqo okanye lichaphazele umgangatho wesandi.

Ayinakuba lula okanye icinge ukuba ukuphakamisa ubuntununtunu besithethi, uphawu olungcono. Ewe kunjalo, ayinakukhanyela ngqo ukuba isithethi esinemvakalelo esezantsi kufuneka ibe nomgangatho wesandi esibi. Imvakalelo yesithethi ihlala ithatha i-1 (i-watt, w) njengamandla egalelo. Beka i-microfoni yovavanyo ngqo phambi kwesithethi, kunye nesithethi esinemilinganiselo emibini epheleleyo, bebeka i-microfoni embindini yeeyunithi ezimbini zikaSomlomo. Umqondiso wegalelo ngumqondiso wengxolo, kunye nenqanaba lesandi elilinganayo ngeli xesha kukuziva kaSomlomo.

Isithethi esinempendulo ephindaphindiweyo enobuninzi inamandla amakhulu, imvakalelo ephezulu yenza ukuba kube lula ukuba kuvakale, amandla aphezulu enza ukuba ikhuseleke kwaye ikhuseleke, ineejika ezilungeleleneyo kunye nenqanaba elifanelekileyo kunye nokufanelekileyo. Ke ngoko, inokwenzeka ngokwemvelo kwaye ngokwemvelo ivelisa izandi ezahlukeneyo, kwaye isandi sinembono eqinileyo ye-hierararchy, ukwahlukana kakuhle, ukukhanya, ukucaciswa, kunye nokuthamba. Isithethi esinemvakalelo ephezulu kunye namandla aphezulu akukho lula kakhulu ukuba sivakale, kodwa okona kubaluleke ngakumbi, inqanaba lalo loxinzelelo lwesandi ngaphakathi kwenqanaba elizinzileyo nelikhuselekileyo linokufunyanwa ngaphandle kokuqhuba amandla amaninzi ukuqhuba.

Zininzi iimpawu ezidumileyo zeZithethi eziPhezulu eziPhezulu emarikeni, kodwa imvakalelo yazo ayiphezulu (phakathi kwe-84 ne-84 ne-8 ukuya kwe-8 ne-88 db), kuba ukwanda kwemvakalelo kuza ngexabiso lokuphambuka.

Ke njengesithethi esiphezulu sokungafunekiyo, ukuze kuqinisekiswe inqanaba lokuveliswa kwesandi kunye nokukwazi ukuzala, kuyimfuneko ukunciphisa ezinye iimfuno zobuntununtunu. Ngale ndlela, isandi sinokuba lilinganiselwe ngokwemvelo.

Inqanaba le-M-PampP esebenzayo

Ngaba ukuphakama kwemvakalelo yenkqubo yesandi, engcono, okanye kungcono ukuba usezantsi?

Ukuphakamisa imvakalelo, ngcono. Ukuphakamisa ubuntununtunu besithethi, ukuphakama kwenqanaba lesandi lesithethi phantsi kwamandla afanayo, kwaye esona sandi sasikhutshelwe nguSomlomo. Inqanaba loxinzelelo lwesandi eliveliswe sisixhobo kwindawo ethile kwinqanaba elithile lokufaka (amandla). Inqanaba loxinzelelo lwesandi = 10 * Amandla eLog + uvakalelo.

Ngokusisiseko, kukuphindaphinda kwayo yonke inqanaba lenqanaba lesandi, inqanaba lerejista yesandi linyuka nge-1DB, kodwa kulo lonke unyuko lwe-1db kwimvakalelo, inqanaba lesandi linokonyuka nge-1db. Ukusuka koku, ukubaluleka kobuchule kunokubonwa. Kwishishini le-Audio Audio, i-87DB (2.83v / 1m) ithathwa njenge-parameter ephantsi kwaye ikwayezithethi ezincinci (i-intshi ezi-5). Imvakalelo yezithethi ezingcono ziya kudlula kwi-90db, kwaye ezinye zinokufikelela ngaphezulu kwe-110. Ngokubanzi, ubungakanani besithethi, ukuphakama kwemvakalelo

Isithethi esinendlela ezimbini esipheleleyo
