Yintoni umahluko phakathi kwesithethi esisebenza umgama opheleleyo kunye nesithethi esisebenza umgama ophakathi?
Isithethi sefrikshini yeqhezu
Izithethi zokusasazwa kwamaza, isithethi esiqhelekileyo esineendlela ezimbini, isithethi esineendlela ezintathu, ngesahluli samaza esakhelwe ngaphakathi, imiqondiso yesandi yeendawo ezahlukeneyo zamaza iyahlulwa, ize idluliselwe kwisithethi esihambelanayo. Inzuzo yesithethi see-fractional frequency kukuba ibhendi nganye yezandi ineyunithi yayo yesandi, nganye yenza imisebenzi yayo kwaye inika ukudlala kwiingenelo zebhendi yayo yezandi.

1,Isithethi esineendlela ezimbini
Isetyenziswa kwi-acoustics yeshelufu yeencwadi, isithethi se-fractional frequency sineyunithi eyahlukileyo ye-treble, kwaye i-middle bass ixutywe kunye. Ngenxa yokuba iyunithi ye-treble kunye neyunithi ye-bass zahlukile, olu phawu lolwakhiwo lwenza ububanzi beefrikhwensi eziphezulu nezisezantsi zibe ngcono, ukusuka kwi-solo yesixhobo ukuya kwi-symphony enkulu yokuhlanganiswa, inokubonakaliswa kakuhle.
2,Isithethi esineendlela ezintathu
Ineyunithi yesandi esiphakathi eyongezelelweyo xa ithelekiswa nesandi sesibini, ngoko ke ikwanazo nokusebenza ngcono kweenkcukacha zesandi. Ukuze kufezekiswe isiphumo esifanelekileyo somgangatho wesandi, abavelisi abaninzi basebenza nzima kwindawo yokwahlulahlula imvamisa. Ukukhethwa kwendawo yokwahlulahlula imvamisa kufuneka kuthathwe ngokweempawu zempendulo yemvamisa yeyunithi yesithethi. Ukuba ayimiselwanga kakuhle, iya kuchaphazela ukusasazwa kwamandla esandi, nto leyo ebangela ukuba isandi semvamisa siphelele singabi tyaba. Ngaphandle kwesicwangciso sokwahlulahlula imvamisa esingokwesayensi nesifanelekileyo, nokuba iyunithi yesithethi ingcono, ayinakushukunyiswa ukuba isebenze. Kuphela ngokwahlulahlula imvamisa okuneenkcukacha ngakumbi, iyunithi ehambelanayo inokubuyisela isandi sebhendi nganye yemvamisa, kwaye ukusebenza komgangatho wesandi kuya kuba ngcono. Ngenxa yokuba kukho iiyunithi zemvamisa ezintathu ezingaphezulu, isahluli semvamisa sikwafuna ubunzima obungakumbi, ixabiso liphezulu, ixabiso lesandi lesandi semvamisa ezintathu kwimarike yangoku liqala nge-yuan eliwaka, uphawu olwaziwayo lufikelele kwinqanaba le-yuan eliwaka elilishumi, kunokuthiwa umkhuhlane awunasiphelo. Okwangoku, kukho iintlobo ezininzi zemveliso zesithethi sendlela yomoya, ezifana nesandi se-KTV, ibhokisi yeshelufu yeencwadi, isandi semidlalo yasekhaya yomgangatho ukuya emhlabeni njalo njalo.
二、uluhlu olupheleleyo lwesithethi
Njengoko igama lisitsho, isithethi esisebenza rhoqo sisebenzisa kuphela isithethi esisebenza rhoqo esinokukhupha isandi esiphezulu, esiphakathi, esiphantsi kunye nezinye iifrequencies zesandi. Nangona ibizwa ngokuba yifrequencies epheleleyo, ayinakugubungela zonke iibhendi zefrequencies, ifrequencies epheleleyo ibhekisa kuluhlu olubanzi lweefrequencies kunye nobubanzi begubungelo. Isithethi esisebenza ngexesha elipheleleyo Izinga lokudibanisa isithethi liphezulu, isigaba sichanekile, isandi sebhendi nganye yefrequencies sihlala sihambelana, kwaye izinga lokuphambuka kweendlebe liphantsi. Ngokukodwa, ukusebenza kwenxalenye yefrequencies ephakathi kugqwesile, kwaye isandi esikhutshwa ngabantu sikwifriquensi ephakathi, ngoko ke ilizwi lomntu ligcwele kwaye lendalo. Ke ngoko, isithethi esisebenza ngexesha elipheleleyo sisetyenziswa kakhulu kwiaudio yeTV (soundbar), enokuphucula nokuphucula imiphumo yesandi yeeTV.
