Ngaba uyazi ukuba zeziphi iintlobo zeenkqubo ezenza isandi sezithethi zakho? Ngezantsi uzakufunda yonke into ofuna ukuyifumana malunga ne-monophonic, stereophonic, multichannel kunye nomsindo ojikelezayo.
Isandi seMonophonic
Isandi seMonophonic senziwe ngumzila omnye okanye isithethi kwaye saziwa ngokuba yiMoorural or High-Fidelity sound. Isandi seMonophonic satshintshwa nguStereo okanye isandi seStereophonic ngawo-1960.
Isandi seStereophonic
Isandi seStereo okanye iStereophonic senziwe ngamashaneli ezimbini ezizodwa ezivakalayo okanye izithethi kwaye zinikeza ingqiqo yesikhokelo kuba izandi zinokuvela kwiindlela ezihlukeneyo. Ixesha elithi stereophonic lithathwe kwigama lesiGrike elithi stereos- lithetha intsingiselo, kunye nefowuni- esithetha isandi. Isandi seStereo sinokuvelisa izandi kunye nomculo kwizikhokelo ezahlukeneyo okanye izikhundla ngendlela esiva ngayo izinto ngokwemvelo. Isandi seStereo yindlela eqhelekileyo yokuvelisa izandi.
Isandi seMixchannel Surround Sound
Isandi seMicchannel, esaziwayo njengengxolo ejikelezileyo, senziwa ngamancinci angama-4 ukuya kwi sixhenxe ezizimeleyo ezilalelwayo okanye izithethi ezibekwa phambi nangemva komphulaphuli ojikeleze umphulaphuli ngesandi. Isandi seMixchannel sinokuzonwabisa kwiiDVD umculo, ii-DVD kunye namaCD. Isandi seMixchannel saqala ngo-1970 kunye nokufakwa kwesandi se-Quadraphonic, saziwa nangokuthi yiQuad. Isandi seMixchannel saziwa ngokuba yi-5.1, 6.1 okanye 7.1 isandi sesiteshi.
5.1, 6.1 kunye no-7.1 Isondo sesandi
- Isandi sesiteshi se-5.1 yinkomfa efanelekileyo yeshishini yee-movie kunye nomculo ngeendlela ezinhlanu zesandi kunye nesithandathu se-subwoofer yesitishi (esibizwa ngokuba ngumzila-enye itya) esetyenziselwa imifanekiso yecala ekhethekileyo kunye nomculo womculo. Inkqubo yesiteshi se-5.1 iqukethe isithethi seesiteti se stereo, isithethi sesiteshi seziko elibekwe phakathi kwezithethi ze-stereo kunye nezithethi ezimbini ezizungezile ezikhoyo emva komphulaphuli. Isandi sesiteshi se-5.1 sitholakala kwiidiskrikhi ze-DVD kunye nemiziki kunye namanye amaCD.
- Isandi sesiteshi se-6.1 isandi sokwenza isandi kwisandi sesi-5.1 kunye nesiseko esongezelelweyo isithethi esisandi esiphezulu phakathi kwezithethi ezimbini ezizungeze ngqo emva komphulaphuli. Isandi sesiteshi se-6.1 sivelisa amava aphilileyo ajikelezayo.
- Isandi sesiteshi se-7.1 sisinye isandi sokwenza isandi se-channel yesibini kunye nezithethi ezimbini ezongeziweyo zecala ezijikelezayo ezikumacala omgangatho wokuhlala. Isandi sesiteshi se-7.1 sisetyenziselwa ukukhutshwa kwesandi esikhulu kunye nokubeka izandi ezichanekileyo.
