I-stereophony |

izincwadi. - umsindo wendawo, kusukela kusiGreki. ama-stereo - okuzungezile, indawo kanye ne-ponn - umsindo

Indlela yocingo nokusakaza, kanye nokurekhoda komsindo nokukhiqizwa kwayo, lapho uhlamvu lomsindo lugcinwa khona, okubonisa ukuhlelwa kwendawo yokubola. imithombo yomsindo nokunyakaza kwayo. Umuntu uhlulela indawo yemithombo yomsindo emkhathini ngokuphathelene nomehluko womthelela wazo ezindlebeni ezingakwesokudla nezingakwesokunxele; ku-physiology ibizwa ngokuthi. umphumela we-binaural. Kuye nge-engeli eyakhiwe phakathi kwegagasi elingaphambili lomsindo nekhanda lomlaleli, diff. ukuzwakala ngezindlebe ezingakwesokudla nezingakwesokunxele kunqunywa kokubili umehluko wesigaba samagagasi omsindo acatshangwayo kanye nokuba buthaka komsindo ngenxa yokuvinjelwa kwayo ingxenye yikhanda lomlaleli. Kucingo kanye ne-radiotelephony, umphumela we-stereo ufinyelelwa ngokusetshenziswa kwamashaneli amabili eziteshini ezimbili ezihlukene. imakrofoni (ebekwe ebangeni elithile ukusuka kwenye) kanye nokudlalwa kwayo kusetshenziswa ama-otd amabili. izingcingo noma izipikha ezimbili (izipikha ezizwakalayo). Ukurekhoda umsindo we-stereo kusetshenziswa imibhobho emibili etholakala kude ne-otd. ama-amplifier namashaneli amabili okurekhoda ahambisanayo. Ku-stereogram, amasiginali womabili agxilile emseleni ofanayo. Umsiki werekhoda ye-stereo oscillates ngaphansi kwamandla kazibuthe amabili noma i-piezoelectric eqondiswe ngokuhlobene nge-engeli engu-90°. Ukukhiqizwa kabusha komsindo kwenziwa idivayisi ekhethekile ye-adaptha kanye nama-otd amabili. ama-amplifiers anezipikha ezifakiwe kuye ngosayizi wegumbi kanye nebanga labalaleli. Kumamuvi, ukuqoshwa kwe-stereo kwenziwa ngokubona. indlela emaphethelweni efilimu ngezindlela zobubanzi obuguquguqukayo noma ukuminyana kwesiginali ephrintiwe kumathrekhi amabili ahambisana nemakrofoni amabili. Ukurekhodwa kwe-stereo yamagnetic kwenziwa kusetshenziswa imibhobho emibili enezikhala ehlukene. ama-amplifiers namakhanda okurekhoda kazibuthe kumathrekhi amabili efilimu, nokudlala kwe-stereo - usebenzisa i-otd. ama-amplifiers avela kumakhanda kazibuthe amabili nama-acoustic amabili. izipikha ezifakwe ebangeni olifunayo. Okwe-estr. i-stereo kwesinye isikhathi kusetshenziswa amashaneli amathathu ahlukene akhulisa umbhobho kanye nawokukhiqiza umsindo; amakholomu amathathu e-acoustic atholakala ngaphesheya kobubanzi besiteji.

Ukuqoshwa komsindo we-stereo kusondeza umbono womculo kulokho okwenziwa ngokuqondile. ngilalele ukusebenza kwakhe ku-conc. ihholo. Izinga lokubaluleka elizuzwe ngosizo lwayo lwe-stereophonic. umphumela uncike ekubeni umsebenzi othile womlando othile. inkathi, ukuya ohlotsheni oluthile, kanye nokusuka kusitayela salo. izici nokusebenza. ukwakheka. Ngakho, emakhulwini 18-19. abaqambi balwela ubunye obukhulu kakhulu bokuwohloka komsindo. amaqembu e-orchestra, abonakala ekubekweni kwabadlali ("izihlalo" ze-orchestra). Ukuqoshwa kwesiteshi esisodwa kwemikhiqizo enjalo. nakakhulu kwandisa ubunye bomsindo we-ork. amaqembu, nesitiriyo sigcina izikhala zabo zangempela, ukuhlakazeka. Kodwa-ke, lapho uqopha umculo, lapho izikhala nemiphumela isetshenziswa ngandlela thize (lokhu kusebenza ikakhulukazi ekudaleni umculo wekhulu lama-20; bheka umculo we-Spatial), indima ye-S. iyanda. Kusukela kuma-70s. Ngekhulu lama-20, ngaphezu kokujwayelekile kwe-stereophonic, iziteshi ezine, ukuqoshwa komsindo we-quadraphonic nakho kuyasetshenziswa, ngokusikwa kwemakrofoni emine (ngesikhathi sokurekhoda) kanye ne-acoustic emine. amakholomu (ngesikhathi sokudlala) atholakala emakhoneni esikwele noma unxande, phakathi nendawo okukhona umenzi (abadlali) futhi, ngokufanele, umlaleli. Kwamanye amazwe (eJalimane, eGreat Britain, e-USA, njll.) kwaqala i-quadraphonic. ukusakazwa komsakazo kukhiqizwa i-quadraphonic. izamukeli zomsakazo, izikhulisamazwi, iziqophamazwi, izidlali zikagesi namarekhodi egilamafoni. S. ngokuma okuqondile komsindo akukatholi ukusebenza. izicelo.
