makalata. - phokoso la malo, kuchokera ku Greek. stereo - kuzungulira, malo ndi ponn - phokoso

Njira ya telephony ndi kuwulutsa, komanso kujambula kwa mawu ndi kutulutsa kwake, komwe khalidwe la phokoso limasungidwa, kusonyeza makonzedwe a malo a decomp. magwero omveka ndi kayendedwe kawo. Munthu amaweruza malo magwero zomveka mu danga mogwirizana ndi kusiyana mmene amakhudzira kumanja ndi kumanzere makutu; mu physiology amatchedwa. Binaural effect. Malingana ndi mbali yomwe imapangidwira pakati pa phokoso lakutsogolo kwa phokoso ndi mutu wa omvera, diff. kumveka ndi makutu a kumanja ndi kumanzere kumatsimikiziridwa ndi kusiyana kwa gawo la mafunde omwe amamveka komanso kufowoka kwa phokoso chifukwa cha kutetezedwa kwake pang'ono ndi mutu wa omvera. Mu telephony ndi radiotelephony, mphamvu ya stereo imatheka pogwiritsa ntchito njira ziwiri zotumizira kuchokera ku njira ziwiri zosiyana. maikolofoni (oyikidwa pamtunda wina kuchokera kwa wina ndi mnzake) ndikusewera kwake pogwiritsa ntchito ma otd awiri. mafoni kapena oyankhula awiri (acoustic speaker). Pazojambula za stereo zimagwiritsidwa ntchito maikolofoni awiri omwe ali patali kuchokera ku otd. amplifiers ndi njira ziwiri zojambulira zofananira. Mu stereogram, ma siginecha onse amakhazikika panjira yomweyo. Wodula wa chojambulira cha stereo amazungulira motengera mphamvu ziwiri za maginito kapena piezoelectric zolozerana wina ndi mnzake pakona ya 90 °. Kutulutsa mawu kumayendetsedwa ndi chida chapadera cha adapter ndi two otd. amplifiers okhala ndi okamba oikidwa kutengera kukula kwa chipindacho komanso mtunda wa omvera. Kwa makanema, kujambula kwa stereo kumachitika mwa mawonekedwe. Njira m'mphepete mwa filimuyo ndi njira zamitundu yosiyanasiyana m'lifupi kapena kachulukidwe ka siginecha yosindikizidwa pama mayendedwe awiri ofanana ndi maikolofoni awiri. Kujambulira kwa maginito kwa sitiriyo kumapangidwa pogwiritsa ntchito maikolofoni awiri otalikirana ndi osiyana. amplifiers ndi mitu yojambulira maginito panjira ziwiri za filimuyo, ndi kusewera kwa stereo - pogwiritsa ntchito otd. ma amplifiers ochokera ku mitu iwiri ya maginito ndi ma acoustic awiri. okamba anaika pa mtunda ankafuna. Za est. stereo nthawi zina atatu osiyana maikolofoni okulitsa ndi kutulutsa mawu njira amagwiritsidwa ntchito; mizati atatu lamayimbidwe zili kudutsa m'lifupi mwa siteji.

Kujambula kwa mawu a stereo kumabweretsa malingaliro a nyimbo pafupi ndi zomwe zimachitika mwachindunji. kumvetsera machitidwe ake mu conc. holo. Mlingo wa kufunikira komwe kunachitika ndi thandizo lake stereophonic. zotsatira zimadalira kukhala wa ntchito yopatsidwa ku mbiri inayake. nthawi, ku mtundu wina, komanso kuchokera kumayendedwe ake. mawonekedwe ndi magwiridwe antchito. kupanga. Choncho, mu 18-19 zaka. olemba nyimbo ankalimbikira kugwirizana kwakukulu kothekera kwa kuwola kwa mawu. magulu a oimba, zomwe zinasonyezedwa ndi kuyika kwa oimba ("mipando" ya oimba). Kujambulitsa panjira imodzi pazinthu zotere. kwambiri kumawonjezera umodzi wa phokoso la ork. magulu, ndipo stereo imasunga malo awo enieni, kubalalitsidwa. Komabe, pojambula nyimbo, momwe malo ndi zotsatira zimagwiritsidwa ntchito mwanjira ina (izi zimagwira ntchito makamaka pakupanga nyimbo za m'zaka za zana la 20; onani nyimbo za Spatial), udindo wa S. ukuwonjezeka. Kuyambira m'ma 70s. M'zaka za zana la 20, kuwonjezera pa stereophonic wamba, njira zinayi, zojambula za quadraphonic zimagwiritsidwanso ntchito, ndi kudula kwa maikolofoni anayi (panthawi yojambula) ndi ma acoustic anayi. zipilala (pamasewera) zili m'makona a lalikulu kapena rectangle, pakati pa amene ndi woimba (osewera) ndipo, moyenerera, womvera. Kunja (Germany, Great Britain, USA, etc.) anayamba quadraphonic. mawayilesi amapangidwa quadraphonic. zolandilira wailesi, zokulirakulira, zojambulira matepi, zosewerera zamagetsi ndi ma galamafoni.
