Umsindo waseTshayina uphuhliswe ngaphezu kweminyaka engama-20, kwaye awukabikho umgangatho ocacileyo womgangatho wesandi.Ngokusisiseko, kuxhomekeke kwiindlebe zomntu wonke, impendulo yabasebenzisi, kunye nesiphelo sokugqibela (ilizwi lomlomo) elimele umgangatho wesandi.Nokuba iaudio imamele umculo, ukucula ikaraoke, okanye ukudanisa, umgangatho wesandi sayo uxhomekeke ikakhulu kwizinto ezine:

1. Umthombo womqondiso

Umsebenzi womsebenzi kukukhulisa nokukhupha umgangatho obuthathaka womthombo wesignali kwisithethi, kwaye ke ukungcangcazela kwamaxesha eyunithi yesithethi kwisithethi kuya kukhupha izandi zamaza ahlukeneyo, oko kukuthi, aphezulu, aphakathi, namaza aphantsi. yiva.Umthombo unengxolo (ukuphazamiseka) okanye amanye amalungu omqondiso alahlekileyo emva koxinzelelo.Emva kokwandiswa yi-amplifier yamandla, ezi ngxolo ziya kwandiswa ngakumbi kwaye amacandelo alahlekileyo akayi kukwazi ukukhululwa, ngoko ke umthombo wesandi osetyenziswayo xa sivavanya isandi kulungile Okubi kubalulekile.

2. Isixhobo ngokwaso

Ngamanye amazwi, i-amplifier yamandla kufuneka ibe ne-signal-to-noise ratio, i-frequency ebanzi esebenzayo, kunye nokuphazamiseka okuphantsi.Umbane osebenza rhoqo wesithethi kufuneka ube banzi, kwaye ijiko lokuphendula kufuneka libe mcaba.Ukuphendula rhoqo kwe-20Hz-20KHz kunokuthiwa kuhle kakhulu.Okwangoku, kunqabile ukuba aisithethiukufikelela ku-20Hz–20KHz+3%dB.Kukho izithethi ezininzi kwimarike ukuba i-frequency ephezulu inokufikelela kwi-30 okanye i-40KHz.Oku kubonisa ukuba umgangatho wesandi uhlala uphucula, kodwa singabantu abaqhelekileyo.Kunzima ukwahlula imiqondiso engaphezulu kwe-20KHz endlebeni, ngoko akuyomfuneko ukulandela amaza omoya aphezulu esingevayo.Kuphela igophe lokuphendula lefrikhwensi ethe tyaba inokuvelisa kwakhona isandi sokuqala ngokwenyani, kwaye amandla axhomekeke kubungakanani bendawo esetyenzisiweyo., Ukuba ngokomlinganiselo.Ukuba indawo incinci kwaye amandla makhulu kakhulu, uxinzelelo lwesandi luya kubangela ukubonakaliswa okuninzi kwaye lenze ithoni ibe ne-turbid, ngaphandle koko uxinzelelo lwesandi luya kunganelanga.Amandla e-amplifier kufuneka abe ngama-20% ukuya kuma-50% aphezulu ngaphezu kwamandla esithethi kwi-impedance ehambelanayo ukwenzela ukuba i-bass ibe yomelele kwaye yomelele, amanqanaba aphakathi kunye nethoni ephezulu aya kucaca ngakumbi, kwaye uxinzelelo lwesandi aluyi kuba njalo. igqwethekile ngokulula.

3. Umsebenzisi ngokwakhe

Abanye abantu bathenga ii-stereo zefenitshala, abanye baxabisa umculo, kwaye omnye kukubonisa.Ngamafutshane, ukuba umntu akakwazi ukwahlula isandi esiphakamileyo nesisezantsi, ngaba unokusiva eso sisandi esilungileyo?Ukongezelela ekukwazini ukuphulaphula, abanye abantu kufuneka bakwazi ukuyisebenzisa.Emva kokuba abanye abantu befake izithethi zabo, igcisa lokufakela liya kuthetha nje ngesiphumo.Isiphumo kukuba ngenye imini umntu othile unomdla wokuhambisa amaqhina, kwaye wonke umntu unokuwuthelekelela umphumo.Oku akunjalo.Kubalulekile ukuqonda ukuba yeyiphi iteknoloji, njengaxa siqhuba, kufuneka ubuncinane siqonde imisebenzi yokutshintsha ezahlukeneyo, amaqhosha, kunye namaqhosha ukuze anike umdlalo opheleleyo ekusebenzeni kunye nokhuseleko lwale moto.

4. Sebenzisa okusingqongileyo

Wonke umntu uyazi ukuba xa kungekho mntu kwigumbi elingenanto, i-echo ikhwaza ngakumbi xa uqhwaba kwaye uthetha.Oku kubangelwa kukuba akukho nto ifunxa isandi kumacala amathandathu egumbi okanye isandi asitsalwanga ngokwaneleyo, yaye isandi siyavela.Isandi siyafana.Ukuba ukufunxa isandi akulungile, isandi siya kuba mnandi, ngakumbi ukuba isandi siphezulu, siya kuba nodaka kwaye sibe lukhuni.Kakade ke, abanye abantu bathi akunakwenzeka ukuseta igumbi lovavanyo lobuchule ekhaya.Imali encinci inokuyenza kakuhle.Umzekelo: xhoma umfanekiso ohonjisiweyo eludongeni olukhulu oluhle nolutsala isandi, xhoma ikhethini zomqhaphu ezingqindilili kwiifestile zeglasi, ubeke iikhaphethi phantsi, nokuba yikhaphethi yokuhombisa embindini womhlaba.Isiphumo siya kumangalisa.Ukuba ufuna ukwenza ngcono, unokuxhoma imihlobiso ethambileyo nengagudiyo eludongeni okanye kwisilingi, entle kwaye inciphisa ukubonakaliswa.
