Umsindo waseShayina uthuthukiswe iminyaka engaphezu kwengu-20, futhi akukabikho izinga elicacile lekhwalithi yomsindo.Ngokuyisisekelo, kuncike ezindlebeni zawo wonke umuntu, impendulo yabasebenzisi, nesiphetho sokugcina (izwi lomlomo) elimele ikhwalithi yomsindo.Noma ngabe umsindo ulalele umculo, i-karaoke eculayo, noma uyadansa, ikhwalithi yomsindo wayo incike kakhulu ezintweni ezine:

1. Umthombo wesiginali

Umsebenzi womsebenzi uwukukhulisa nokukhipha umthombo wesignali wezinga elibuthakathaka kusipika, bese kuthi imvamisa yokudlidliza yeyunithi yesipika esipikheni ikhiphe imisindo yamafrikhwensi ahlukahlukene, okungukuthi, amaza aphezulu, amaphakathi, naphansi. yizwa.Umthombo unomsindo (ukuhlanekezela) noma ezinye izingxenye zesignali ziyalahleka ngemva kokucindezelwa.Ngemva kokukhulisa amandla ngesikhulisi samandla, le misindo izokhuliswa kakhulu futhi izingxenye ezingekho ngeke zikwazi ukukhululwa, ngakho umthombo womsindo osetshenziswa lapho sihlola umsindo ukuthi muhle Okubi kubalulekile.

2. Imishini ngokwayo

Ngamanye amazwi, isikhulisi samandla kufanele sibe nesilinganiso esiphezulu sesignali-kuya-kumsindo, impendulo ebanzi esebenzayo yemvamisa, kanye nokuhlanekezela okuphansi.Ifrikhwensi yamandla esebenzayo yesipika kufanele ibe banzi, futhi ijika lokuphendula imvamisa kufanele libe isicaba.Ukusabela kwemvamisa okungu-20Hz-20KHz kungashiwo ukuthi kuhle kakhulu.Njengamanje, kuyivelakancane ukuthi aisikhulumiukufinyelela ku-20Hz–20KHz+3%dB.Kunezikhulumi eziningi emakethe ukuthi imvamisa ephezulu ingafinyelela ku-30 ​​noma ku-40KHz.Lokhu kubonisa ukuthi ikhwalithi yomsindo ithuthuka njalo, kodwa singabantu abavamile.Kunzima ukuhlukanisa amasignali angaphezu kuka-20KHz endlebeni, ngakho-ke akudingekile ukulandela amaza aphakeme kakhulu esingakwazi ukuwazwa.Ijika lempendulo yefrikhwensi eyisicaba kuphela engakhiqiza kabusha umsindo wangempela ngokwangempela, futhi amandla ancike kusayizi wendawo esetshenzisiwe., Ukuze kulingane.Uma indawo incane kakhulu futhi amandla emakhulu kakhulu, ukucindezela komsindo kuzobangela ukubonakaliswa okuningi futhi kwenza ithoni ibe ne-turbid, ngaphandle kwalokho ukucindezela komsindo ngeke kwanele.Amandla we-amplifier kufanele abe ngama-20% kuya ku-50% aphezulu kunamandla esipika ekufaniseni i-impedance ukuze i-bass iqine futhi ibe namandla, amazinga ethoni aphakathi nendawo aphezulu azocaca, futhi ukucindezela komsindo ngeke kube njalo. ihlanekezelwe kalula.

3. Umsebenzisi uqobo

Abanye abantu bathenga ama-stereo ukuze bathole impahla, abanye bawujabulela umculo, kanti omunye uwukubukisa.Kalula nje, uma umuntu engakwazi ngisho nokuhlukanisa imisindo ephakeme nephansi, ingabe angakwazi ukuzwa ukuthi iyiphi ikhwalithi yomsindo enhle?Ngaphezu kokukwazi ukulalela, abanye abantu kudingeka bakwazi ukukusebenzisa.Ngemuva kokuthi abanye abantu sebefake izipikha zabo, uchwepheshe wokufaka uzovele akhulume ngomphumela.Umphumela uba ukuthi ngolunye usuku othile unelukuluku lokuhambisa amanye amafindo, futhi wonke umuntu angawucabanga umphumela.Akunjalo.Kubalulekile ukuqonda ukuthi yibuphi ubuchwepheshe, njengalapho sishayela, kufanele okungenani siqonde imisebenzi yokushintshashintsha okuhlukahlukene, izinkinobho, nama-knob ukuze sinikeze ukudlala okugcwele ekusebenzeni nokuphepha kwale moto.

4. Sebenzisa indawo ezungezile

Wonke umuntu uyazi ukuthi uma kungekho muntu egumbini elingenalutho, i-echo iba phezulu kakhulu uma ushaya izandla futhi ukhuluma.Lokhu kungenxa yokuthi akukho lutho olumunca umsindo ezinhlangothini eziyisithupha zegumbi noma umsindo awumuncwe ngokwanele, futhi umsindo uyavela.Umsindo uyafana.Uma ukumuncwa komsindo kungalungile, umsindo uzobe ungajabulisi, ikakhulukazi uma umsindo uphezulu, uzoba onodaka futhi ube nokhahlo.Yiqiniso, abanye abantu bathi akunakwenzeka ukusetha ikamelo lokuhlola lochwepheshe ekhaya.Imali encane ingakwenza kahle.Isibonelo: lenga isithombe esifekethisiwe odongeni olukhulu oluhle futhi olumunca umsindo, lenga amakhethini kakotini aminyene emafasiteleni engilazi, futhi ubeke okhaphethi phansi, ngisho noma kuwukhaphethi wokuhlobisa phakathi nendawo.Umphumela uzomangaza.Uma ufuna ukwenza kangcono, ungalenga imihlobiso ethambile futhi engasheleli odongeni noma ophahleni, okuyinto enhle futhi enciphisa ukubonakaliswa.
