Umsindo waseChina wenzelwe iminyaka engaphezu kwengu-20, futhi akukho okungekho okucacile kwekhwalithi yomsindo. Ngokuyisisekelo, kuya ngezindlebe zawo wonke umuntu, impendulo yabasebenzisi, nesiphetho sokugcina (izwi lomlomo) elifanekisela ikhwalithi yomsindo. Akunandaba noma ngabe umsindo ulalele umculo, ukucula i-karaoke, noma ukudansa, ikhwalithi yomsindo wayo incike kakhulu ezicini ezine:

1. Umthombo wesiginali

Umsebenzi womsebenzi ukukhulisa umthombo wesiginali weleveli obuthakathaka kusipika, bese imvamisa yokudlidliza yophiko lwesikhulumi esiSomlomo izokhipha imisindo yamafrikhwidi ahlukahlukene, okungukuthi, imvamisa ephezulu, ephakathi nendawo ephansi esiyizwayo. Umthombo unesisindo (ukuhlanekezela) noma ezinye izinto zesiginali zilahlekile ngemuva kokucindezelwa. Ngemuva kokukhuliswa yi-amplifier yamandla, le misindo izokwenziwa ngokwengeziwe futhi izingxenye ezingekho ngeke zikwazi ukudedelwa, ngakho-ke i-audical ntom osetshenziswayo lapho sihlola umsindo muhle.

2. Imishini uqobo

Ngamanye amagama, i-amplifier yamandla kufanele ibe nesilinganiso esiphakeme se-Signal-to-umsindo, impendulo yemvamisa ebanzi, nokuhlanekezela okuphansi. Imvamisa yamandla esebenzayo yesipika kufanele ibe ububanzi, futhi ijika lokuphendula imvamisa kufanele libe lifulethi. Ukuphendula imvamisa kwe-20hz-20khz kungashiwo ukuthi kuhle kakhulu. Okwamanje, akuvamile ukuthi aisikhulumisiUkufinyelela ku-20Hz-20Khz + 3% DB. Kunezikhulumi eziningi emakethe imvamisa ephezulu engafinyelela ku-30 ​​noma ngisho ne-40Khz. Lokhu kukhombisa ukuthi ikhwalithi yomsindo ihlala ithuthuka, kepha sibantu abajwayelekile. Kunzima ukwahlukanisa amasiginali ngenhla kwe-20KHZ endlebeni, ngakho-ke akudingekile ukuphishekela amafrikhwensi aphezulu e-Ultra-high esingakwazi. Ijika le-flat flart frectency litve likwazi ukukhiqiza kabusha umsindo woqobo ngokweqiniso, futhi amandla ancike ngosayizi wendawo esetshenzisiwe. , Ukulingana. Uma le ndawo incane kakhulu futhi amandla amakhulu kakhulu, ingcindezi yomsindo izobangela ukuboniswa okuningi kakhulu futhi yenze i-turtuctions ethe xaxa, uma kungenjalo ingcindezi yomsindo ngeke ilwanele. Amandla we-amplifier kufanele abe ngu-20% aphakeme ku-50% aphezulu kunamandla kaSomlomo ngokuqhathaniswa nokuqina kwe-bass futhi aqine, futhi amazinga aphakathi nendawo azohlulwa, futhi ingcindezi yomsindo ngeke ihlungwe kalula.

3. Umsebenzisi uqobo

Abanye abantu bathenge ama-stereos for izimpahla, abanye bathokozise umculo, kanti okunye ukukhombisa. Kalula nje, uma umuntu engakwazi ngisho nokuhlukanisa imisindo ephezulu nephansi, angazwa yini ikhwalithi yomsindo omuhle? Ngaphezu kokukwazi ukulalela, abanye abantu badinga ukukwazi ukuyisebenzisa. Ngemuva kokuba abanye abantu befake izikhulumi zabo, uchwepheshe wokufaka azokhuluma ngomphumela. Umphumela uba ukuthi ngolunye usuku umuntu onelukuluku lokuhambisa ezinye izinduku, futhi wonke umuntu angacabanga umphumela. Lokhu akunjalo. Kuyadingeka ukuqonda ukuthi ubuchwepheshe bunjani, nje lapho sishayela, okungenani kufanele siqonde imisebenzi yokushintshwa okuhlukahlukene, izinkinobho, kanye namafindo ukuze sinikeze ukudla okugcwele ekusebenzeni nasekufezeni le moto.

4. Sebenzisa imvelo

Wonke umuntu uyazi ukuthi uma kungekho ndawo engekho egumbini elingenalutho, i-echo izwakala kakhulu lapho ushaya ushaya ukhuluma. Lokhu kungenxa yokuthi azikho izinto ezithinta umsindo ezinhlangothini eziyisithupha zekamelo noma umsindo awumuzwa ngokwanele, futhi umsindo uboniswa. Umsindo uyafana. Uma ukuvalwa komsindo kungalungile, umsindo ngeke ube mubi, ikakhulukazi uma umsindo uphakeme, uzobe udaka futhi unokhahlo. Vele, abanye abantu bathi akunakwenzeka ukusetha igumbi lokuhlolwa kwezimali ochwepheshe ekhaya. Imali encane ingakwenza kahle. Isibonelo: Hambisa isithombe esifekethisiwe odongeni olukhulu oluhle futhi luzwakala, lulengise amakhethini kakotini amakhulu emafasiteleni engilazi, noma ubeke amakhaphethi emhlabathini, noma ngabe kungukhaphethi wokuhlobisa phakathi komhlaba. Umphumela uzomangaza. Uma ufuna ukwenza kangcono, ungalengisa imihlobiso ethambile futhi engabushelelezi odongeni noma ophahleni, okuyinto enhle futhi yehlisa ukuboniswa.
