Ngokuqhelekileyo kwindawo yomsitho, ukuba abasebenzi abakuloo ndawo abayiphathi kakuhle, imakrofoni iya kwenza isandi esirhabaxa xa ikufuphi nesithethi.Esi sandi sirhabaxa sibizwa ngokuba “kukubhomboloza”, okanye “inzuzo yokuphendula”.Le nkqubo ibangelwa ngumqondiso we-microphone wokungena ngokugqithisileyo, ephazamisa isandi esikhutshwayo kwaye ibangele ukukhala.

Ingxelo ye-Acoustic yinto engaqhelekanga edla ngokwenzeka kwiinkqubo zokuqinisa isandi (PA).Yingxaki ekhethekileyo ye-acoustic yeenkqubo zokuqinisa isandi.Kunokuthiwa kuyingozi ekuveliseni isandi.Abantu ababandakanyeka kumsindo wobuchwephesha, ngakumbi abo bachwetheza ukuqinisa isandi kwindawo, bakuthiyile ngokwenene ukubhomboloza kwesithethi, kuba ingxaki ebangelwa kukubhomboloza ayinasiphelo.Uninzi lwabasebenzi beaudio abaziingcali baphantse bagqogqa iingqondo zabo ukuze baphelise.Nangona kunjalo, kusenzima ukuphelisa ngokupheleleyo ukubhomboloza.Ukukhala kwengxelo ye-acoustic yinto yokubhomboloza ebangelwa yinxalenye yamandla esandi athunyelwa kwi-microphone ngokusasazwa kwesandi.Kwimeko ebalulekileyo apho kungabikho ukukhala, ithoni yokukhala iya kuvela.Ngeli xesha, ngokuqhelekileyo kuqwalaselwa ukuba kukho isenzeko sokubhomboloza.Emva kokuthomalalisa i-6dB, ichazwa njengokuba kungekho nto yakukhalayo eyenzekayo.

Xa i-microphone isetyenziselwa ukuthabatha isandi kwinkqubo yokuqinisa isandi, Ngenxa yokuba akunakwenzeka ukuthatha imilinganiselo yokuhlukanisa isandi phakathi kwendawo yokuthatha imakrofoni kunye nommandla wokudlala wesithethi.Isandi esivela kwisithethi sinokudlula ngokulula kwisithuba siye kwimakrofoni kwaye sibangele ukubhomboloza.Ngokuqhelekileyo, kuphela inkqubo yokuqinisa isandi enengxaki yokukhala, kwaye akukho mqathango wokubhomboloza konke konke kwinkqubo yokurekhoda kunye nokubuyisela.Ngokomzekelo, kukho kuphela izithethi zokubeka iliso kwinkqubo yokurekhoda, indawo yokusetyenziswa kwe-microphone kwi-studio yokurekhoda kunye nommandla wokudlala wezithethi ze-monitor zodwa omnye komnye, kwaye akukho mqathango wempendulo yomsindo.Kwinkqubo yokuvelisa isandi sefilimu, ii-microphone ziphantse zingasetyenziswa, nokuba Xa usebenzisa imakrofoni, iphinda isetyenziswe kwi-pickup yezwi esondeleyo kwigumbi lokubonisa.Isithethi soqikelelo sikude kumbhobho, ngoko ke akukho sizathu sokubhomboloza.

Izizathu ezinokwenzeka zokulila:

1. Sebenzisa i-microphone kunye nezithethi ngaxeshanye;

2. Isandi esisuka kwisithethi sinokudluliselwa kwi-microphone ngokusebenzisa isithuba;

3. Amandla esandi akhutshwa sisithethi makhulu ngokwaneleyo, kwaye uvelwano lwe-pickup ye-microphone iphezulu ngokwaneleyo.

Nje ukuba kwenzeke isenzeko sokubhomboloza, umthamo we-microphone awukwazi ukulungiswa kakhulu.Ukukhala kuya kuba kubi kakhulu emva kokuba kuvuliwe, okuya kubangela iziphumo ezimbi kakhulu ekusebenzeni okuphilayo, okanye isenzeko sokukhala kwesandi senzeka emva kokuba imakrofoni ivulwe ngokuvakalayo (oko kukuthi, xa imakrofoni ivuliwe. isandi se-microphone kwindawo ebalulekileyo yokubhomboloza), isandi sinomqondo wokubuyisela, otshabalalisa umgangatho wesandi;Kwiimeko ezinzima, isithethi okanye i-amplifier yamandla iya kutshiswa ngenxa yomqondiso ogqithisileyo, okwenza ukuba ukusebenza kungakwazi ukuqhubeka ngokuqhelekileyo, kubangela ilahleko enkulu yezoqoqosho kunye nokulahlekelwa kwegama.Ngokwembono yenqanaba lengozi yesandi, ukuthi cwaka kunye nokubhomboloza zezona ngozi zinkulu, ngoko ke injineli yesithethi kufuneka ithathe eyona nto inokwenzeka ukunqanda isenzeko sokubhomboloza ukuze kuqinisekiswe inkqubela phambili yesiqhelo yokomelezwa kwesandi kwindawo.

Iindlela zokuthintela ngempumelelo ukukhala:

Gcina i-microphone kude nezithethi;

Ukunciphisa umthamo we-microphone;

Sebenzisa iimpawu zokukhomba izithethi kunye ne-microphone ukuphepha iindawo zabo zokukhomba;

Sebenzisa i-frequency shifter;

Sebenzisa isilinganisi kunye nesicinezeli sempendulo;

Sebenzisa izithethi kunye nesandisi-lizwi ngokufanelekileyo.

Luxanduva lwabasebenzi abavakalayo ukulwa ngokungenasiphelo ngokubhomboloza kwesithethi.Ngophuhliso oluqhubekayo lwetekhnoloji yesandi, kuya kubakho iindlela ezininzi zokuphelisa kunye nokucinezela ukukhala.Nangona kunjalo, ukuthetha ngokwethiyori, Asiyonyani kakhulu inkqubo yokuqinisa isandi ukuphelisa isenzeko sokubhomboloza konke konke, , ngoko sinokuthatha amanyathelo ayimfuneko kuphela ukuphepha ukukhala kwindlela eqhelekileyo yokusetyenziswa.
