Ngokuvamile endaweni yomcimbi, uma izisebenzi zasendaweni zingawuphathi kahle, umbhobho uyokhipha umsindo onzima lapho useduze nesikhulumi.Lo msindo onokhahlo ubizwa ngokuthi “ukuhewula”, noma “ukuzuza impendulo”.Le nqubo ingenxa yesignali yokufaka yemakrofoni eyeqile, ehlanekezela umsindo okhishiwe futhi ibangele ukuhhewula.

Impendulo ye-Acoustic yinto engavamile evame ukwenzeka ezinhlelweni zokuqinisa umsindo (PA).Kuyinkinga eyingqayizivele ye-acoustic yezinhlelo zokuqinisa umsindo.Kungashiwo ukuthi kuyingozi ekukhiqizeni umsindo.Abantu abenza umsindo okhokhelwayo, ikakhulukazi labo abasebenza ngokukhethekile ekuqiniseni umsindo endaweni, bayakuzonda ngempela ukuklewula kwesipikha, ngoba inkinga ebangelwa ukuhhewula ayipheli.Iningi labasebenzi bomsindo abangochwepheshe bacishe bahlukumeza ubuchopho babo ukuze bakuqede.Nokho, kusengenzeka ukuqeda ngokuphelele ukuhhewula.Ukukhala kwempendulo ye-acoustic kuyinto ehewulayo ebangelwa ingxenye yamandla omsindo edluliselwa kumakrofoni ngokudluliswa komsindo.Esimeni esibucayi lapho kungekho khona ukukhala, kuzovela ithoni yokukhala.Ngalesi sikhathi, ngokuvamile kubhekwa ukuthi kukhona isenzakalo sokuhewula.Ngemuva kokuncishiswa kwe-6dB, kuchazwa ngokuthi akukho mkhuba wokukhala owenzekayo.

Uma i-microphone isetshenziselwa ukuthatha umsindo ohlelweni lokuqinisa umsindo, Ngoba akunakwenzeka ukuthatha izinyathelo zokuhlukanisa umsindo phakathi kwendawo yokuthatha imakrofoni nendawo yokudlala yesipikha.Umsindo ovela esipikheni ungadlula kalula esikhaleni uye kumakrofoni futhi ubangele ukuhhewula.Ngokuvamile, uhlelo lokuqinisa umsindo kuphela olunenkinga yokuhhewula, futhi asikho isimo sokuhhewula nhlobo ohlelweni lokurekhoda nokubuyisela.Isibonelo, kukhona izikhulumi zokuqapha kuphela ohlelweni lokurekhoda, indawo yokusetshenziswa kwemakrofoni ku-studio yokuqopha kanye nendawo yokudlala yezikhulumi zokuqapha ihlukaniswe komunye nomunye, futhi asikho isimo sempendulo yomsindo.Ohlelweni lokukhiqiza umsindo wefilimu, imibhobho cishe ayisetshenziswa, ngisho noma Uma usebenzisa imakrofoni, iphinde isetshenziselwe ukuvala izwi eliseduze ekamelweni lokubonisa.Isipikha se-projection sikude nombhobho, ngakho-ke akwenzeki ukuhhewula.

Izizathu ezingenzeka zokukhala:

1. Sebenzisa umbhobho nezipikha ngesikhathi esisodwa;

2. Umsindo ovela esipikheni ungadluliselwa kumbhobho ngokusebenzisa isikhala;

3. Amandla omsindo akhishwa yisipika makhulu ngokwanele, futhi ukuzwela kwe-pickup kombhobho kuphezulu ngokwanele.

Uma kwenzeka into ekhalayo, ivolumu yombhobho ayikwazi ukulungiswa kakhulu.Ukukhala kuzoba kubi kakhulu ngemuva kokuvulwa, okuzodala imiphumela emibi kakhulu ekusebenzeni okubukhoma, noma ukwenzeka kokukhala komsindo kwenzeka ngemuva kokuba imakrofoni ivulwe kakhulu (okungukuthi, uma imakrofoni ivuliwe. umsindo we-microphone endaweni ebalulekile yokukhala), umsindo unomqondo wokuphindaphinda, obhubhisa ikhwalithi yomsindo;Ezimweni ezimbi kakhulu, isipikha noma isikhulisi samandla sizoshiswa ngenxa yesiginali eyeqile, okwenza ukusebenza kungakwazi ukuqhubeka ngendlela evamile, okubangela ukulahlekelwa okukhulu komnotho kanye nokulahlekelwa isithunzi.Ngokombono weleveli yengozi yomsindo, ukuthula nokuhhewula kuyizingozi ezinkulu, ngakho unjiniyela wesipikha kufanele athathe ithuba elikhulu lokugwema ukukhala komsindo ukuze aqinisekise ukuqhubeka okuvamile kokuqiniswa komsindo kusayithi.

Izindlela zokugwema ngempumelelo ukukhala:

Gcina imakrofoni kude nezipikha;

Yehlisa ivolumu yemakrofoni;

Sebenzisa izici zokukhomba zezikhulumi kanye nemakrofoni ukuze ugweme izindawo zazo ezikhombayo;

Sebenzisa i-frequency shifter;

Sebenzisa isilinganisi kanye nokucindezela impendulo;

Sebenzisa izipikha namakrofoni ngokunengqondo.

Kungumsebenzi wabasebenzi abanomsindo ukulwa ngokungagodli ngokuhhewula kwesipikha.Ngokuthuthuka okuqhubekayo kobuchwepheshe bomsindo, kuzoba nezindlela eziningi zokuqeda nokucindezela ukukhala.Nokho, uma sikhuluma ngokwethiyori, Akulona iqiniso kakhulu ukuthi uhlelo lokuqinisa umsindo luqede konke ukukhala, , ngakho-ke singakwazi ukuthatha izinyathelo ezidingekayo ukuze sigweme ukukhala ekusetshenzisweni kwesistimu evamile.
