Imvamisa endaweni yomcimbi, uma abasebenzi abasendaweni abayiphathi kahle, imakrofoni izokwenza umsindo onokhahlo lapho isondele kusipika. Lo msindo omubi ubizwa ngokuthi "ukugcotshwa", noma "ukuzuza impendulo". Le nqubo ingenxa yesiginali yokufaka yemakrofoni eyeqile, ehlanekezela umsindo okhishwe futhi ibangela ukukhala.

Impendulo ye-acoustic yinto engajwayelekile evame ukwenzeka ezinhlelweni zokuqinisa umsindo (PA). Kuyinkinga eyingqayizivele ye-acoustic yezinhlelo zokuqinisa umsindo. Kungashiwo ukuthi kulimaza ukuzala kabusha. Abantu ababandakanyeka ku-Audio ochwepheshe, ikakhulukazi labo abasebenza ngokuqinile ekuqinisweni komsindo obonakalayo, bangizonda ngempela isikhulumi, ngoba inkathazo ebangelwa amandla aphela. Iningi labasebenzi bomsindo abuchwepheshe bacishe baqoqa ubuchopho babo ukuze baliqede. Kodwa-ke, akunakwenzeka ukuqeda ngokuphelele ukukhala. I-Acoustic Foiceback Beling iyinto eshayayo ebangelwa yingxenye yamandla anomsindo adluliselwa kumakrofoni ngokuhanjiswa okuzwakalayo. Esimweni esibucayi lapho kungekho khona ukukhala, kuzovela ithoni yokukhala. Ngalesi sikhathi, ngokuvamile kubhekwa ukuthi kunento eshayayo. Ngemuva kokufakwa kwe-6DB, kuchazwa njengoba kungekho mkhuba wokukhala.

Lapho imakrofoni isetshenziselwa ukukhetha umsindo ohlelweni oluqiniswayo, ngoba akunakwenzeka ukuthatha izindlela zokuhlukaniswa ngomsindo phakathi kwendawo yokuthola imakrofoni nendawo yokudlala yesipika. Umsindo ovela esiSomlomo ungadlula kalula esikhaleni esiya kwimakrofoni futhi ubangele ukukhala. Ngokuvamile, uhlelo lokuqinisa umsindo kuphela olunenkinga yokukhala, futhi asikho isimo sokukhala nhlobo ezinhlelweni zokuqopha nokubuyiselwa. Isibonelo, kunezikhulumi zokuqapha kuphela ohlelweni lokurekhoda, indawo esetshenziswayo yemakrofoni esiteshini sokuqopha kanye nendawo yokudlala yezikhulumi zokuqapha isolated komunye nomunye, futhi akukho simo sempendulo enengqondo. Ehlelweni lokukhiqiza kabusha amafilimu, ama-microphones cishe awasetshenziswanga, noma ngabe lapho usebenzisa imakrofoni, futhi isetshenziselwa ukuvuselelwa kwezwi kwezwi egumbini lokuqagela. Isipika se-Projection sikude kakhulu nemakrofoni, ngakho-ke akukho malive.

Izizathu ezingaba khona zokukhala:

1. Sebenzisa imakrofoni nezikhulumi ngasikhathi sinye;

2. Umsindo ovela esiSomlomo angadluliselwa kumakrofoni esikhala;

3. Amandla azwakalayo akhishwe yisipika makhulu ngokwanele, futhi ukuzwela kwe-pickup yemakrofoni kuphezulu ngokwanele.

Lapho nje into eshayayo yenzeka, ivolumu yemakrofoni ayikwazi ukulungiswa kakhulu. Ukukhala kubucayi kakhulu ngemuva kokuthi kuvuliwe, okuzodala imiphumela emibi kakhulu ekusebenzeni okubukhoma, noma umdwebo wemakromoni wenzeka ngemuva kwemakrofoni), umsindo unomuzwa wokubuyela emuva, okubhubhisa ikhwalithi yomsindo; Ezimweni ezinzima, isikhulumi noma isikhuno se-amplifier sizoshiswa ngenxa yesiginali ngokweqile, okwenza ukusebenza kungakwazi ukuqhubeka ngokujwayelekile, kubangele ukulahleka okukhulu komnotho kanye nokulahleka kwedumela. Ngokombono wezinga lezengozi yomsindo, ukuthula kanye nokukhala kuyizingozi ezinkulu kakhulu, ngakho-ke unjiniyela wesipika kufanele athathe amathuba amakhulu okugwema inqubekela phambili evamile yokuqina komsindo we-On-Site.

Izindlela zokugwema ngempumelelo ukukhala:

Gcina imakrofoni kude nezikhulumi;

Yehlisa ivolumu yemakrofoni;

Sebenzisa izici ezikhomba izikhulumi kanye namamakrofoni ukugwema izindawo zabo ezikhomba;

Sebenzisa i-frequerch shifter;

Sebenzisa i-Equalizer kanye nempendulo ye-suppresser;

Sebenzisa izikhulumi kanye namamakrofoni ngokufanele.

Kungumsebenzi wabasebenzi abanomsindo ukulwa nokungachazi ngesipika. Ngokuthuthuka okuqhubekayo kobuchwepheshe bomsindo, kuzoba nezindlela eziningi neziningi zokuqeda nokucindezela ukukhala. Kodwa-ke, ukukhuluma ngokweqiniso, akunangqondo kakhulu ngohlelo lokuqinisa umsindo ukuqeda into elisandayo,, ngakho-ke singathatha kuphela izindlela ezidingekayo zokugwema ukukhala okujwayelekile kohlelo.
