Dore ibanga ryo kongera umuvuduko w'amajwi inshuro ebyiri!

Mu isi y'amajwi y'umwuga, gushaka ireme ry'amajwi no kuyasakaza ntagereranywa. Imwe mu ntambwe zikomeye mu ikoranabuhanga ryo kongera amajwi ni iterambere rya sisitemu zo gushyira amajwi mu byiciro bitandukanye. Izi sisitemu zabaye amahitamo y'ibitaramo by'umwuga kuva ku bitaramo kugeza ku bikorwa by'ibigo, kandi ku bw'impamvu ifatika. Muri iyi nkuru, turasuzuma icyatuma sisitemu zo gushyira amajwi mu byiciro bitandukanye zikundwa cyane mu majwi y'umwuga kandi tugahishura amabanga y'ubushobozi bwazo bwo gukuba kabiri urugero rw'umuvuduko w'amajwi.

Gusobanukirwa ikoranabuhanga rya Line Array

Ishingiro ry'umurongo ni urukurikirane rw'indangururamajwi zitondetse mu buryo buhagaze. Ubu buryo butuma amajwi akwirakwira neza kurusha imiterere isanzwe y'indangururamajwi. Imiterere y'umurongo iwufasha kwerekana amajwi mu ntera ndende ariko igakomeza kugaragara neza no ku buryo buhamye. Ibi ni ingenzi cyane cyane ahantu hanini, kuko bakeneye amajwi kugera mu mfuruka zose nta gutakaza ubuziranenge bw'amajwi.

Ikintu cy'ingenzi ku mikorere myiza y'abavuga kuri 'line array' ni ubushobozi bwabo bwo gukoresha ihame ryo kubangamira umuraba. Iyo abavuga kuri 'line array' benshi bashyizwe hamwe bahagaze, bakorana kugira ngo bakore 'consistent wavefront'. Ibi bivuze ko amajwi ava kuri buri muvuga yiyongeranya, bigatuma habaho urwego rwo hejuru rw'umuvuduko w'amajwi (SPL) mu ntera. Iki kintu gikunze kwitwa "coupling", kandi ni uko guhuza kwemerera 'line arrays' gutanga amajwi akomeye nta kongera cyane.

Ibyiza bya Sisitemu ya Line Array

1. Kwagura uburyo bwo guhamagara: Imwe mu mpamvu nyamukuru zikoreshwa mu gukoresha sisitemu z'umurongo mu buryo bw'umwuga ni ubushobozi bwazo bwo gutanga uburyo bwo guhamagara bungana ahantu hanini. Imiterere y'indangururamajwi gakondo ikunze gutuma amajwi akwirakwira mu buryo budahuye, bigatuma ijwi rirenga mu bice bimwe na bimwe kandi ijwi rikagabanuka mu bindi bice. Imirongo ishobora guhindurwa hakurikijwe amajwi yihariye y'aho bavugira, bigatuma buri wese mu bari aho yumva uburyo bwo kumva buri gihe.

2. Kugabanya ibitekerezo: Gusubiza ni ikibazo gikunze kugaragara mu kongera ijwi mu buryo bw'amajwi, cyane cyane iyo hakoreshejwe mikoro. Imirongo ishobora gushyirwa mu buryo bugabanya amahirwe yo gusubiza. Mu kuyobora amajwi kure ya mikoro n'ibindi bikoresho byoroheje, abahanga mu by'amajwi bashobora kugera ku nyungu nyinshi mbere yo gusubiza, bigatuma habaho imikorere ihamye.

3. Gupima: Sisitemu z'umurongo zikoreshwa cyane kandi zikwiriye uburyo butandukanye bwo kuzikoresha. Yaba ari akabyiniro gato cyangwa sitade nini, umurongo ukoreshwa ushobora gushyirwaho kugira ngo uhuze n'ibyo ukeneye byihariye by'igikorwa. Ku bahanga mu by'amajwi bakunze gukora ahantu hatandukanye, ubu buryo bworoshye ni inyungu ikomeye.

4. Ubwiza: Uretse ibyiza bya tekiniki, imirongo ifite isura nziza kandi igezweho. Ibi ni ingenzi cyane cyane ku birori byo ku rwego rwo hejuru, aho kwerekana amashusho ari ingenzi kimwe n'ubwiza bw'amajwi. Imiterere mito y'imirongo ituma ihuzwa neza n'imiterere y'urubyiniro, bigatuma ibitekerezo by'abareba bihora byibanda ku gitaramo.

Kugwiza kabiri urugero rw'umuvuduko w'ijwi

Noneho, reka twirebere amabanga y'uburyo imirongo ikuba kabiri urugero rw'umuvuduko w'amajwi. Igitekerezo cy'urwego rw'umuvuduko w'amajwi ni ingenzi kugira ngo dusobanukirwe ubukana bw'ijwi bugaragara. Ripimirwa muri desibeli (dB), kandi impinduka ya dB 10 igaragaza ukwiyongera inshuro 10 k'ubukana bw'amajwi. Kubwibyo, kugira ngo ubukana bw'ijwi bugaragare kabiri, hakenewe kwiyongeraho hafi dB 10.

Imirongo ihuza umurongo igera kuri iki gikorwa gitangaje binyuze mu miterere yayo yihariye n'imiterere yayo. Iyo indangururamajwi zishyizwe hamwe zihagaze, zigira umurongo ugororotse utuma amajwi anyura kure kandi mu buryo bukomeye. Ibi bigira akamaro cyane cyane ahantu hanini hakenewe gukwirakwira kure. Mu gukoresha indangururamajwi nyinshi mu murongo umwe, abahanga mu by'amajwi bashobora kongera neza urugero rw'umuvuduko w'amajwi (SPL) batiriwe bakenera ingufu z'inyongera.

Byongeye kandi, ubushobozi bwo kugenzura uburyo amajwi akwirakwira mu buryo buhagaze butuma abari aho bashyirwa neza. Ibi bivuze ko amajwi ashobora kugera ku bari aho mu buryo butaziguye mu gihe agabanya urumuri ruturutse ku nkuta no ku gisenge rushobora kwangiza amajwi. Umusaruro ni ijwi risobanutse kandi rikomeye ryuzura aho hantu ribera nta nkomyi.

Muri make
Muri rusange, sisitemu z'amajwi zahinduye uburyo imikorere y'umwuga ikorwa. Ubushobozi bwabo bwo gutanga amakuru angana, kugabanya ibitekerezo, no guhuza n'ingano zitandukanye z'aho hantu biba bituma baba igikoresho cy'ingenzi ku bahanga mu by'amajwi. Ibanga ry'intsinzi yabo riri mu miterere yabo yihariye, ikubye kabiri urugero rw'umuvuduko w'amajwi binyuze mu kubangamira umuvuduko w'amajwi no kwerekana amajwi neza.

Uko ikoranabuhanga rikomeza gutera imbere, nta gushidikanya ko imirongo izajya iyobora mu gutanga ibisubizo by'amajwi by'umwuga. Ku muntu wese ukora ibitaramo bya Live, gusobanukirwa ibyiza n'amahame imikorere ya sisitemu y'imirongo ni ingenzi kugira ngo habeho ubunararibonye bwiza bw'amajwi. Waba uri injeniyeri w'amajwi, umuhanzi cyangwa utegura ibirori, gukoresha ikoranabuhanga ry'imirongo bishobora kuzamura imikorere yawe, bikagufasha kumva neza buri noti kandi buri kanya gatangaje kakamenyekana.
