Mu rwego rw'amajwi, frequency yerekeza ku ijwi cyangwa ijwi ry'ijwi, ubusanzwe rivugwa muri Hertz (Hz). Frequency igena niba ijwi ari bass, hagati, cyangwa hejuru. Dore zimwe mu ntera z'amajwi asanzwe hamwe n'ikoreshwa ryazo:
1. Ingano ya bass: 20 Hz -250 Hz: Iyi ni intera ya bass, ikunze gutunganywa n'indangururamajwi ya bass. Iyi frequencies itanga ingaruka zikomeye za bass, zikwiriye igice cya bass cy'umuziki n'ingaruka nkeya nko guturika muri filime.
2. Intera yo hagati: 250 Hz -2000 Hz: Uru rwego rurimo intera nyamukuru y'imivugire y'abantu kandi ni na rwo rugaragara hagati y'amajwi y'ibicurangisho byinshi. Amajwi menshi n'ibicurangisho bya muzika biri muri urwo rwego mu bijyanye n'ijwi.
3. Ijwi rirenga: 2000 Hz -20000 Hz: Ijwi rirenga rirenga rikubiyemo ahantu harenga rirenga rishobora kubonwa n'abantu bumva. Iri jwi rirenga rikubiyemo ibikoresho byinshi birenga rirenga, nk'amajwi arenga rirenga ya violon na piano, ndetse n'amajwi y'abantu arambuye.
Muri sisitemu y'amajwi, byaba byiza ko amajwi atandukanye akoreshwa mu buryo buringaniye kugira ngo hamenyekane neza kandi ko ubuziranenge bw'amajwi burushaho kuba bwiza. Kubwibyo, sisitemu zimwe na zimwe z'amajwi zikoresha uburyo bwo kuringaniza ijwi kugira ngo zihindure ijwi ku buryo butandukanye kugira ngo zigere ku ngaruka z'amajwi zifuzwa. Ni ngombwa kumenya ko uburyo ugutwi kw'umuntu gushobora kumva amajwi atandukanye buratandukanye, ari nayo mpamvu sisitemu z'amajwi zikunze kuba zigomba kuringaniza ingano zitandukanye z'amajwi kugira ngo zikore ubunararibonye bwo kumva busanzwe kandi bunoze.
Ingufu zihabwa agaciro ni iki??
Ingufu z’urusaku zigaragazwa n’ubushobozi sisitemu ishobora gutanga mu buryo buhamye mu gihe ikora neza. Ni ikimenyetso cy’ingenzi cy’imikorere ya sisitemu, gifasha abakoresha gusobanukirwa uburyo sisitemu y’amajwi ikoreshwa n’ingano n’ingaruka ishobora gutanga mu gihe ikoreshwa mu buryo busanzwe.
Ingufu zigenwa akenshi zigaragazwa muri watts (w), bigaragaza urwego rw'ingufu sisitemu ishobora gutanga buri gihe nta gushyuha cyane cyangwa kwangiza. Agaciro k'ingufu gagenwa gashobora kuba agaciro kari munsi y'imitwaro itandukanye (nk'ama-ohm 8, ama-ohm 4), kuko imitwaro itandukanye igira ingaruka ku bushobozi bw'ingufu zisohoka.
Icyitonderwa ni uko imbaraga zigenwe zigomba gutandukanywa n'imbaraga zigenwe. Imbaraga zigenwe ni imbaraga ntarengwa sisitemu ishobora kwihanganira mu gihe gito, akenshi zikoreshwa mu guhangana n'amajwi ashyushye cyangwa amajwi arenga. Ariko, imbaraga zigenwe zibanda cyane ku mikorere irambye mu gihe kirekire.
Mu guhitamo sisitemu y'amajwi, ni ngombwa gusobanukirwa imbaraga zigenwe kuko zishobora kugufasha kumenya niba sisitemu y'amajwi ijyanye n'ibyo ukeneye. Niba imbaraga zigenwe z'isitemu y'amajwi ziri hasi ugereranyije n'urwego rusabwa, bishobora gutera kwangirika, kwangirika, ndetse no kwangiza. Ku rundi ruhande, niba imbaraga zigenwe z'isitemu y'amajwi ziri hejuru cyane ugereranyije n'urwego rusabwa, zishobora gupfusha ubusa ingufu n'amafaranga.
