Ijwi ritaziguye ni ijwi riva mu ndangururamajwi rigagera ku muntu uyumva. Ikiranga cyaryo nyamukuru ni uko ijwi ritaziguye, ni ukuvuga ubwoko bw'ijwi riva mu ndangururamajwi, umuntu uyumva yumva ubwoko bw'ijwi, kandi ijwi ritaziguye ntirinyura mu cyumba gishushanyijeho urukuta, hasi no hejuru, nta nenge ziterwa n'urumuri rw'ibikoresho byo gushushanya imbere, kandi ntirigira ingaruka ku buryo ijwi riva mu nzu rikoreshwa. Kubwibyo, ubwiza bw'ijwi burahamye kandi ubwiza bw'ijwi ni bwinshi. Ihame ry'ingenzi cyane mu miterere y'indangururamajwi yo mu cyumba ni ugukoresha neza ijwi riva mu ndangururamajwi mu gice cyo kumva no kugenzura ijwi riva mu buryo bushoboka bwose. Mu cyumba, uburyo bwo kumenya niba agace ko kumva kabona ijwi riva mu ndangururamajwi zose ni bworoshye cyane, muri rusange hakoreshejwe uburyo bwo kureba. Mu gace ko kumva, niba umuntu uri mu gace ko kumva ashobora kubona indangururamajwi zose, kandi akaba aherereye mu gace aho indangururamajwi zose zinyura mu majwi, ijwi riva mu ndangururamajwi rishobora kuboneka.

Mu bihe bisanzwe, gufunga indangururamajwi ni igisubizo cyiza ku ijwi ritaziguye mu cyumba, ariko rimwe na rimwe bitewe n'intera nto n'umwanya muto mu cyumba, indangururamajwi ishobora kugengwa n'amategeko amwe n'amwe. Niba bishoboka, ni byiza kumanika indangururamajwi.

Inguni yo kwerekana ihoni y'abavuga benshi iri muri dogere 60, inguni yo kwerekana itambitse ni nini, icyerekezo cy'inguni ihagaze ni gito, niba agace k'amajwi katari mu nguni yo kwerekana ihoni, ijwi ry'ihoni ntirishobora kuboneka, bityo iyo abavuga bashyizwe mu buryo butambitse, umurongo wa tweeter ugomba kuba uhuye n'urwego rw'amatwi y'uwumva. Iyo umuvuga amajwi amanitswe, ikintu cy'ingenzi ni uguhindura inguni yo kuzenguruka y'abavuga amajwi kugira ngo hirindwe ingaruka ku buryo bwo kumva ijwi rya treble.

Iyo umuvugizi arimo aracuranga, uko umuvugizi yegera umuvugizi, ni ko ijwi ritaziguye riba rinini, kandi uko ijwi rigaragara riba rito, ni ko ijwi ritaziguye riba rito.
