Ubushakashatsi bwa siyansi bwerekana ko ahantu heza ho guhurira hashobora kongera ituze ry'amarangamutima ku kigero cya 40% no kugira uruhare mu mibereho myiza ku kigero cya 35%.

Mu bigo byita ku bageze mu zabukuru, bikeneye kwitabwaho by’umwihariko, sisitemu y’amajwi ikozwe neza kandi ifite imiterere myiza irimo kuba igikoresho cy’ingenzi mu kunoza imibereho y’abageze mu zabukuru. Bitandukanye n’ahantu hasanzwe hakorerwa ubucuruzi, sisitemu y’amajwi mu bigo byita ku bageze mu zabukuru igomba kwita ku miterere y’umubiri n’ibyo abantu bakenera mu mutwe, ibi bikaba bisaba igishushanyo cyihariye cy’ibikoresho nk’ibyuma bitera inkunga (amplifier), poroseseri na mikoro.

Sisitemu y'amajwi yo mu bigo byita ku bageze mu za bukuru igomba kubanza gusuzuma imiterere y'amatwi y'abageze mu za bukuru. Bitewe n'ububabare bwo kutumva buterwa no gusaza, ubushobozi bwabo bwo kumva ibimenyetso bikoresha amajwi menshi buzagabanuka cyane. Muri iki gihe, hakenewe uburyo bwihariye bwo gusubiza amajwi kuri mashini itunganya amajwi, ibyo bigatuma imvugo irushaho kuba nziza binyuze mu buryo bw'ubwenge, mu gihe bigabanyije neza ibice bikomeye bikoresha amajwi menshi. Sisitemu yo gukuza amajwi ifite ubuziranenge buhanitse igomba kwemeza ko amajwi ari yoroshye kandi nubwo yacurangwa igihe kirekire, nta mananiza yo kumva.

Imiterere y'umuziki ucuranga inyuma ni ingenzi cyane mu bikorwa rusange. Ubushakashatsi bwagaragaje ko gucuranga umuziki ukwiye bishobora kongera ituze ry'amarangamutima y'abantu bakuze ku kigero cya 40%. Ibi bisaba ko icyuma gitunganya umuziki gihinduranya ubwoko bw'umuziki mu buryo bw'ubwenge hakurikijwe ibihe bitandukanye: gucuranga indirimbo zituje za mu gitondo kugira ngo zifashe kubyuka mu gitondo, gutegura indirimbo za zahabu zishyushye kugira ngo zigaruke mu bihe byiza nyuma ya saa sita, no gukoresha umuziki ufasha abantu gusinzira kugira ngo baruhuke nimugoroba. Ibi byose bisaba kugenzura neza ijwi n'ubwiza bw'amajwi binyuze muri sisitemu y'ubwenge yo gukuza amajwi.

Sisitemu ya mikoro ifite inshingano nyinshi mu bigo byita ku bageze mu za bukuru. Ku ruhande rumwe, igomba kwemeza ko ijwi ry'uwateguye ibirori rigera ku muntu wese ukuze, ibyo bikaba bisaba gukoresha mikoro zishobora gukumira urusaku rw'ibidukikije neza. Ku rundi ruhande, mikoro zikoresha insinga zishobora no gukoreshwa mu bikorwa by'imyidagaduro nka karaoke, guteza imbere imikoranire n'itumanaho hagati y'abageze mu za bukuru, ibyo bikaba bigira ingaruka zikomeye mu kongera uruhare rwabo mu mibanire.

Sisitemu yo guhamagara mu gihe cy’ubutabazi ni ingenzi mu buryo bw’amajwi mu bigo byita ku bageze mu za bukuru. Binyuze mu mikoro zitangwa mu byumba bitandukanye, abageze mu za bukuru bashobora gushaka ubufasha mbere na mbere iyo bahuye n’ibibazo by’ubutabazi. Ubu buryo bugomba guhuzwa neza n’ibyuma bitanga amplifiers na poroseseri kugira ngo amajwi y’inzogera abe menshi bihagije kugira ngo akure abantu kandi adakaye cyane ku buryo atatera ubwoba.

Muri make, sisitemu y'amajwi ishaje mu bigo byita ku bageze mu zabukuru ni igisubizo cyuzuye gihuza amajwi meza, kugenzura amplifier y'ubwenge, poroseseri y'umwuga, n'itumanaho risobanutse neza rya mikoro. Iyi sisitemu ntirema gusa ibidukikije byiza kandi bishimishije ku bageze mu zabukuru, ahubwo inatanga ihumure mu byiyumvo, iteza imbere imikoranire myiza, kandi irinda umutekano n'ubuzima binyuze mu majwi nk'uburyo bwo kuyakoresha. Muri iki gihe sosiyete ishaje cyane, gushora imari muri sisitemu y'amajwi ishaje ni ikintu cy'ingenzi ku bigo byita ku bageze mu zabukuru kugira ngo binoze urwego rwabyo rwa serivisi kandi bigaragaze ubuvuzi bwa kimuntu.
