Ibintu Vy'Ivyiyumviro Igihe Guhitamwo Amafaranga y'Ukwumviriza Ku bantu bakuze

Kumva bifasha ku isoko bigabanywamwo ubwoko bwinshi: ubwoko bw'agasanduku, inyuma{- ubwoko bw'isanduku, mu - ubwoko bw'ubwoko bw'umugende w'ugutwi, n'ubwoko bw'umugende w'ugutwi.
1. Inzoka - uburyo bwo kwumva na zo nyene zitwa umufuko- ubwoko canke umufuko- ubwoko. Ni nini gatoyi kuruta isandugu y’imikino. Umubiri n’amatelefone y’ugutwi bifatanye n’intsinga. Iyo iriko irakoreshwa, amatelefone yo mu matwi yinjizwa mu mugende w’ugutwi kw’inyuma maze ako gasandugu kashirwa mu mufuko w’igikiriza. Inyungu zayo ntizigira ingorane nyinshi, ububasha bwinshi, bworoshe gukoresha, bworoshe guhindura, igihe kirekire, n’igiciro gito, ivyo bikaba bishobora gushitsa ivyo abantu bafise ubupfapfa bukomeye. Ariko rero, ubwo bwoko bw’agasanduku k’ugutahura buzotuma haba urusaku rw’ugucika intege iyo rushizwe mu mufuko, rugire ico rukoze ku bijanye n’ivangura ry’ururimi. Biragaragara cane iyo umuntu yambara, rero rimwe na rimwe birababaza.
2. Ukuboneka kw'inyuma- Igikoresho co kwumva co kwumva ni 3{5}}4 cm ndende igoramye. Ishirwa inyuma y’ivyo bikoresho, ikarungika iryo jwi mu mugende w’ugutwi biciye mu ruganda rw’ugutwi rumeze nk’ihembe n’uruzitiro rw’ipulasitike. Inyungu zayo si amawaya, ubunini buto, buhishijwe cane, bukeyi, kandi bushobora gukoreshwa n’umurongo w’induction kugira ngo wongere igikorwa co kwumviriza telefone. Ivyago ni uko bisabwa igipfukisho kidasanzwe c’ugutwi, ivyo bikaba bitoroshe gukoreshwa mu ntango kandi ko bitoroshe guhindura.
3. Muri - ibikoresho vyo kwumva n’ibikoresho vyo kwumva ni utuntu dutoduto two kwumva n’ivyiza vyo kuba muto, wihishije, wire- ataco ukeneye gukora, ingaruka nziza zo kwumva, kandi zishobora gutuma umuntu yumva neza; ariko ntibibereye guhindura kandi bizimvye, kandi bikwiye gutunganirizwa mu buryo bubereye hakurikijwe umugende w’ugutwi n’umwotsi w’umuntu wese. Kubera ububasha bwayo buke, ni vyiza gusa ku buhungiro buringaniye kandi ntibubereye kugira ngo umuntu agire ububabare bukomeye kandi bukomeye cane.
Igihe uhitamwo igikoresho co kwumva, ni vyiza kuja mu bitaro kugira ngo ubone isuzuma ry’ugutega amatwi, ukoreshe ubuhinga bwo gupima umuyagankuba n’ibindi bikoresho kugira ngo usuzume neza urugero rw’ubugoyagoye, hanyuma uhitemwo ikintu co kwumva. Iyo ata bitaro bifise ibintu bihuye n’ivyo mu karere, urugero rw’ugutakaza ugutahura n’uguhitamwo ububasha bwo kwumva bishobora kugereranywa hakurikijwe ibipimo vy’amajambo. Nk’akarorero, abantu badashobora kwumva ivyo bavuga batakaje 30 gushika kuri 40 decibel, kandi abantu badashobora kwumva amajwi yoroshe batakaza ama decibel 40 gushika kuri 50. Muri iki gihe, ni vyiza kugura hasi- n’ibindi bikoresho vy’ubuhinga. abantu badashobora kwumva imvugo isanzwe batakaje ama decibels nka 50 gushika kuri 60, kandi abantu badashobora kwumva bavuga n’ijwi rirenga, baratakaje 60 na 70 decibel. Bishobora guhitamwo - Inguvu n'ubushobozi bwinshi- ibikoresho vyo kwumva; abantu badashobora kwumva induru zivuga cane zifise ugutahura 70 gushika kuri 80, kugira ngo bashobore guhitamwo {- n’ibikoresho vy’ububasha vy’inguvu nyinshi; abantu badashobora kwumva buzuye - Ivugurura ry'induru bafise ugutakaza ugutahura kw'abantu nka 80 gushika kuri 90 decibel canke hejuru, kugira ngo bashobore guhitamwo - Inkomezi n'inyongera - ibikoresho vy'ububasha.
