Amaherezo wararonse urutonde rukora. Ivyo gufata amenyo biranyobwa buri gitondo, amenyo y’ikinyoma arasukurwa imbere yo kuryama, kandi umucungerezi wawe w’ijoro arasukurwa cane buri ndwi. Hanyuma ukanda buto y’umuriro iri ku gikoresho cawe co gusukura, maze ijwi ry’ijwi rirenga-rica mu cumba. Mu bwogero, birashoboka. Mu cumba co kuraramwo, aho ushaka kuyikoresha imbere yo kuryama canke ubwo nyene umaze kuvyuka, ni deal-breaker. Kumbure warabonye spec " Munsi canke ingana na 45dB" canke "ultra-quiet" ku mapaji y'ibicuruzwa - ariko uwo mubare mu vy'ukuri usobanura iki, kandi woba utekanye bihagije ku cumba co kuraramwo?
Kubera iki ibikoresho vy'isuku vy'imigenzo bivuga cane
Ikibazo c’urusaku si ukugenzura umugambi; ni ingaruka zitaziguye z’ingene ugusukura kw’amajwi bikora.
Fizike y'urusaku rw'amajwi - Aho ijwi riva
Ivyo gusukura bikoresheje amajwigutwara igikoresho gihindura umuyagankuba ku mirongo iri hagati ya 40.000 na 53.000 Hz - iri hejuru cane y’ugutwi kw’umuntu. Ivyo wumva si umupfunda w’amajwi ubwawo ahubwo ni ingaruka mbi z’igikorwa cawo. Inkomoko nyamukuru ni cavitation: ibibumbano bitobito birahingura kandi bikasenyuka bikomeye mu mazi yo gusukura, igisenyuka cose kigatuma haba aka "pop" gatoyi k'umurongo wagutse gafatanya kakagira ijwi ry'ugusenyuka ridahera. Igitera kabiri ni ijwi ry’ivyuma - itangi, igipfukisho, n’ishingiro binyiganyiga mu buryo bw’impuhwe n’ico gikoresho, bikahindura ico gikoresho kikaba akavugishwa gatoyi. Ivyuma bihenda cane biratuma ingorane zirushirizaho kubera ibikoresho bihindura amakuru bifise agaciro gatoyi, inkuta z’ibidengeri zitoyi, kandi nta n’ivyo guhagarika ukunyiganyiga, ni co gituma urusaku ruca mu cumba.
Kubera iki gukoresha icumba co kuraramwo bisaba urugero rutandukanye
Icumba co kuraramwo ni co kibanza kibi kuruta ibindi vyose gishoboka c’amajwi ku gikoresho gifise urusaku. Mu bisanzwe ni ntoyi cane, ifise ibintu bikomeye nk’ibitanda vyo mw’ijoro be n’ivyirore bigaragaza aho gufata ijwi. Nta mazi canke umuyaga wo gukuraho urusaku kugira ngo upfuke urusaku, kandi icumba gikoreshwa neza na neza igihe uguceceka ari ikintu gihambaye cane - mu gitondo ca kare no ku mugoroba. Igikoresho co gusukura gisoma ngo "cemewe" mu gikoni gishobora kwumva kivyinjiramwo iruhande y'igitanda, cane cane ku bantu basinzira bike. Gusukura ivyumba vy’uburaro bikeneye umugwi w’ibikoresho vy’ishimikiro bitekanye, atari ikigereranyo ciza gatoyi c’umubumbe umwe.
Ivyo Biri munsi canke bingana na 45dB Mu vy'ukuri Bisobanura - Igikoresho co Gutangura
"Urusaku ruri munsi ya decibels 45" ruvuga nk'urw'ubuhinga, ariko urugero rwa decibels rworoshe gutahura iyo umaze kumenya ingingo nkeyi z'ishingiro - kandi mbere biroroshe gutahura iyo ubonye itandukaniro ry'imibare mikeyi igira.
Urugero rwa Decibel mu majambo ya misi yose
Urugero rwa decibel (dB) ni urugero rwa logarithme: iyo umuntu yiyongera 10 dB, bigereranya ko ijwi ryiyongera incuro cumi kandi ribonwa ko ryiyongera incuro zibiri. Ijwi ry’ugusemerera ripima nk’amadB 30. Ico kibanza c’ibitabu gicereje cicara hafi y’amajwi 40 dB. Ikiyago gisanzwe gikora 60 gushika kuri 65 dB. Igikoresho gipimwa ku rugero rwa A-weighted scale (dBA), kigaragaza ubushobozi bwo kwumva umuntu, igikoresho gipima 45 dB kivuga cane nk’ijwi ry’ibiro vy’abantu bicereje - rigaragara mu gihe c’uguceceka, ariko ryoroshe kwirengagiza iyo rikoreshwa mu buryo busanzwe. Ivyuma vyinshi vy’ugusukura bikoresha amajwi menshi bitanga amajwi 55 gushika kuri 65 dB, bikagwa mu rusaku rw’ikiyago-ruzokwumvikana ata gukeka mu cumba co kuraramwo.
Uko urusaku rw'isuku ry'amajwi rwo hejuru rupimwa
Abahinguzi bakunda gupima umuvuduko w'ijwi ku ntambwe idahinduka - mu bisanzwe metero imwe - uvuye ku gikoresho mu cumba giteye akaruru mu gihe c'ugukora kw'imiterere -. Ni co gituma umubare w'urupapuro rwa spec-ushobora kwumva uri hasi y'ivyo ubona iyo uri hafi: ugutwi kwawe akenshi kuba kure y'imetero imwe, kandi icumba co kuraramwo gikomeye-gifise inkuta congeramwo ivyiyumviro ibidukikije vy'ingero bikuraho. Fata igiharuro nk'urutonde rwizewe rw'uguceceka hagati y'ibigereranyo, mu gihe witega ko ingero z'isi nyakuri-zigenda hejuru cane. Uwo murongo ni wo utuma guhitamwo igikoresho co gusukura gifise 35 dB aho guhitamwo 45 dB bihambaye - 10 dB z'inyongera z'umwanya wo mu mutwe zituma igikorwa nyaco kiguma kiri munsi y'urugero rw'"ikiyago" mbere no mu cumba kigaragaza.
Ikibazo c'urusaku mu buzima nyakuri
Umubare wa decibel ni ikintu kitaboneka gushika uwushize ku ikarita ku bihe vy’ukuri igihe umusuku akora vy’ukuri. Ivyabaye ku musi ku musi vyerekana igituma igitigiri c’urusaku ari co kintu kimwe gihambaye kuruta ibindi vyose ku bakoresha ivyumba vyo kuraramwo.
Gusukura mw'ijoro no guhungabanya itiro
Ivyo umuntu akora cane mu cumba co kuraramwo ni ugusukura ikintu co kurinda ijoro, ikintu co gufata, canke ikintu co gutuma umuntu aryama imbere y’uko aryama - kandi ishirahamwe mpuzamakungu ryitaho amagara y’abantu risaba ko urusaku rudahera mu gihe umuntu asinziriye ruguma munsi ya 30 dB kugira ngo umuntu aruhuke ataco ahagaritse umutima. Igikoresho co gusukura gisanzwe kivuga ku 55 gushika kuri 60 dB cicara hejuru cane y’uwo murongo kandi kigatanga ubwoko bw’uguboroga kw’incuro nyinshi ubwonko bufata nk’ugukangura aho gufata nk’uguboroga kw’inyuma. Ubushakashatsi ku bijanye n’urusaku n’ubwubatsi bw’itiro bwerekana ko mbere n’ibintu bitera amajwi bivyuka bishobora gucapura itiro ryinshi kandi bikagabanya ubushobozi bwaryo bwo gusubizaho. Ku babiranye, ivyo bitera ingorane incuro zibiri: uwudakoresha igikoresho co gusukura arahungabanywa n’urusaku ata nyungu bavamwo.
Ivyumba bitobito biratuma ingorane zikomera
Ivyumba vyo kuraramwo, amazu manini manini be n’ibiro vyo mu nzu ntibibabarira. Ivyumba bikomeye, ameza yo iruhande y’igitanda be n’inkuta zitapfutse biragaragaza imipfunda y’amajwi, kandi icumba gitoyi bisigura ko ico gikoresho cicara hafi y’amatwi yawe. Ico gikoresho nyene co gusukura kivuza induru ata wukibona mu bwogero bufise amabuye y’agaciro, kirashobora kuganza icumba gitoyi co kuraramwo. Inyungu ni igikoresho ca kabiri co gutera ijwi - kirungika inyungu ku meza y’ijoro gihindura ibikoresho bihinduka igikoresho co gutera ijwi, bigatuma urusaku rusa n’urwo hejuru kuruta uko igipimo ca decibel kivyerekana. Ibirenge vy’i silikoni, umusego w’imbere woroshe, n’uguhagarika ukunyiganyiga kw’imbere vyose biragabanya izo nguvu zirungikwa, ni co gituma ibikoresho vy’agaciro vy’agaciro vyitaho ibirenze gusa igihinduzi.
Ivyo ushobora kurondera mu gikoresho co gusukura gikoresheje amajwi y’imbere mu gitereko
Si ikirego cose "ultra-quiet" kirokoka guhura n'icumba co kuraramwo nyaco. Ivyagezwe vy'ukuri bitandukanya ibikoresho vy'ukuri bicereje n'urusaku rwo kwamamaza.
Urusaku ruri munsi ya 45 dB - Ivyiza ni 35 dB
Umubare w’umutwe w’inkuru ukwiye kuba akayunguruzo kawe ka mbere. Ikintu cose gifise igipimo ca 45 dB canke kiri munsi yaco kizokwemerwa mu bwogero kandi kizokoreshwa mu cumba co kuraramwo; dB ishira ibikorwa ku rugero rw'ububiko bw'ibitabo, isiga umwanya mwiza hejuru y'urugero rw'itiro -n'inyuma y'aho ivyiyumviro vy'isi vy'ukuri-vyongeweko. Nk’akarorero, igikoresho co gusukura c’amajwi y’imbere mu gitereko citwa GoldRosa US600 gishobora gusubirwamwo, gifise ubushobozi bwa 35 dB - bucereje ku buryo benshi mu bakoresha bacidondora nk’ijwi ry’ijwi ry’ijwi ry’ijwi ry’ijwi ry’ijwi ry’ijwi ry’ijwi, ari ryo tandukaniro hagati y’igikoresho ukoresha ijoro ryose n’ico ubika mu kabati.
Ivyerekeye Igishushanyo Bigabanya Urusaku
Gukora mu gacerere ni injeniyeri, ntivyivugwa. Rondera ibintu bitatu. Ica mbere, uburyo bw’umuhinduzi n’umushoferi: incuro y’ugukubura (nk’iya 47–52 kHz) ihinduka gatoyi mu gihe c’ugukora igabanya ijwi ry’ivyuma rituma umuntu aboroga mu buryo budahinduka-. Ubwa kabiri, uguhagarika ijwi: itangi ry’ibipande bibiri-, igishingo gifise uburemere, canke ibikoresho bikingira ijwi-bibuza igipfukisho gukora nk’ijwi. Ica gatatu, igikorwa gipfutse: igipfukisho c’umuyagankuba gifata neza kirimwo ijwi ry’ugusenyuka. US600 ihuriza hamwe imiterere y’ibipande bibiri-n’igipfukisho c’umuyagankuba n’umubumbe w’umushoferi w’agaciro, ivuga ku vyo vyose bitatu bitera urusaku.
Inguvu za Bateri n'Ihuza ry'Ukugendera Ivyategekanijwe-
Hariho isano ridatomoye cane hagati y’inkomoko y’amashanyarazi n’urusaku: ibikoresho vy’isuku bikoreshwa na bateri-bikoreshwa cane cane mu gukoresha mu rugo bitekanye kandi bishobora gutwara, mu gihe ibikoresho bifise imigozi bifise amapompo akomeye n’ibihindura amashanyarazi vyubatswe kugira ngo bikoreshe mu mavuriro no mu mahugurwa. Igikoresho co gusukura gishobora gusubirwamwo umuriro gifise bateri ibiri -core n’ubwoko-C bwo gushaja - nka US600, gitanga inzinguzingu zigera ku cumi zo gusukura ku gushaja - kigaragaza igikoresho cakozwe ku bijanye n’ivyumba vyo kuraramwo. Gukoresha umugozi na vyo nyene birakuraho ijwi ry’umuyagankuba kandi bikaba bitanga umwidegemvyo wo gushiramwo, ku buryo uwusukura ashobora kuba aho hose bibangamira bikeyi.
Uko wokoresha igikoresho co gusukura mu cumba cawe
Mbere n’igikoresho co gusukura gicereje vy’ukuri kirakora neza cane iyo ugishizeho n’ibigirankana. Amahitamwo makeyi yo gushiramwo n'igihe arafunga ikinogo hagati y'imibare y'impapuro n'ivyo kubaho -mu gacerere.
Impanuro zo gushiramwo n'igihe
Shira igikoresho co gusukura ku kintu gipfutse - igitambaro gipfutse canke igitambaro co mu silikoni - kugira ngo kinywere ukunyiganyiga imbere y’uko gishika ku bikoresho vyo mu nzu. Uyishire n’imiburiburi metero imwe uvuye ku gitanda, vyiza ni ukuyishira inyuma y’igitanda co kuryamako iraba kure y’umusego wawe. Niwiruke inzinguzingu ndende ku murango igihe urusaku rwo mu karere rupfuka ijwi ry’agahomerabunwa, kandi ubike inzinguzingu ngufi z’iminota 3-kugeza kuri-5 ku rutonde rw’igihe co kuryama. Igihe kiboneka n’ikigaragaza - US600 irimwo igisomwa c’amatara - bigufasha gutangura uruziga no kumenya neza igihe ruzohera.
Guhindura Gusukura Mu Gacerere Akamenyero Ramba
Inyungu nyayo y’igikoresho co gusukura 35 dB ni inyifato. Iyo igikoresho kitagaragara, iminota itanu-isuku ry’ijoro ry’igikoresho cawe co kugufata canke co kurinda ijoro rihagarika kwumva ko ari igikorwa c’urugo maze kikaba igice c’urutonde rwa misi yose - kandi gusukura ubudasiba biratuma ibikoresho vyo mu kanwa bimara igihe kirekire. Hitamwo ikigereranyo gifise igikoresho c’ubwenge c’i Hall gica igikoresho co gukingira ubumara bwa UVC iyo igipfukisho kigutse, kugira ngo kibe gitekanye ku meza y’ijoro mbere n’aho umuryango uri hafi. Hagati y’ugukora kw’ijwi ry’agahomerabunwa, ivy’umutekano, n’ugushaja kwa USB-C bikorana n’igishaja kiri iruhande y’igitanda cawe, igikoresho co gusukura c’amajwi y’imbere mu gacerere gica kiba intambwe yoroshe kuruta izindi zo ku mugoroba wawe.
