Tus thawj coj hauv wireless headphones ntsuam xyuas: Sony WH-1000XM2
Roskachestvo ua ke nrog International Assembly of Consumer Testing Organizations (ICRT) kev tshawb fawb ntawm cov qauv headphone sib txawv los ntawm cov nqi sib txawv. Raws li cov txiaj ntsig ntawm txoj kev tshawb fawb, kev ntsuam xyuas ntawm cov khoom siv zoo tshaj plaws muaj rau cov neeg siv khoom Lavxias tau muab tso ua ke.
Nyob rau hauv tag nrho, cov kws txawj tau kawm 93 khub ntawm wired thiab 84 khub ntawm wireless headphones los ntawm ntau hom (cov kws tshaj lij studio qauv tsis tau sim). Tag nrho cov qauv raug kuaj ntawm cov tsis xws li qhov zoo ntawm lub suab teeb liab kis tau tus mob, lub durability ntawm lub mloog pob ntseg, functionality, suab zoo thiab yooj yim ntawm kev siv.
Qhov kev sim nws tus kheej tau ua nyob rau hauv ib lub chaw soj nstuam thoob ntiaj teb uas ua haujlwm raws li ISO 19025 tus qauv (tus qauv zoo tau txais los ntawm International Organization for Standardization).
Cov cuab yeej tshwj xeeb tau siv los ntsuas qhov tsis xws li qhov zoo ntawm lub suab teeb liab kis tau tus mob, lub zog ntawm lub mloog pob ntseg thiab lawv txoj haujlwm. Lub suab zoo thiab yooj yim ntawm lub cuab yeej tau sim los ntawm cov kws tshaj lij. Technology tsis muaj peev xwm ntawm qhov kev ntsuam xyuas zoo li no.
Nws yog qhov nthuav tias qee tus neeg tsim khoom ntawm lub mloog pob ntseg uas tsis yog kev tshaj lij qhia txog ntau yam kev tsim tawm ntau zaus, uas, thawj zaug, tsis yog ib txwm ua rau kev nkag siab, thiab qhov thib ob, feem ntau tsis muaj tseeb.
"Kev hnov lus ntawm tib neeg yog tsim los ntawm txoj hauv kev uas nws pom lub suab nrog qhov zaus ntawm kwv yees li 20 txog 20000 Hz. Txhua yam hauv qab 20Hz (infrasound) thiab txhua yam saum toj no 20000Hz (ultrasound) tsis pom los ntawm tib neeg pob ntseg. Yog li ntawd, nws tsis yog qhov tseeb heev thaum cov chaw tsim khoom ntawm tsev neeg (tsis yog tus kws tshaj lij) lub mloog pob ntseg sau rau hauv cov lus piav qhia uas lawv tsim cov zaus hauv thaj tsam ntawm 10 - 30000Hz. Tej zaum nws suav nrog cov neeg yuav khoom tsis yog hauv ntiaj teb keeb kwm xwb. Nyob rau hauv qhov tseeb, nws feem ntau hloov tawm hais tias cov yam ntxwv tshaj tawm nyob deb heev ntawm qhov tseeb, "said Daniil Meerson, tus thawj coj suab paj nruag ntawm lub xov tooj cua "Moscow Speaks".
Nws kuj ntseeg tias thaum xaiv lub mloog pob ntseg koj yuav tsum tau kuaj xyuas lub suab zoo ntawm koj cov nkauj nyiam hauv ib qho qauv. Qhov tseeb yog tias qee tus neeg nyiam ntses bass thaj tsam, thaum lwm tus, ntawm qhov tsis sib xws, tsis nyiam lawv. Kev nyiam ib txwm yog tus kheej heev; lub suab hauv tib lub mloog pob ntseg tau pom txawv los ntawm cov neeg sib txawv.
Cov kws tsim suab paj nruag, ua yeeb yam, thiab cov kws qhia suab paj nruag tau raug caw los ua cov kws tshaj lij. Txhua tus qhua muaj hnub nyoog sib txawv thiab muaj kev nyiam suab paj nruag sib txawv. Cov kev ntsuam xyuas tau ua tiav los ntawm kev mloog xya pawg suab paj nruag hauv txhua khub ntawm lub mloog pob ntseg: classical, jazz, pop, pob zeb, suab paj nruag hluav taws xob, nrog rau kev hais lus thiab suab paj nruag (qhov spectral ceev ntawm lub teeb liab yog qhov sib npaug ntawm qhov zaus, Nws tuaj yeem kuaj pom, piv txwv li, hauv lub plawv dhia, hauv yuav luag txhua yam khoom siv hluav taws xob, nrog rau ntau hom suab paj nruag).
Raws li kev soj ntsuam ntau yam ntxwv, los ntsuas qhov zoo ntawm lub suab kis tau tus mob, ib tug tshwj xeeb ntaus ntawv yog siv los ntsuas amplitude-frequency yam ntxwv thiab rhiab heev nyob rau hauv electroacoustics, audiometry thiab lwm yam zoo sib xws teb. Cov cuab yeej no feem ntau hu ua pob ntseg dag. Nrog nws cov kev pab, cov kws tshaj lij ntsuas cov qib ntawm acoustic to. Qhov ntsuas no yuav pab kom nkag siab seb lub cuab yeej "tuav" suab zoo. Piv txwv li, yog tias muaj qhov xau loj, cov suab paj nruag ua si hauv lub mloog pob ntseg tuaj yeem hnov los ntawm lwm tus, ntxiv rau cov ntses bass thaj tsam distorted.
Thiab xws li qhov taw qhia raws li kev ua haujlwm suav nrog xyuas qhov yooj yim ntawm kev siv - piv txwv li, seb lub mloog pob ntseg puas yooj yim rau quav, yooj yim npaum li cas los yog nyuaj nws yog los txiav txim seb lub pob ntseg nyob qhov twg rau pob ntseg sab laug thiab qhov twg rau sab xis, seb lub hau npog lossis rooj plaub muaj nyob rau hauv pob, seb lub mloog pob ntseg yog tam sim no built-in nyees khawm rau kev txais hu thiab tswj suab paj nruag playback, thiab lwm yam.
Lwm qhov kev ntsuas tseem ceeb yog kev nyab xeeb ntawm kev siv lub mloog pob ntseg. Nyob rau tib lub sijhawm, cov kws tshaj lij ceeb toom tias cov neeg uas raug kev txom nyem los ntawm kev hnov lus tsis hnov tsw tau tam sim no tau nce zuj zus. Ib qho ntawm qhov ua rau muaj kev tsis sib haum xeeb yog mloog suab paj nruag nrov ntawm lub mloog pob ntseg.
Zoo, cov neeg koom tau txheeb xyuas lub mloog pob ntseg yog qhov zoo tshaj plaws hauv suab zoo

Cov kws tshaj lij los ntawm Roskachestvo kuj pom zoo kom mloog cov suab paj nruag ntawm lub mloog pob ntseg tsis pub ntau tshaj peb teev hauv ib hnub thiab tsis pub ntau tshaj ob teev ua ke, thiab tsis yog qhov ntim siab tshaj plaws. Txwv tsis pub, muaj kev pheej hmoo ntawm pob ntseg puas thiab txo qhov hnov mob.
