Dab tsi yog qhov txawv ntawm high-end headphones thiab low-end headphones?

Lub mloog pob ntseg zoo sib xws.Cov high-enduazoo dua, yog li hais lus.Yog li, dab tsi tiag tiag lub mloog pob ntsegkev ua tau zoosuav nrog?

(1) Ntau zaus:Tib neeg pom lub suab raws li kev hloov pauv hauv huab cua.Muaj ob txoj hauv kev uas qhov no ntsuas / sawv cev.Covtus nqintawm lub siab no (hu uaSPL), thiab zaus uas qhov kev hloov no tshwm sim.Tib neeg auditory sensors tuaj yeem ntes ntau dua 100 dB (Decibel) ntawm kev hloov hauvSPL, thiab suab nrog frequencies nruab nrab ntawm20 thiab 20,000 Hz (Hertz / Cycles ib ob).

Yog li, lub hom phiaj tseem ceeb ntawm lub mloog pob ntseg yog los muab cov kev paub zoo uas suav nrog ntau qhov kev nkag siab ntawm tib neeg li sai tau.Tab sis ob peb tus tuaj yeem, vim tias, vim muaj kev txwv hauv kev tsim khoom, kev txwv ntawm cov nqi tsim khoom, cov kev txwv ntawm cov cai ntawm physics ua tiav lub hom phiaj yog txhua yam tab sis yooj yim.

Cov neeg tsim khoom sim tsim lub mloog pob ntseg, uas tuaj yeem tsim muaj ntau zaus ntawm 20 thiab 20,000 Hz, ntawm txhua qhov kev nrov nrov (hais 20 mus rau 120 dB), xav tau tib lub zog (tso cov cim hluav taws xob zoo li qub), tsis muaj kev cuam tshuam (kev cuam tshuam thiab lwm yam). ).

Txij li cov tuam ntxhab tsis tuaj yeem ua tau raws li lub hom phiaj, lawv (yuav tsum tau) hais tias qhov sib txawv ntawm qhov saum toj no hauv lawv cov khoom.Lawv muab qhov xwm txheej no hauv daim ntawv+-dBs.Qhov kev sib txawv no kuj yog ib feem ntawm cov qauv specifications.

Kev tshawb fawb ntawm acoustics hais tias lub mloog pob ntseg zoo tshaj plaws (lossis ib qho khoom siv ua suab nrov rau qhov teeb meem) yuav tsum rov tsim dua li qhov yuav tsum tau ua.Hauv lub ntiaj teb suab xws li kev coj cwj pwm ntawm cov cuab yeej hu uaTus pas ntsuas-paj zaus teb. Tab sis hauv kev xyaum, tsis muaj tus cwj pwm zoo li no tuaj yeem ua tiav lossis nws nyiam los ntawm cov neeg siv khoom.Feem coob ntawm cov neeg siv kawg xav tau me ntsisBoom-thiab-sizzlehauv lawv lub suab.Yog li ntawd, manufacturers qee zaumsuablawv cov khoom los tsim ib hom suab nrov uas txawv ntawm qhov zoo tagnrho.Cov tuam txhab sib txawv muaj kev txhais lus sib txawv ntawm lawv cov khoom yuav tsum zoo li cas, lossis cov tuam txhab tsim lawv cov khoom khaws qee cov neeg siv khoom hauv siab.Li no txawm tias txawv lub mloog pob ntseg txhais tau hais tias zoo mloog, lawv feem ntau deviate deb ntawm lawv tus cwj pwm zoo.Qee qhov chaw tsim khoom ib txwm ua raws li qee yam kev txiav txim siab (hu uasuab) ntawm reproduced suab nyob rau hauv lawv cov khoom.Xws li lub suab hulub suabntawm cov chaw tsim khoom.

Txog tam sim no, nws yuav tsum paub meej tias yog vim li cas lub mloog pob ntseg sib txawv ua / yuav tsum suab txawv.Cov lus nug tom ntej yog - dab tsi ua rau lub mloog pob ntseg siab sib txawv.Zoo, lawv ob leeg

(a)tsim kom muaj ntau yam los ze zog rau lub suab zoo (uas nyuaj heev rau ua)
(b)tsim lub suab uas yog lawv USP
(c)coj tus cwj pwm zoo dua rau qee yam kev siv (cov khoom tshwj xeeb).

(2) Distortion:Distortion yog qhov tsis muaj peev xwm ntawm lub mloog pob ntseg los tsim cov ntawv raws nraim (qhov zaus, qhov amplitude) nws raug nug kom tsim.Distortion yog qhia nyob rau hauv daim ntawv ntawm feem pua ​​thiab feem ntau yog ib feem ntawm covspecification.Distortion feem ntau tsis xav tau.Cov khoom uas muaj kev sib txawv tsawg dua yog qhov nyuaj rau tsim, yog li raug nqi ntau dua.

(3) SPL:Cov khoom uas tuaj yeem ua tau zoo ntawm SPLs siab lossis qis SPLs yog qhov nyuaj rau tsim.Yog li lawv raug nqi ntau dua.Qhov no feem ntau yog qhov tsis saib xyuas ntawm cov khoom siv suab, uas yuav tsum yog tab sis, hmoov tsis, tsis yog ib feem ntawm cov qauv specifications.

(4) Cov khoom siv sib xws:Hauv lub ntiaj teb zoo tagnrho, lub mloog pob ntseg zoo tagnrho yuav ua si zoo nrog lwm yam khoom siv.Hmoov tsis zoo, qhov ntawd tsis yog li ntawd.Kev tsim lub mloog pob ntseg uas tuaj yeem ua si sib npaug zoo nrog lwm cov khoom siv sib txawv yog qhov nyuaj heev.Qee lub xov tooj high-end sim uayooj yim tsav, thaum tseem ua suab zoo.

Lawv hais tias, cov pov thawj ntawm paj npleg nyob rau hauv noj.Qhov no yeej muaj tseeb zoo nkauj heev thaum nws los txog rau suab reproduction.Txawm hais tias lub mloog pob ntseg high-end puas tsim nyog nws tus nqi lossis tsis tuaj yeem txiav txim siab los ntawm kev mloog nws.

High-end headphones muab ib tugkev paub visceral, ib qho uas tuaj yeem yogplig nplawm, thiab txawmsab ntsuj plig.Lub mloog pob ntseg zoo muaj peev xwm ua tauzoo thauj koj mus rauqhov chaw kaw cia, thiab ua rau koj xav tiaskoj nyob ntawd.Muaj kev nkag siabpalpabilitynyob rau hauv lub suab uas yuav ua rau tag nrho cov venue tuaj ciaj sia.Tag nrho cov ntawm cov hoob kawm nyob ntawm tag nrho cov rig ib tug yog mloog (lub mloog pob ntseg ib leeg ua tsis tau tag nrho cov khawv koob).Feem ntau qhov kev nkag siab ntawm realism koj tau txais los ntawm lub rig yog ib txoj haujlwm ntawm ntau npaum li cas nyiaj thiab kev siv zog tau mus rau hauv nws.
