Txoj Kev Sib Tw Rau Cov Quav QB-15?
Ib qho kev ntxhov siab rau kuv raws li lub mloog pob ntseg - thiab ua ib lub kiv cua ntawm lub suab nrov-txiav luam yeeb headphones - yog tias nws tau nyuaj ua kom pom zoo rau cov pob ntseg hauv NC uas tsis yog Bose QC-15 . Lub QC-15 muaj kev sib txeeb ua ke ntawm kev nplij siab zoo, tsis tawm suab nrov nrov, zoo suab zoo thiab kev txav mus los. Koj tuaj yeem pom zoo dua sound-siab NC lub xov tooj (xws li lub PSB M4U 2) thiab ntau lub compact NC headphones (zoo li AKG K490 NC), tab sis koj nrhiav tsis tau ib yam dab tsi uas yog txaus siab tag nrho ntawm QC-15.
Kuv tsis paub tseeb tias lub mloog pob ntseg los ntawm Samsung yuav yog thawj qhov tseeb rau hauv QC-15. Tseeb, Samsung tus thawj coj hauv cov khoom siv hluav taws xob, tab sis headphones yog ib qho ntawm ob peb cheeb tsam uas nws tsis yog ib tug neeg uas ua ntawv. Tab sis thaum kuv muab qhov Qis tshaj tawm ceev ceev, kuv txoj kev kub siab ncaws tawm sai.
Kuv tsis tau txais lub sijhawm los ua qhov kev sojntsuam zoo tshaj theem Qis, tab sis kuv tau khiav ob peb qhov kev ntsuas thiab khiav txhua yam kuv nyiam kev xeem los ntawm nws. Nov yog qhov kuv pom.
Tag Nrho, Qib Tshaj lawm muaj lub suab ncaj ncees thiab nruab nrab, uas yog raws nraim li kuv (thiab, tej zaum, feem ntau cov mloog) xav tau nyob hauv lub mloog pob ntseg. Qhov nruab nrab, tshwj xeeb tshaj yog, tau ua kom zoo. Vocals sounded ntau dua ntuj tshaj nrog ntau lub suab-txiav luam yeeb headphones, ntau dua nyob rau hauv kab ntawm dab tsi uas kuv tau siv los ntawm lub mloog zoo siab headphones . Lub xim sonic kuv tau hnov hauv suab yog me me, thiab txais tos: ib qho kev lag luam me me los yog "muaj zog ncov" nyob rau hauv qis dua treble, ncig 3 kHz. Qhov no ua rau cov suab nrov zoo li James Taylor yooj yim me ntsis, tab sis nws kuj ua rau cov suab nrov zoo li Toto's "Rosanna" sounds tad brighter dua kuv xav tau. Nws kuj ua rau Taylor cov acoustic guitar suab me ntsis edgy. Tab sis rov qab, cov no yog cov xim ntawm koj tus kheej kom pom hauv cov kev lag luam zoo tshaj plaws hauv cov nqi no.
Tsis muaj qhov sib txawv hauv lub suab nrog lub suab nrov txiav tawm los yog tawm. Kuv yeej nyiam nws zoo dua qub nrog NC. NC ua rau kom ceev nrooj ntawm lub ntses bass thaj tsam me ntsis, muab ib qho khoom plig zoo nkauj (rau kuv saj, tsawg kawg) ntawm qhov muaj zog thiab lub zog. Nrog NC tawm, cov ntses bass thaj tsam me ntsis boomy.
Kuv ntseeg leej twg yuav rave txog theem Qis tshaj sab nraud treble qhia thiab cua, tab sis tsis muaj leej twg yuav hu nws edgy los yog hnyav. Lub thauv treble zoo nkaus li ib ntsis muted, tsis txaus los hloov lub tonal tshuav, tab sis txaus tias lub suab tsis yog txhua yam uas dav rau kuv. Tab sis nws tsis tshua muaj lub suab nrov ntawm kev txiav luam yeeb headphones, PSB M4U 2 yog tsuas yog kos kuv tau xav txog.
Zuag qhia tag nrho, kuv xav hais tias qhov no yog ib qho zoo dua-suab NC xov tooj uas kuv tau hnov - tsis zoo li M4U2, tab sis zoo nkauj ze. Nws zoo dua li QC-15? Kuv tsis muaj QC-15 ntawm kev sib piv, tab sis Qis Dua li zoo li suab ntau me ntsis ntxiv dua li qhov kuv nco txog ntawm kuv cov neeg caij npav QC-15.
Tam sim no cia saib seb nws ntsuas ........

Kev Tshaj Sim Ntawm Kev Ntsuas: Kev Tshaj Tawm
Los ntsuas qhov Qib Tshaj, Kuv siv kuv GRAS 43AG pob ntseg / cheek simulator, lub Clio 10 FW suab analyzer, lub laptop computer khiav TrueRTA software nrog M-Audio MobilePre USB audio interface, thiab Musical Fidelity V-Tau lub mloog xov tooj cua amplifier. Kuv muab cov lus teb rau cov lus nug txog pob ntseg (ERP), ntxig taw tes rau qhov chaw uas koj xib teg tshuam nrog lub axis ntawm koj lub pob ntseg pob ntseg thaum koj nias koj txhais tes tiv thaiv koj lub pob ntseg.
Daim duab saum toj no qhia tau hais tias lub pob ntseg ntawm lub mloog zoo li cas yog qhov txawv. Cov kab ntsuab yog cov lus teb nrog NC, cov kab xiav nrog NC nrog. Cov neeg txiav txim tseem tseem tawm ntawm qhov kev txiav txim siab ntawm lub pob ntseg "tseeb". Tab sis ib lub mloog pob ntseg uas xa lub teb tias nyob ze rau ib txoj kab ncaj nraim, nrog rau tej zaum me ntsis boost hauv cov ntses bass thaj tsam thiab lwm boost ncig roughly 3 kHz, feem ntau yog suab zoo zoo.
Qib tshaj qhov lus teb yog ib qho yooj yim tiaj tus, nrog ib tug me me poob hauv nruab nrab ntawm 400 Hz thiab 2 kHz (los yog me ntsis boost txhua qhov txhia chaw, nyob ntawm seb koj saib nws). Dab tsi yog qhov tseem ceeb tshaj yog tias qhov kev hloov no tsuas hloov nrog NC los yog tawm. PSB qhov Paul Barton qhia rau kuv tias qhov tiag tiag, nyuaj tiag tiag ua, thiab qhov tseeb tias kuv tsis tshua pom cov kev ntsuas no zoo li yog qhov pov thawj tias nws yog lawm - thiab tias muaj qee qhov kev lag luam loj tom qab Theem Tshaj.

Qib dua Kev Ntsuas: Rho Tawm
Daim duab no qhia tau hais tias qhov kev sib cais (los yog lub suab qeeb tsis muaj peev xwm) ntawm Qib Siab (xim kab xiav) tiv thaiv kab Qib Bose QC-15 (ntsuab khiav). Qib qis tshaj 75 dB qhia tias kev tawm suab ntawm sab nraud nrov - ie, 65 dB ntawm cov ntawv qhia txhais tau hais tias yog -10 dB txo qis sab nraum lub suab ntawm lub suab nrov ntawd. Qhov qis ntawm kab yog nyob rau hauv daim qauv, qhov zoo dua.
Rau qhov zoo tshaj plaws ntawm kuv qhov kev paub, Qib dhau los yog lub pob ntseg nkaus xwb uas kuv tau sim tias ntau dua lossis tsawg dua qhov sib ntxiv ntawm lub suab nrov qog tsis txaus ntawm QC-15 nyob rau hauv "jet engine band" ntawm 100 thiab 200 Hz. Raws li kev ntsuas kuv tau noj nyob rau hauv dav hlau, qhov no yog qhov feem ntau ntawm cov droning ntawm dav hlau xyaw nyob, thiab Qis dhau yog ib txoj hauj lwm zoo ntawm attenuating nws. Nws tseem muab lub QC-15 ib tug khiav rau nws cov nyiaj ntawm frequencies siab tshaj 1 kHz, txawm hais tias QC-15 muaj ib tug meej zoo ntawm 200 Hz thiab 1 kHz, thiab hauv qab 100 Hz. Lub suab ceev nrooj mloog suab paj nruag liab los ntawm kuv qhov kev xeem rig paub tseeb hais tias Qib Yeem lub suab txiav tawm yog zoo saum nruab nrab. (Ntxiv dua thiab, kuv tsis muaj QC-15 ntawm tes rau qhov kev sib piv sib txuas lus.)
Los ntawm kev sib tham ntawm ergonomics, Qib Dua li ob peb cov kauj ruam ntawm QC-15, mas vim nws tsis quav tiaj tiaj li nws yog tus loj heev thauj thiab loj loj kom haum haum hauv feem ntau lub hnab laptop.
Tab sis los ntawm qhov kev sib tham ntawm nta, Qib Yooj yooj yim tua cov QC-15. Qeb Tshaj Ua haujlwm tseem ua haujlwm (thiab tseem suab zoo, txawm tias) thaum nws cov roj teeb rov sau, uas QC-15 tsis ua. Thiab Qib Muaj Bluetooth Wireless, uas dua li cas qee cov neeg tau hais rau koj hais cov suab zoo zoo nkauj, zoo li koj tuaj yeem hnov hauv kuv qhov kev ntsuam xyuas dig muag hauv online .
Kuv xav tias kuv yuav tau siv sij hawm ntau ntxiv nrog rau Qib Siab - thiab zoo dua, lub davhlau yuav coj nws mus. Tej zaum lwm hnub ...
