Kunyunyisa Kwechokwadi KweBose QC-15?
Chimwe chezvinhu zvinondigumbura semuongorori wepurofoni-uye sechivhiringidzi -kuregedza headphones - ndeyekuti zvakave zvakaoma kurumbidza chero humwe-nzeve NC muenzaniso kunze kweBose QC-15 . IQ-15 ine kukunda kusanganiswa kwekunyaradza kwakanyanya, kusinganzwisisiki runyararo ruregerero, kunaka kwakanaka kwehutano uye kushandiswa. Iwe unogona kuwana zviri nani-kutinhira zvinyorwa zvenyika NC (kufanana nePPB M4U 2) uye mamwe makonkoni eNC compact (kufanana neAkg K490 NC), asi haugoni kuwana chimwe chinhu chinogutsa chizere pa QC-15.
Ini chokwadi ndakanga ndisingafungi kuti matefoni kubva kuSamsin angave ari wokutanga kupikisa zvechokwadi QC-15. Zvechokwadi, Samsung ndiyo mutungamiri mumutengi wemagetsi, asi headphones ndeimwe yezvikamu zvishomanana zvisingambove mutambi. Asi pandakapa Nhamba Pamusoro pekuteerera nekukurumidza, kushingaira kwangu kwakakunda nokukurumidza.
Handina kuwana mukana wekuita tsananguro yakawanda yeWhite Over, asi ini ndakamhanya zvishoma zviyero uye ndinoshandisa zvose zvandinoda zvidzidzo zvekuedza kuburikidza nazvo. Heino izvo zvandakawana.
Pasi pose, iyo Level Over ine inowanzoperera uye isingarereki, izvo chaizvoizvo ini (uye, zvichida, vakawanda vanoteerera) vanoda mune sefoni. Pakati pepakati, kunyanya, zvakange zvakashamisa kuchena. Vocals yakaratidza zvakawanda zvepanyama kupfuura kunyanya kunzwika-kubvisa mafoni, kunyanya mumutsara wezvandakawanzwa kutinzwa kubva kune zvakanaka mahedhead headphones . Iyo imwe sonic coloration yandakanzwa mumhanzi yaiva shoma, uye yakagamuchirwa: kukurudzira zvishomanana kana "kuvepo kwepamusoro" mudenga rakadzika, kunenge 3 kHz. Izvi zvakaita kuti vanhu vakagadzikana vanzwika saJames Taylor vaite nyore kunzwisisa, kunyange zvazvo yakaitawo mifananidzo yakajeka inzwi reToto ya "Rosanna" inonzwika kupfuura zvandinoda. Zvakaitawo Taylor's acoustic gitare runyararo ruduku. Asi zvakare, idzi ndidzo dzorudzi ruvara rwaunogona kuwana kunyange kunyange zvakanakisisa kunyunyuta mumatengo aya.
Ikoko kwakanga kusina musiyano wakakura mumutinhiro nekunzwa kuridza kana kuvhara. Ini chaizvo ndaifarira zvishoma zviri nani neCN on. IC inoratidzika kuomesa zvingoro zvishoma, zvichipa kusanganiswa kwakakwana kwakakwana (nokuda kwandinonaka, kunyanya) kwehutano uye simba. NeCN off, mabhasi airema zvishoma.
Ini ndinopokana kuti ani zvake achatsvaga pamusoro peNhamba yepamusoro yepamusoro-soro dhesi nemhepo, asi hapana anozozvitumidza kuti mhemberero kana kuti utsinye. Kudengera kwepamusoro kunoratidzika kunge kwakangozununguka, kwete kukwana kuchinja tanal balance, asi zvakakwana kuti inzwi racho harisi iro rose rakapararira kwandiri. Asi hazviwanzovi nekutinhira kubvisa headphones, iyo PSB M4U 2 ndiyo chete iyo yandingafunga.
Pasi pose, ndingati izvi ndeimwe yemapurisa anonyoresa NC anonzwa - kwete zvakanaka seM4U2, asi ari pedyo. Izvo zviri nani here kupfuura QC-15? Ndakanga ndisina QC-15 pfupi kuti ndienzanise, asi Level Over yakaita sokuti inonzwika zvishoma zvinosanganisira zvandinenge ndichiyeuka kubva kune dzimwe ndege dzakatakura QC-15.
Iye zvino ngationei kuti inodini ........

Nharaunda Pamusoro Pemaitiro: Mhinduro ye Frebuuncy
Kuti ndienzane neNhamba Ipamusoro, ndakashandisa GRAS 43AG nzeve / cheek simulator, Clio 10 FW analyzer analyzer, yeComputer laptop yeW TrueRTA software neIm-Audio MobilePre USB inowanikwa mazwi, uye Musical Fidelity V-Can headphone amplifier. Ndakatarisa mhinduro dzenguva dzemhinduro dze nzeve reference point (ERP), inenge iyo inzvimbo iyo nzvimbo yako yemichindwe inoputirana ne-axis yenzwi rako rekunzwa kana iwe uchisimudza ruoko rwako kurwisana nenzeve yako.
Icho chati chiri pamusoro apa chinoratidza kuti mhinduro yehepphone inofanana sei nehuwandu. Icho chinyararire chekuita ndiyo mhinduro neCN off, ruvara rwebhuruu runowanikwa neCN on. Nhengo dzejeri dzichiri kunze pane izvo zvinoreva "kukodzera" misoro yekupindura. Asi sefoni inopa mhinduro iri pedo nepamusoro-soro, pamwe pamwe nekusimudzira zvishoma mumabhasi uye imwe kukurudzira inenge 3 kHz, kazhinji inonzwika zvakanaka.
Nhamba yePanning Over inoshamisa, inotonhora mukati mekatikati pakati pe 400 Hz uye 2 kHz (kana kukurudzira zvishoma kune dzimwe nzvimbo, zvichienderana nekutaridzirwa kwako sei). Chii chinonyanya kukosha ndechekuti mhinduro haigoni kuchinja neCN kana kuti inopera. PSB yaPauro Barton inondiudza kuti izvo chaizvoizvo, zvakaoma chaizvo kuita, uye kuti ini kazhinji ndisingaoni zviyero izvi zvinowirirana zvakasimba uchapupu hwokuti iye akarurama-uye kuti kune humwe hunyanzvi hunyanzvi huri shure kweNhare Over.

Nharaunda Pamusoro Pezviyero: Isolation
Iyi chati inoratidza kusarura (kana ruzha ruregerere ruzivo) rweNhare Over (blue trace) zvichienderana neBose QC-15 (vertical trace). Mazinga ari pasi pe75 dB anoratidza kucheneswa kwekunze kwezwi - kureva, 65 dB pane chati zvinoreva -10 dB kuderedza mumanzwi kunze kune iyo nguva inonzwika. Icho chasi pasi mutsetse chiri pa chati, zviri nani.
Kune zvakanakisisa zvekuyeuka kwangu, Level Over ndiyo chete purofoni yandakaidza iyo zvishoma kana zvishoma inopikisa ruzha rwekudzivirira ruzha rwe QC-15 mu "jet injini band" pakati pe100 ne 200 Hz. Maererano nezviyero zvandakatora mundiza, iyi ndiyo iyo yakawanda yekugadzirisa kwejet injini inogara, uye Level Over inoita basa rakakura rokurivhara. Inopawo Q-15 kumhanyira kwemari yayo pane zvakanyanya kupfuura 1 kHz, kunyange zvazvo QC-15 ine ruzivo rwakanaka pakati pe 200 Hz ne1 kHz, uye pasi pe100 Hz. Anokurumidza kuteerera rwiyo rwepinki runobva kuchirongwa changu rakazivisa kuti Level Over runyararo ruregerero ruri pamusoro pevhareji. (Zvakare, ndakanga ndisina QC-15 pane ruoko rwekuzvienzanisa.)
Kubva pakuona kwe ergonomics, Level Over inoratidzika sezvikamu zvitanhatu zvichidzika kubva kuQ-15, zvikurukuru nokuti haina kuvhara pasi saka zvinenge zvisingabatsiri kutakura uye zvakanyanya kukura kuti zvikwanise kunyatsogadzikana mune zvikwama zvakawanda zvepombi.
Asi kubva pakuona kwezvikamu, Nhamba Pamusoro inokurumidza kusvitsa QC-15. The Level Over ichiri kushanda (uye ichiri kunzwika zvakanaka, kunyange) apo bhati rayo rinoshandiswa rinopera pasi, izvo QC-15 haina. Uye Nhamba yepamusoro ine Bluetooth wireless, iyo pasinei nezvakaitwa nevamwe vanhu iwe chaizvoizvo inonzwika zvakanaka, sezvaunogona kunzwa mumuteereri wangu wekuteerera kwepamusoro paIndaneti .
Ndinoshuva kuti ndaizove nenguva yakawanda yekupedza neIndaneti Pamusoro - uye kunyange zviri nani, kuenda kunotora. Zvichida rimwe zuva ...
