NAD Viso I-HP-50 Impendulo Yezimvamisa
Nansi indlela engilinganisela ukusebenza kwe-Viso HP-50. Ngasebenzisa i-GRAS 43AG indlebe / isifuba simulator, isicwaningi somsindo se-Clio 10 FW, isofthiwe yekhompyutha ephathekayo eqhuba i-TrueRTA software ne-interface ye-audio audio ye-M-AudioPre USB, kanye ne-Musical Fidelity V-Can isikrini sekhanda lomsindo. Ngalinganisa izilinganiso ze-reference reference point (ERP), cishe iphuzu esikhaleni lapho intendeni yesandla yakho ihamba khona nge-axis yomngcwabo wakho wezintambo uma ucindezela isandla sakho ngokumelene nendlebe yakho - nokuthi ngabe ubuso bomshayeli we-HP-50 buhamba kanjani bekuyohlala lapho uyigqoka. Ngithuthele izindlebe ezungeze kancane kwendlebe / isifuba simulator ukuthola isikhundla esinikeza isisindo esiphezulu se-bass kanye nomphumela wesici kunawo wonke jikelele.
Ishadi elingenhla libonisa impendulo yemvamisa ye-HP-50 ngakwesokunxele (okwesibhakabhaka) nakwesokudla (izitshalo ezibomvu). Lesi silinganiso sithathwe ezingeni lokuhlola elibhekiswe kuma-94 dB @ 500 Hz, njengoba kunconywe ku-standard IEC 60268-7 isilinganiso sekhanda. Kukhona ukuvumelana okuncane mayelana nalokho okwenza "impendulo" emibi yekhanda kuma-headphones, kodwa leli shidi likuvumela ukuba uthole umbono wezinhloso wokuthi i-HP-50 ihlelwe kanjani.
Impendulo ye-HP-50 ibonakala ifana uma iqhathaniswa nama- headphones amaningi engikulinganisiwe , ngokuthuthukiswa okuncane futhi okubanzi phakathi kwe-2 kHz no-8 kHz. Umehluko ekuphenduleni kwamashaneli amabili mhlawumbe ngenxa yokungalingani okufanelwe endlebeni / induna yesimiso; zombili zimelela impendulo engcono kakhulu engikwazi ukuyithola esiteshini ngasinye.
Ukuzwela kwe-HP-50, kulinganiswe nesignali esingu-1 mW ebalwe i-32 ohms impedance ehlukaniswe kusuka ku-300 Hz kuya ku-3 kHz, ngu-106.3 dB.

NAD Viso HP-50 vs. PSB M4U 1
Ishadi lapha libonisa impendulo yemvamisa ye-HP-50 (umkhondo ohlaza okwesibhakabhaka) uma kuqhathaniswa ne-PSB M4U 1 (i-trace green), eyabhalwa nguPaul Barton. Njengoba ubona, izilinganiso zifana kakhulu, ne-HP-50 enamandla angaphansi kwe-1 kHz kanye namandla angaphezu kwe-2 kHz.

NAD Viso HP-50 Impendulo, 5 vs. 75 Ohms
Ukuphendula okuphindaphindiwe kwe-HP-50, isiteshi esifanele, uma sidliwe yi-amp (Musical Fidelity V-Can) nge-5 ohms impedance yokukhipha (ukulandelela obomvu), futhi i-impedance engu-75 ohms yokuphuma komkhiqizo (i-trace green). Okufanelekile, imigqa kufanele ihambe ngokugcwele - njengoba yenza lapha - ebonisa ukuthi uhlamvu lwe-HP-50 lwe-tonal ngeke lushintshe uma uluxhuma kumthombo wamandla omthombo ophansi, njengama-laptops amaningi nama-smartphone angabizi.

NAD Viso HP-50 I-Decay Spectral
Isakhiwo se-spectral (waterfall) se-HP-50, isiteshi esifanele. Izindebe ezindala eziluhlaza okwesibhakabhaka zikhombisa ukuhlaselwa, okuvamile okungathandeki. Lephonephone ibonisa kakhulu (futhi mhlawumbe nje kuphela uma ezwakalayo) ehlangene ku-1.8 kHz ne-3.5 kHz.

I-VAD i-HP-50 Isolation
Ukuhlukaniswa kwe-Viso HP-50, isiteshi esifanele. Izinga elingezansi ku-75 dB likhombisa ukunakekelwa komsindo wangaphandle - okusho ukuthi, 65 dB eshadini kusho ukunciphisa -10 dB emisindeni engaphandle kule mvamisa. I-line engezansi ishadi, kungcono. Ukuhlukaniswa kwe-HP-50 kuvelele ngekhanda le-ear-over, ekunciphiseni imisindo engaphandle ngo -15 dB ku-1 kHz nangaphezulu kuka -40 dB ku-8 kHz. Qaphela ukuthi akukho ukunciphisa okuphawulekayo emazingeni angaphansi kwe-200 Hz, ngakho-ke i-HP-50 ngeke ikwenze okuningi ukusika umsindo wejet ye-jet.
