Roskachestvo adapereka mawonedwe a mahedifoni opanda zingwe komanso opanda zingwe omwe amapezeka ku Russia
Mtsogoleri pazida zam'mutu zopanda zingwe: Sony WH-1000XM2

Roskachestvo pamodzi ndi International Assembly of Consumer Testing Organisations (ICRT) anachita zambiri kafukufuku wamitundu yosiyanasiyana yam'mutu kuchokera m'magulu osiyanasiyana amitengo. Malingana ndi zotsatira za phunziroli, chiwerengero cha zipangizo zabwino kwambiri zopezeka kwa ogula aku Russia chinapangidwa.

Pazonse, akatswiri adaphunzira ma 93 awiriawiri a mawaya ndi ma 84 a mahedifoni opanda zingwe ochokera kumitundu yosiyanasiyana (akatswiri a studio sanayesedwe). Zitsanzo zonse zinayesedwa pazigawo monga khalidwe la kayendedwe ka mauthenga omveka bwino, kulimba kwa mahedifoni, ntchito, khalidwe la mawu komanso kugwiritsa ntchito mosavuta.

Kuyesako komweko kunachitika mu labotale yotsogola yapadziko lonse lapansi yomwe imagwira ntchito molingana ndi ISO 19025 standard (mulingo wapamwamba wotengedwa ndi International Organisation for Standardization).

Zida zapadera zidagwiritsidwa ntchito kuyesa magawo monga mtundu wa makina otumizira ma audio, mphamvu ya mahedifoni ndi magwiridwe ake. Kumveka bwino komanso kuphweka kwa chipangizocho kunayesedwa ndi akatswiri. Zipangizo zamakono sizingathe kuwunika koteroko.

Ndizosangalatsa kuti ena opanga mahedifoni omwe si akatswiri amawonetsa maulendo angapo opangidwanso, omwe, choyamba, sizimveka nthawi zonse, ndipo kachiwiri, nthawi zambiri sizowona.

β€œKumva kwa anthu kunapangidwa m’njira yoti imamva phokoso lapafupifupi 20 mpaka 20000 Hz. Chilichonse chomwe chili pansi pa 20Hz (infrasound) ndi chirichonse pamwamba pa 20000Hz (ultrasound) sichidziwika ndi khutu la munthu. Chifukwa chake, sizodziwika bwino pamene wopanga mahedifoni am'nyumba (osakhala akatswiri) amalemba muzofotokozera zaukadaulo kuti amachulukitsa ma frequency a 10 - 30000Hz. Mwina akudalira ogula osati ochokera kudziko lapansi okha. M'malo mwake, nthawi zambiri zimakhala kuti mawonekedwe omwe adalengezedwa ali kutali kwambiri ndi zenizeni," adatero Daniil Meerson, injiniya wamkulu wa wailesi ya "Moscow Speaks".

Amakhulupiriranso kuti posankha mahedifoni muyenera kuyang'ana khalidwe la nyimbo zomwe mumakonda pamtundu wina. Chowonadi ndi chakuti anthu ena amakonda mabasi, pomwe ena, m'malo mwake, samawakonda. Zokonda nthawi zonse zimakhala zapayekha; phokoso la mahedifoni omwewo limadziwika mosiyana ndi anthu osiyanasiyana.

Okonza nyimbo, oimba, ndi aphunzitsi a nyimbo anaitanidwa monga akatswiri. Alendo onse ndi amisinkhu yosiyanasiyana komanso amakonda nyimbo zosiyanasiyana. Mayeserowa adachitika pomvetsera nyimbo zisanu ndi ziwiri pamutu uliwonse wamutu: classical, jazz, pop, rock, nyimbo zamagetsi, komanso kulankhula ndi phokoso lapinki (kuchuluka kwa mawonedwe a chizindikiro choterocho kumasiyana mosiyana ndi pafupipafupi, imatha kuzindikirika, mwachitsanzo, mumayendedwe amtima, pafupifupi pafupifupi zida zilizonse zamagetsi, komanso mitundu yambiri yanyimbo).

Ponena za kuyesa mawonekedwe osiyanasiyana, kuti awone momwe mamvekedwe amamvekedwe, chida chapadera chidagwiritsidwa ntchito kuyeza mawonekedwe a amplitude-frequency and sensitivity mu electroacoustics, audiometry ndi magawo ena ofanana. Chipangizochi nthawi zambiri chimatchedwa khutu lochita kupanga. Ndi chithandizo chake, akatswiri amawunika kuchuluka kwa kutayikira kwamayimbidwe. Chizindikirochi chimathandiza kumvetsetsa ngati chipangizocho "chimagwira" bwino. Mwachitsanzo, ngati pali phokoso lalikulu, nyimbo zomwe zimaimbidwa m'mahedifoni zimatha kumveka ndi ena, kuphatikizapo bass ndi zolakwika.

Ndipo chizindikiro choterocho monga magwiridwe antchito chimaphatikizapo kuyang'ana kumasuka kwa ntchito - mwachitsanzo, ngati mahedifoni ndi osavuta kupindika, momwe zimakhalira zosavuta kapena zovuta kudziwa komwe m'makutu uli pa khutu lakumanzere ndi komwe kumanja, kaya ndi chivundikiro kapena case ikuphatikizidwa mu phukusi, kaya mahedifoni alipo mabatani omangidwa kuti alandire mafoni ndikuwongolera kusewera kwa nyimbo, ndi zina.

Chizindikiro china chofunikira ndi chitetezo chogwiritsa ntchito mahedifoni. PanthaΕ΅i imodzimodziyo, akatswiri akuchenjeza kuti chiΕ΅erengero cha anthu amene ali ndi vuto losamva kumva bwino tsopano chawonjezeka kwambiri. Chimodzi mwa zifukwa zomwe zimayambitsa vutoli ndikumvetsera nyimbo zaphokoso pa mahedifoni.

Eya, otenga nawo mbali adazindikira mahedifoni okhala ndi mawaya ngati abwino kwambiri pamawu
Sennheiser HD 630VB, opanda zingwe - Sony WH-1000XM2, Sennheiser RS175, Sennheiser RS ​​​​165.

Mitundu 5 yapamwamba yopanda zingwe yomwe idatsogola pazizindikiro zonse zowunikiridwa ndi:

  • Sony MDR-100ABN;
  • Sennheiser RS ​​175;
  • Sennheiser RS ​​165.

Mitundu itatu yabwino kwambiri:

  • Sennheiser HD 630VB (chiwerengero chapamwamba chamtundu wamawu);
  • Bose SoundSport (ios);
  • Sennheiser Urbanite I XL.

Akatswiri ochokera ku Roskachestvo adalimbikitsanso kumvera nyimbo pamakutu osapitilira maola atatu patsiku komanso osapitilira maola awiri motsatizana, osati pamlingo waukulu. Apo ayi, pali chiopsezo cha kuwonongeka kwa khutu ndi kuchepa kwa kumva.
