Roskachestvo yakaratidza chiyero chewaya uye isina waya mahedhifoni anowanikwa muRussia

Mutungamiriri mune isina waya mahedhifoni chiyero: Sony WH-1000XM2

Roskachestvo pamwe neInternational Assembly yeConsumer Testing Organisations (ICRT) akaita zvakawanda tsvakiridzo yemhando dzakasiyana dzemahedhifoni kubva kumhando dzakasiyana dzemitengo. Zvichienderana nemhedzisiro yekudzidza, kuyerwa kwemidziyo yakanakisa inowanikwa kune vatengi veRussia yakaunganidzwa.

Pakazara, nyanzvi dzakadzidza 93 peya dzewaya uye 84 peya dzeasina waya dzemahedhifoni kubva kumhando dzakasiyana (nyanzvi dzema studio hadzina kuedzwa). Ese mamodheru akaedzwa pamatanho akadai semhando yeiyo inonzwika chiratidzo chekufambisa system, kusimba kwemahedhifoni, kushanda, ruzha rwemhando uye nyore kushandisa.

Iko kuyedzwa pachayo kwakaitwa murabhoritari yepasirese inotungamira iyo inoshanda zvinoenderana neISO 19025 standard (yemhando chiyero chakagamuchirwa neInternational Organisation for Standardization).

Midziyo yakasarudzika yakashandiswa kuongorora ma parameter akadai semhando yeodhiyo chiratidzo chekufambisa system, kusimba kwemahedhifoni uye kushanda kwawo. Ruzha rwemhando uye nyore kwechigadzirwa chakaedzwa nenyanzvi. Tekinoroji haigone kuongorora kwakadaro.

Zvinonakidza kuti vamwe vagadziri vevasiri nyanzvi dzemahedhifoni vanoratidza huwandu hwakanyanya huwandu hweakadzokororwa frequencies, izvo, kutanga, hazviiti nguva dzose zvine musoro, uye chechipiri, kazhinji hazvisi zvechokwadi.

“Kunzwa kwevanhu kwakagadzirwa nenzira yekuti inonzwa manzwi ane frequency inosvika 20 kusvika 20000 Hz. Zvose zviri pasi pe20Hz (infrasound) uye zvose zviri pamusoro pe20000Hz (ultrasound) hazvionekwe nenzeve yemunhu. Naizvozvo, hazvina kunyatsojeka kana mugadziri weimba (asiri nyanzvi) mahedhifoni anonyora mutsanangudzo yehunyanzvi iyo inobereka mafrequency muhuwandu hwe10 - 30000Hz. Pamwe ari kutarisira kutenga kwete vepanyika chete. Muchokwadi, zvinowanzoitika kuti hunhu hwakaziviswa huri kure kwazvo kubva kune chaihwo," akadaro Daniil Meerson, mukuru weinjiniya weredhiyo "Moscow Inotaura".

Anotendawo kuti pakusarudza mahedhifoni iwe unofanirwa kutarisa mhando yemhando yemimhanzi yaunofarira mune imwe modhi. Ichokwadi ndechokuti vamwe vanhu vanoda bass, asi vamwe, pane zvinopesana, havadi. Zvaanofarira zvinogara zviri zvemunhu oga; ruzha rwuri mumahedhifoni mamwe chete rwunonzwisiswa zvakasiyana nevanhu vakasiyana.

Vagadziri vemimhanzi, vaimbi, uye vadzidzisi vemimhanzi vakakokwa senyanzvi. Vese vaenzi ndevezera rakasiyana uye vane mhanzi yavanoda zvakasiyana. Miedzo iyi yakaitwa nekuteerera seti nomwe dzemimhanzi mupaya yega yega mahedhifoni: classical, jazz, pop, rock, mimhanzi yemagetsi, pamwe nekutaura uye ruzha rwepingi (kupenya kwechiratidzo chechiratidzo chakadaro kunopesana nekuwanda, inogona kuonekwa, semuenzaniso, mumoyo rhythms, munenge chero zvigadzirwa zvemagetsi, pamwe chete nemhando dzakawanda dzemimhanzi).

Kana zviri zvekuyedza hunhu hwakasiyana, kuongorora kunaka kwekufambiswa kwenzwi, mudziyo wakakosha wakashandiswa kuyera amplitude-frequency maitiro uye kunzwa mu electroacoustics, audiometry nemamwe minda yakafanana. Chigadzirwa ichi chinowanzonzi nzeve yekugadzira. Nekubatsira kwayo, nyanzvi dzinoongorora huwandu hweacoustic leakage. Ichi chiratidzo chinobatsira kunzwisisa kana mudziyo "wakabata" ruzha zvakanaka. Somuenzaniso, kana pakadonhera mvura yakawanda, mumhanzi unoridzwa mumahedhifoni unogona kunzwika nevamwe, uye bhesi racho rinovhiringika.

Uye chiratidzo chakadai sekushanda kwaisanganisira kutarisa kureruka kwekushandisa - semuenzaniso, kana mahedhifoni ari nyore kupeta, zviri nyore kana zvakaoma sei kuziva kuti iyo earphone iripi yekuruboshwe nzeve uye kupi kwekurudyi, ingave chivharo kana. kesi inosanganisirwa mupakeji, ingave mahedhifoni aripo akavakirwa-mukati mabhatani ekugamuchira mafoni uye kudzora mimhanzi kutamba, nezvimwe.

Imwe parameter yakakosha ndeyekuchengetedza kwekushandisa mahedhifoni. Panguva imwe cheteyo, vanamazvikokota vanonyevera kuti nhamba yevanhu vanotambura nokutadza kunzwa zvakanaka yawedzera zvakanyanya. Chimwe chezvikonzero zvechirwere ichi kuteerera mimhanzi ine ruzha pamahedhifoni.

Zvakanaka, vatori vechikamu vakaona mahedhifoni ane waya seakanakisa mumhando yeruzha
Sennheiser HD 630VB, isina waya - Sony WH-1000XM2, Sennheiser RS175, Sennheiser RS ​​​​165.

Iwo epamusoro mashanu asina waya modhi akatungamira mune ese akaongororwa zviratidzo aisanganisira:

• Sony WH-1000XM2;
• Sony WH-H900N inzwa pa 2 Wireless NC;
• Sony MDR-100ABN;
• Sennheiser RS ​​175;
• Sennheiser RS ​​165.

Matatu akanakisa waya:

• Sennheiser HD 630VB (yakanyanya mamakisi yemhando yeruzha);
• Bose SoundSport (iOs);
• Sennheiser Urbanite I XL.

Nyanzvi dzinobva kuRoskachestvo dzakakurudzirawo kuteerera mimhanzi pamahedhifoni kweanopfuura maawa matatu pazuva uye isingapfuuri maawa maviri akateedzana, uye kwete pahuwandu hwehuwandu. Zvikasadaro, pane njodzi yekukuvadzwa nzeve uye kuderera kwekunzwa.
