Inkokeli kwireyithingi yee-headphones ezingenazingcingo: I-Sony WH-1000XM2
I-Roskachestvo kunye neNdibano yeHlabathi yeMibutho yoVavanyo lwaBathengi (ICRT) uphando lweemodeli ezahlukeneyo ze-headphone ezivela kwiindidi zamaxabiso ahlukeneyo. Ngokusekelwe kwiziphumo zophando, ukulinganiswa kwezona zixhobo zingcono ezikhoyo kubathengi baseRashiya zahlanganiswa.
Lilonke, iingcali zafunda izibini ze-93 zeengcingo kunye neeperi ze-84 zee-headphones ezingenazintambo ezivela kwiimpawu ezahlukeneyo (iimodeli ze-studio ezichwephesha azizange zivavanywe). Zonke iimodeli zavavanywa kwiiparamitha ezinjengomgangatho wenkqubo yokuhambisa umqondiso wesandi, ukuqina kwee-headphones, ukusebenza, umgangatho wesandi kunye nokulula ukusetyenziswa.
Uvavanyo ngokwalo lwenziwa kwilabhoratri yamazwe ngamazwe ekhokelayo esebenza ngokwe-ISO 19025 standard (umgangatho womgangatho owamkelwa nguMbutho waMazwe ngaMazwe weMigangatho).
Izixhobo ezikhethekileyo zasetyenziselwa ukuvavanya iiparameters ezifana nomgangatho wenkqubo yokuhanjiswa kwesignali yomsindo, amandla ee-headphones kunye nokusebenza kwazo. Umgangatho wesandi kunye nokulula kweso sixhobo kuhlolwe ziingcali. Itekhnoloji ayinakho ukwenza uvavanyo olunjalo.
Kuyathakazelisa ukuba abanye abavelisi be-headphones abangengochwepheshe babonisa uluhlu olubanzi kakhulu lwee-frequencies eziveliswayo, okokuqala, akusoloko kunengqiqo, kwaye okwesibini, kaninzi ayinyani.
“Ukuva komntu kuyilwe ngendlela yokuba eve izandi ezinezandi ezimalunga nama-20 ukuya kuma-20000 Hz. Yonke into engaphantsi kwe-20Hz (infrasound) kunye nayo yonke into engaphezulu kwe-20000Hz (i-ultrasound) ayibonwa yindlebe yomntu. Ngoko ke, akucaci kakuhle xa umenzi wezindlu (ongeyena uchwepheshe) i-headphones ebhala kwinkcazo yobugcisa ukuba baphinda bavelise ama-frequencies kwi-10 - 30000Hz. Mhlawumbi uthembele kubathengi kungekuphela nje abasuka emhlabeni. Enyanisweni, kudla ngokuvela ukuba iimpawu ezibhengeziweyo zikude kakhulu kunezo zokwenyani, "utshilo uDaniil Meerson, injineli eyintloko yezandi kwisikhululo sikanomathotholo "I-Moscow Ithetha".
Kwakhona ukholelwa ukuba xa ukhetha i-headphones kufuneka uhlolisise umgangatho ozwakalayo womculo owuthandayo kwimodeli ethile. Inyaniso kukuba abanye abantu bathanda i-bass, ngelixa abanye, ngokuchaseneyo, abayithandi. Izinto ezikhethwayo zihlala zizimele; isandi kwii-headphone ezifanayo sibonwa ngokwahlukileyo ngabantu abahlukeneyo.
Abadali bomculo, abadlali beqonga, nootitshala bomculo bamenywa njengeengcali. Zonke iindwendwe zineminyaka eyahlukeneyo kwaye zinokukhetha ezahlukeneyo zomculo. Iimvavanyo zenziwa ngokumamela iiseti ezisixhenxe zomculo kwiperi nganye yee-headphones: i-classical, i-jazz, i-pop, i-rock, umculo we-elektroniki, kunye nentetho kunye nengxolo epinki (ubuninzi bembonakalo yomqondiso onjalo buhambelana ngokungafaniyo nokuphindaphinda, inokubonwa, ngokomzekelo, kwisingqi sentliziyo, phantse kuzo naziphi na izixhobo zombane, nakuninzi lweentlobo zomculo).
Ngokuphathelele ukuvavanya iimpawu ezahlukeneyo, ukuvavanya umgangatho wokuhanjiswa kwesandi, isixhobo esikhethekileyo sasetyenziselwa ukulinganisa iimpawu ze-amplitude-frequency kunye novakalelo kwi-electroacoustics, audiometry kunye nezinye iinkalo ezifanayo. Esi sixhobo sisoloko sibizwa ngokuba yindlebe eyenziweyo. Ngoncedo lwayo, iingcali zivavanya inqanaba lokuvuza kwe-acoustic. Esi salathisi sinceda ukuqonda ukuba isixhobo "sibambe" isandi kakuhle. Ngokomzekelo, ukuba kukho ukuvuza okukhulu, umculo odlalwa kwii-headphone unokuviwa ngabanye, kunye ne-bass iyagqwetheka.
Kwaye isalathiso esinjalo njengokusebenza kubandakanya ukujonga ukusetyenziswa lula-umzekelo, ukuba i-headphones kulula ukuyisonga, kulula kangakanani okanye kunzima kangakanani ukufumanisa ukuba i-earphone iphi indlebe yasekhohlo kunye nendawo ekunene, nokuba i-cover okanye i-earphone. i-case ifakwe kwiphakheji, nokuba ngaba ii-headphones zikhona amaqhosha akhelwe ngaphakathi okufumana iifowuni kunye nokulawula ukudlala komculo, njl.
Enye iparameter ebalulekileyo kukhuseleko lokusebenzisa i-headphones. Kwangaxeshanye, iingcali zilumkisa ngelokuba inani labantu abanengxaki yokungeva kakuhle ngoku linyuke kakhulu. Omnye unobangela wolu kuphazamiseka kukuphulaphula umculo ongxolayo kwii-headphone.
Ewe, abathathi-nxaxheba bachonge ii-headphones ezineentambo njengezona ziphezulu kumgangatho wesandi
I-Sennheiser HD 630VB, i-wireless-Sony WH-1000XM2, i-Sennheiser RS175, i-Sennheiser RS 165.
Iimodeli ezi-5 eziphezulu ezingenazingcingo ezikhokele kuzo zonke izikhombisi ezivavanyiweyo ziquka:
- SonyWH-1000XM2;
- I-Sony WH-H900N yiva kwi-2 Wireless NC;
- I-Sony MDR-100ABN;
- Sennheiser RS 175;
- ISennheiser RS 165.
Iintambo ezintathu ezigqwesileyo:
- I-Sennheiser HD 630VB (amanqaku aphezulu omgangatho wesandi);
- I-Bose SoundSport (iOs);
- Sennheiser Urbanite I XL.
Iingcali ezivela eRoskachestvo zikwacebise ukumamela umculo kwii-headphones ezingekho ngaphezu kweeyure ezintathu ngosuku kwaye zingabi ngaphezu kweeyure ezimbini ngokulandelelana, kwaye kungekhona kwivolumu ephezulu. Ngaphandle koko, kukho umngcipheko wokulimala kwendlebe kunye nokuncipha kovakalelo lokuva.
