Moeta-pele oa litekanyetso tsa li-headphones tse se nang mohala: Sony WH-1000XM2
Roskachestvo mmoho le Seboka sa Matjhaba sa Mekhatlo ya Teko ya Bareki (ICRT) lipatlisiso tsa mefuta e fapaneng ea li-headphone tse tsoang mefuteng e fapaneng ea theko. Ho itšetlehile ka liphello tsa thuto, tekanyo ea lisebelisoa tse molemo ka ho fetisisa tse fumanehang ho bareki ba Russia e hlophisitsoe.
Ka kakaretso, litsebi li ithutile lipara tse 93 tsa li-wireless le lipara tse 84 tsa li-headphone tse se nang mohala tse tsoang lihlahisoa tse fapaneng (mefuta ea litsebi tsa studio ha ea ka ea lekoa). Mefuta eohle e ile ea lekoa ka mekhahlelo e kang boleng ba tsamaiso ea molumo oa molumo, ho tšoarella ha li-headphone, ts'ebetso, boleng ba molumo le boiketlo ba tšebeliso.
Teko ka boeona e entsoe ka laboratoring e etelletseng pele ea machabeng e sebetsang ho latela maemo a ISO 19025 (tekanyetso ea boleng e amohetsoeng ke Mokhatlo oa Machabeng oa Boemo).
Ho ile ha sebelisoa lisebelisoa tse khethehileng ho lekola likarolo tse kang boleng ba sistimi ea phetisetso ea molumo, matla a li-headphone le ts'ebetso ea tsona. Boleng ba molumo le boiketlo ba sesebelisoa li ile tsa lekoa ke litsebi. Theknoloji ha e khone ho etsa tlhahlobo e joalo.
Hoa thahasellisa hore baetsi ba bang ba li-headphones bao e seng litsebi ba bonts'a mefuta e mengata haholo ea maqhubu a hlahisitsoeng, ao, pele, a sa utloahaleng kamehla, 'me ka lekhetlo la bobeli, hangata ha se' nete.
“Kutlo ea motho e entsoe ka tsela eo e ka utloang melumo e nang le maqhubu a ka bang 20 ho isa ho 20000 20 Hz. Ntho e 'ngoe le e' ngoe e ka tlaase ho 20000Hz (infrasound) le ntho e 'ngoe le e' ngoe e ka holimo ho 10Hz (ultrasound) ha e lemohuoe ke tsebe ea motho. Ka hona, ha ho hlake hantle ha moetsi oa li-headphones tsa ntlo (e seng setsebi) a ngola ka tlhaloso ea tekheniki hore li hlahisa maqhubu a mangata ka 30000 - XNUMXHz. Mohlomong o tšepile bareki e seng ba tšimoloho ea lefatše feela. Ha e le hantle, hangata ho fetoha hore litšobotsi tse boletsoeng li hole haholo le tsa 'nete, "ho boletse Daniil Meerson, moenjiniere ea ka sehloohong oa molumo oa seea-le-moea "Moscow Speaks".
O boetse o lumela hore ha u khetha li-headphone u lokela ho hlahloba boleng ba molumo oa 'mino oo u o ratang ka mokhoa o itseng. 'Nete ke hore batho ba bang ba rata li-bass, ha ba bang, ho fapana le hoo, ha ba li rate. Likhetho li lula li le motho ka mong; molumo oa li-headphone tse tšoanang o bonoa ka tsela e fapaneng ke batho ba fapaneng.
Baetsi ba ’mino, libini, le matichere a ’mino ba ile ba mengoa e le litsebi. Baeti bohle ke ba lilemo tse fapaneng 'me ba na le likhetho tse fapaneng tsa' mino. Liteko li ile tsa etsoa ka ho mamela lihlopha tse supileng tsa 'mino ho li-headphones tse peli: classical, jazz, pop, rock,' mino oa elektroniki, hammoho le lerata la puo le lepinki (boima ba pontšo ea lets'oao le joalo bo lekana ka tsela e fapaneng le khafetsa, e ka bonoa, ka mohlala, ka morethetho oa pelo, hoo e batlang e le lisebelisoa leha e le life tsa elektronike, hammoho le mefuta e mengata ea 'mino).
Ha e le ho lekola litšobotsi tse fapaneng, ho lekola boleng ba phetisetso ea molumo, sesebelisoa se ikhethileng se ile sa sebelisoa ho lekanya litšobotsi tsa amplitude-frequency le kutlo ho electroacoustics, audiometry le masimo a mang a tšoanang. Hangata sesebelisoa sena se bitsoa tsebe ea maiketsetso. Ka thuso ea eona, litsebi li lekola boemo ba ho lutla ha acoustic. Letšoao lena le thusa ho utloisisa hore na sesebelisoa se "tšoara" hantle. Ka mohlala, haeba ho lutla ho hoholo, ’mino o letsoang li-headphone o ka utluoa ke ba bang, ’me bass e sothehile.
'Me pontšo e kang ts'ebetso e ne e kenyelletsa ho hlahloba boiketlo ba tšebeliso - mohlala, hore na li-headphone li bonolo ho phutha, ho bonolo hakae kapa ho thata hakae ho tseba hore na tsebe ea tsebe e hokae le hore na e hokae, ebang ke sekoahelo kapa case e kenyelelitsoe ka har'a sephutheloana, hore na li-headphone li teng li-buttons tse hahelletsoeng bakeng sa ho amohela mehala le ho laola ho bapala ha 'mino, joalo-joalo.
