Sezvo kuvamba rayo Aleksandrom Grehemom Bell yechipiri yezana rechigumi nemapfumbamwe remakore, pamahedhifoni kunge chakachinja kakawanda uye zvakasimba akapinda upenyu vanoda mimhanzi kwete chete havagoni kurarama mumhanzi pasina, asiwo vose mafeni kuteerera redhiyo panzira kushanda kana kuti "verenga" mumwe audiobook itsva, pasina apindire musha. With veMubatanidzwa dzinenge dzose musha PC headset uye sei kuva hunokosha chokufunga mhuri dzose. Asi munhu wose anoziva sei kusarudza pamahedhifoni uye chii zvinhu apo kutenga chishongedzo ichi vanofanira kuteerera?

Chinhu chokutanga kutsvaka pakusarudza pamahedhifoni, ichi Frequency siyana. Zvinofanira kurangarirwa kuti nheyo "zvikuru, zviri nani" iri nyaya anoshanda kwete nguva dzose. Saka sei kusarudza pamahedhifoni ne "kodzero" Frequency siyana? Chokutanga, zvinokosha kuziva kuti vanhu nzeve munganzwisisa frequencies kubvira 20 Hz 20 kHz. Kuvamba chidimbu ichi kukonzera "bass", uye mukuru-kakawanda machemero vari pamusoro. Nokuti Headphone zvakanaka kunokosha, kwete noupamhi kakawanda bhendi, asi yakarurama kubereka kakawanda muna chikuva ichi, pasina blockages, "mumbling" kana wheezing yakaderera frequencies uye pasina kukuya kana muridzo pamusoro uye pakati frequencies. Kazhinji, vagadziri zvose anoratidza huru hwokugadzira zvechadenga nhumbi, kusanganisira amplitude-kakawanda zviratidzo pamusoro kavha kana ari munyaya mirayiridzo.

Chimwe maitiro zvinokosha kusarudza Headphone ndiko kurwisa. Kutaura zvazviri, mamwe ane chishongedzo, maitiro ichi, mudziyo zvikuru simba anofanira kunge saka pamahedhifoni kuti optimum kuita, uye ndoda simba pamusoro inzwi kunobva ichi anopa. Zvichitaurwa zviri nyore, yakaderera yepamusoro mutambi, unogona batanidza pamahedhifoni ane impedance pamusoro 8-16 ohms, asi kuti zvakazara kunakidzwa mumhanzi hakushande - ichi pfungwa crackle yomunyika urongwa, gudzazwi ruzha uye dzimwe extraneous ruzha. Kana zvakabatana akadaro mutambi mukuru, "tarisisa" pamahedhifoni ane impedance pamusoro ohms 250, inzwi achava akanyarara chaizvo uye sandara - pamahedhifoni haazorambi kutamba, uye vachapera "zevezeve". Zvakanyanya Kunaka Panguva Yepamuviri nemishonga chikuva inotakurika mano - iri 32-64 ohms. ruzivo urwu vachakuudza sei kusarudza pamahedhifoni kuti mutambi "zvakarurama."

Chimwe chinokosha kuti yekudyidzana inokanganisa inzwi, ndiye nehanya. The zvakawanda maitiro ichi, kurira zviri kwazvo. Saizvozvowo, rezasi ari nehanya uye kuramba, yakanyarara pamahedhifoni izvi kuchaita kuridza inzwi.

Vazhinji vatengi asati kutenga chishongedzo ichi vari kufunga chii kusarudza - Vacuum pamahedhifoni kana "chakaipa". Panyaya iyi, zvakanaka kuti dzifunge pemanzwiro dzavo mudare Kuteerera uye nyaradzo chikonzero. Uyewo, ziva kuti kunyange kana muted, nyika yakatipoteredza mu Vacuum pamahedhifoni "akakurira" asi zvakasimba, saka ane mudziyo yakadaro, zviri zvinodiwa, vanyatsohuongorora kuyambuka mugwagwa uye kazhinji kuitwa zvakawanda panze inounganidzwa.

Uye chikamu chokupedzisira mubvunzo sei kusarudza headset ndiyo acoustic pamasikiro kukasaitwa kutengwa. Panyaya iyi pamahedhifoni vari "akazaruka", "namahwindo" uye "Semi-akazaruka". Kuwedzera pakuonekwa acoustic zvakagadzirwa kunokanganisa inzwi kuputira - mu "namahwindo" pamahedhifoni kunze nyika ichava se "muted" mumhanzi, uye vamwe havanzwi zviri playing pamahedhifoni enyu kunyange apo achitamba ari kumusoro chaizvo vhoriyamu. Asi pamahedhifoni "namahwindo" pane imwe drawback - hapana ruzha chinobuda rwemberi wall vakurukuri matsi uye zvinogona zvishoma akavhiringika.

Chimwe chezvinhu dzakakurumbira Vagadziri pamahedhifoni panguva vari makambani akadai «Koss», «Sennheiser», «Sony», «AKG» uye «Philips», asi pane zvimwe vagadziri, ichipa unhu Headphone pamusika uye chigadzirwa akakodzera kuteererwa.
