Uninzi kunoma yimuphi umrhumo womculo othengiweyo uya kuba nempendulo yempendulo echazwe njengenye yeenkcukacha eziqhelekileyo. Iimpendulo eziphindaphindiweyo ziyafumaneka kwiintetho, i-headphone, ii-microphones, izikhulisi, abafumana i-CD / i-DVD / abadlali beendaba. abadlali / izixhobo eziphathekayo, kunye naliphi na inani lamanye amadivaysi alalelwayo okanye izinto . Abanye abakhiqizi banjengezinto zonke ezinobanzi obubanzi, kodwa amanani anjalo athetha kuphela inxalenye yebali kwaye ayilona isalathisi somgangatho osemgangathweni. Isethi yentloko yeefowuni ingabhala uluhlu lwempendulo yempendulo ye-Hz-34 kHz +/- 3 dB, kodwa kuthetha ukuthini ngempela?
Yintoni ephendula ngokuphindaphindiweyo?
Impendulo ephindaphindiweyo, enokuthi iboniswe rhoqo kwigrafu / ityati njengekhava, ichaza indlela ifowuni isabela kwisandi kwiinkalo. Ii-frequencies zilinganiswa kwi-hertz (Hz) kunye ne-x-axis yegrafu, ngezinga leengcinezelo zomsindo (SPL) elilinganiselwe kwi-decibels (dB) kunye ne-y-axis yegrafu. Uninzi lwemveliso uluhlu lweenkcukacha ezifihla ubuncinane ubuncinane be-20 Hz (i-lows) ukuya kwi-20 kHz (phezulu), oluqhelekileyo oluthathwa ngabantu. Ii-Frequencies apha ngasentla naphantsi kwezo manani zidlalwa ngokuba yi- wideband frequency response kwaye nazo zingaba zibalulekileyo. Ukulinganisa kwe-decibel kubonisa ukuhluka kobuninzi (cinga nje ngenyameko okanye umda wephutha) kwinqanaba levolumu kwaye isisombululo sihlala sisifana njani ukusuka kwi-lowest to theones. Uluhlu lwesithathu lwe-decibel luqhelekile kwiimpawu zempendulo zokuphendula.
Kutheni ukuphendula ngokuphindaphindiweyo kubalulekile
Unokuthabatha izithethi ezimbini, ezingafaniyo nezivakalisi ezifanayo kunye nokuphela komculo ovayo odlalwa ngokwahlukileyo nganye. Oku kwenzeka ngenxa yokuba abanye abasebenzisa i-hardware / i-software designs ezigxininisa amabhande athile ngamaxesha amaninzi, kungekhona ngokungafani nendlela umntu angenza ngayo utshintsho olumandla kunye ne-stereo equalizer . Isixa sokuhluka siyachaza indlela i-audio iya kuthinteka ngayo ngokuchaneka.
AmaPhuthi adla ngokufuna iimveliso kunye nezixhobo ezihambisa ukungathathi hlangothi (okanye ngokusondeleyo kunokwenzeka) impendulo yevama. Oku kubangela isignesha "yindlwana" ebonisa ukuba ulwalamano oluvakalayo phakathi kwezixhobo ezahlukeneyo, amazwi, kunye neetoni ezifanelekileyo ngaphandle kokugqithiseleyo okanye ukugxininisa nayiphi na ibhanti yamanqanaba athile. Okubalulekileyo, umculo unokunandipha ngokwemvelo njengoko wawubhalisiwe okokuqala kuba akukho tshintsho olunyanzelekileyo lokutshintsha. Yaye ukuba umntu ukhetha, ukulungelelanisa ngakumbi ngokulinganayo kusekho ukhetho.
Kodwa wonke umntu unelungelo lokuthandayo, izithethi ezininzi, iintloko zee-headphones kunye nezixhobo ezahlukahlukeneyo zinikezela ngokwazo izinto ezizodwa. Ngokomzekelo, isignin "ye-v-enziwe" yesandi isandisa iifom ephantsi kwaye iphakamileyo ngelixa uvala i-middle-range. Oku kunokubhenela abo baphulaphule uhlobo lweMDM, ip, okanye i-hip-hop yomculo (ukubiza ezimbalwa) ezibonisa ubuninzi beebhasi kwaye zihamba ngokukhawuleza. Isayinari yesandi "esimo esifanekileyo" ifana nesimo esifanayo, kodwa kunye neziganeko eziye zahlengahlengiswa kwinqanaba elincinci.
Ezinye iimveliso zenza isandi "sokuhlalutya" esenza ukuba phezulu (kunye ngamanye amaxesha ububanzi obuphakathi) ngelixa uhlaziya i-lows. Oku kungakuhle kulabo abafumana bephulaphule uhlobo lwemihla yamaculo okanye yomculo, phakathi kwabanye. Iisethi ze-headphones okanye izithethi ziza kukhulisa i-lows ngeli xesha likhawuleza ukuphakama kunye nobubanzi obuphakathi. Ngamanye amaxesha imveliso ibonakalisa isayinwa yesandi esilungelelaniso senye okanye ezininzi.
Impendulo ye-frequency iyasiza - kodwa asiyena yodwa into-ukujonga indlela izandi ezibonakala ngayo malunga nokuhlukana kwezixhobo kunye neenkcukacha zezinto ezizimeleyo. Imveliso ebonisa ukudibanisa ngokugqithisileyo okanye iipikhi kwiimpawu zikhokelela ekumanyeleni okanye ekukhatheni. Isantya apho amanqaku adlalayo kunye nasoloko (amaninzi afana nokuhlaselwa kunye nokubola) nayo yenza impembelelo enkulu kumava. Iintlobo zeMveliso zibaluleka ngokufanayo, kuba iifowuni kunye nezithethi ezineempendulo ezifanayo / ezifanayo zingaphinde zandile ezahlukeneyo ngenxa yendawo efunekayo ukuze nganye ibonise.
