Okuningi kunoma yikuphi umkhiqizo womsindo owathengiwe kuzoba nempendulo yemvamisa efakwe njengenye yezincazelo ezijwayelekile. Izimpendulo zemivamisa zingatholakala ngezikhulumi, ama-headphones, ama-microphones, ama-amplifiers, abawamukeli, abadlali beCD / DVD / abezindaba. abadlali beselula / amadivaysi, nanoma iyiphi inamba yamanye amadivaysi alalelwayo noma izingxenye . Abanye abakhiqizi bathanda konke okwenziwe ububanzi obubanzi, kodwa izinombolo ezinjalo zikhuluma ingxenye kuphela yendaba futhi akuyona inkomba yekhwalithi yomsindo jikelele. Iqoqo le-headphones lingabhala ukuchazwa kwemvamisa ye-Hz-34 kHz +/- 3 dB, kodwa kusho ukuthini ngempela?
Kuyini Ukuphendula Ngokuvamile?
Impendulo yemvamisa, engavame ukuboniswa kumagrafu / ishadi njengejika, ichaza indlela idivayisi ephendula ngayo umsindo kumanethiwekhi amaningi. Ama-frequencies alinganiswa ku-hertz (Hz) eduze kwe-x-axis yesigrafu, ngezinga lokucindezela kwengqondo (SPL) elinganiselwe kuma-decibel (dB) eduze kwe-y-axis yesigrafu. Imikhiqizo eminingi ibhala izincazelo ezihlanganisa ubuncane obungama-20 Hz (lows) kuya ku-20 kHz (phezulu), okuyinto ebhekene nokuzwa okujwayelekile kubantu. Ama Frequencies ngenhla nangaphansi kwalezo zinombolo zivame ukubhekwa njengempendulo ye- wideband frequency futhi ingabalulekile. Ukulinganisa kwama-decibel kubonisa ukushintsha okuphezulu (cabanga njengokubekezelelana noma umkhawulo wephutha) wezinga levolumu nokuthi idivayisi igcina kanjani ifanisha kusuka ephansi kunazo zonke kuya ezingeni eliphakeme kakhulu. Uhlu lwezintathu ze-decibels luvame kakhulu kulezi zimpendulo zokuphendula izimpendulo.
Kungani Ukuphendula Ngokuphindaphindiwe Kubalulekile?
Ungathatha izikhulumi ezimbili, ezingafani nezimpikiswano ezifanayo zemvamisa bese ugcina umculo ozwayo udlalwa ngokuhlukile ngakunye. Lokhu kungenzeka ngoba abakhiqizi ngezinye izikhathi basebenzisa ama-hardware / amadijithali amadizayini agcizelela izingxenyana ezithile zezimvamisa phezu kwabanye, hhayi ngokungafani nokuthi umuntu angenza kanjani izinguquko zamanothi nge-equalizer stereo . Inani lehlukahluka lichaza indlela umsindo ozophazamiseka ngayo ngokuchaneka.
Amaphuphu avame ukufuna imikhiqizo kanye nezingxenye ezinikeza impendulo yokungathathi hlangothi (noma ngokusondelana). Lokhu kubonisa isignesha "yezintambo" efana neyodwa egcina ubuhlobo obukhulu phakathi kwezinsimbi ezihlukahlukene, amazwi, kanye namathoni afanele ngaphandle kokugcizelela noma ukugcizelela noma yiliphi ibhulogi yamavolumu. Ngokuyinhloko, umculo ungakujabulela ngokwemvelo njengoba urekhodiwe ekuqaleni ngoba kunokushintshwa okuncane okuphoqelelwe ekukhiqizeni. Futhi uma umuntu ekhetha kanjalo, ukulungiswa okuqhubekayo nge-equalizer kuyindlela yokukhetha.
Kodwa wonke umuntu unelungelo lokuthandayo, izikhulumi eziningi kangaka, ama-headphone, nezinsimbi ezihlukahlukene zinikeza okuthandayo okuyingqayizivele ezintweni. Isibonelo, isignesha yomsindo "efana ne-v" ikhulisa amazinga aphansi nephezulu ngenkathi iqeda ububanzi obuphakathi. Lokhu kungabhena labo abalalele izinhlobo zomculo ze-EDM, i-pop, noma ze-hip-hop (ukubiza ezimbalwa) eziveza eziningi zebhasi futhi zihamba kancane. Isignesha yomsindo "omelele" ifana nesimo, kodwa ngama-frequencies ahlelwe ngezinga eliphansi kakhulu.
Eminye imikhiqizo iya eminye umsindo "wokuhlaziya" okhulisa ukuphakama (futhi ngezinye izikhathi ububanzi obuphakathi) ngenkathi eqeda ukuhlehla. Lokhu kungaba kuhle kulabo abazithola belalela izinhlobo zomculo zesi-classical noma zomculo, phakathi kwabanye. Iqoqo le-headphone "bassy" noma izikhulumi zizokwenza ngcono i-lows ngenkathi iqeda ukuphakama nobubanzi obuphakathi. Ngezinye izikhathi umkhiqizo ubonisa isignesha yomsindo oyimvelo yeyodwa noma ngaphezulu.
Impendulo jikelele yemvamisa iyasiza - kodwa akuyona into kuphela - ukuthola ukuthi umsindo uqondwa kanjani ngokuhlukana kwezinsimbi nemininingwane yezinto ezizimele. Imikhiqizo ebonisa ama-dips obukhali noma ama-spikes emafenjini angabangela ukulalela noma ukukhathala. Ijubane lapho amanothi adlala khona futhi ehlala isikhathi eside (okuvame ukubonakala njengokuhlasela nokubola) nakho kwenza umthelela omkhulu. Izinhlobo zomkhiqizo zibaluleke kakhulu, ngoba izingcingo kanye nezikhulumi ezinezimpendulo ezifanayo / ezifanayo zangezikhala zingaqhubeka zihlukile ngenxa yesikhala esidingekayo ukuze ngamunye abonise.
