Zambiri zamagetsi zogula zimagulidwa zimakhala ndi mayankhidwe afupipafupi omwe amadziwika ngati chimodzi mwazofotokozera. Mayankho afupipafupi amapezeka kwa okamba, mafoni, mafoni, mafilimu, ovomerezeka, CD / DVD / osewera. mafoni osewera / zipangizo, ndi chiwerengero china cha zipangizo zina zamagetsi kapena zigawo zina . Ena opanga zinthu monga zonse zomwe zimakhala ndifupipafupi, koma manambalawa amangofotokoza mbali imodzi chabe ya nkhaniyi osati chizindikiro cha khalidwe labwino. Maselo a headphones angayambe kufotokoza kawirikawiri yankho la ma Hz-34 kHz +/- 3 dB, koma kodi kwenikweni amatanthauza chiyani?
Kodi Nthawi Zonse Zimayankhidwa Bwanji?
Kuyankha kwafupipafupi, komwe kawirikawiri kumawonekera pa grafu / tchati ngati mphira, limafotokoza mmene chipangizo chimayendera phokoso pamtundu uliwonse. Mafelemu amawerengedwa mu hertz (Hz) pambali ya x-axis ya grafu, ndi msinkhu wopanikizika (SPL) womwe umayesedwa mu decibels (dB) pambali ya graph y-axis. Zambiri zimatulutsa zolemba zomwe zimaphatikizapo 20 Hz (lows) kufika 20 kHz (highs), zomwe ndizovomerezeka kumvetsera kwa anthu. Maulendo pamwambapa ndi pansipa manambalawa amatchulidwa kuti broadband frequency response ndipo angakhalenso ofunika. Kuyeza kwa ma decibel kumasonyeza kusiyana kwakukulu (kuganiza ngati ngati kulekerera kapena kupitirira kwa mphulupulu) ya voliyumu yapamwamba ndi momwe kachipangizo kamakhalabe yunifolomu kuchokera pansi pazitali mpaka kufika pamwamba kwambiri. Mitundu itatu ya decibel imakhala yowonongeka pamayendedwe oterewa.
Chifukwa Chiyani Frequency Response Ndi Yofunika?
Mungathe kutenga awiri omwe sali ofanana omwe amalankhula momveka bwino ndikumaliza nyimbo zomwe zimamvetsera mosiyana. Izi ndi zotheka chifukwa opanga nthawi zina amagwiritsa ntchito hardware / mapulogalamu a mapulogalamu omwe amatsindika mafupipafupi ambiri pazinthu zina, osati mosiyana ndi momwe munthu angapangire kusintha kwake ndi stereo equalizer . Kuchuluka kwa kusiyana kumatanthauzira momwe mawuwo adzakhudzidwire mwachindunji.
Otsenga nthawi zambiri amafuna mankhwala ndi zigawo zikuluzikulu zomwe zimapereka ndewu (kapena pafupi kwambiri) kuyankha kwafupipafupi. Izi zimapangitsa kuti "signature" signature sonicic signature (saic signature sonic signature) yomwe imasunga mgwirizano waukulu pakati pa zida zosiyanasiyana, mawu, ndi mauthenga othandiza popanda-kapena kugogomezera pafupipafupi band (s). Zofunikira, nyimbo zingathe kusangalatsidwa mwachibadwa monga zolembedwera kale popeza palibe kusintha kovuta kuti abwerere. Ndipo ngati wina amusankha, kuyendetsa mofanana ndi zofanana ndizomwe mungakonde.
Koma aliyense ali ndi ufulu wokonda yekha, okamba nkhani ambiri, makompyuta, ndi zigawo zikuluzikulu amapereka zofuna zawo zapadera pazinthu. Mwachitsanzo, siginecha ya "v-shaped" imawongolera maulendo apansi ndi apamwamba pamene akuchotsa pakatikati. Izi zingakhudze anthu omwe amamvetsera mitundu ya nyimbo za EDM, pop, kapena hip-hop (kutchula angapo) zomwe zimafotokoza zambiri komanso zimayenda bwino. Chizindikiro chokhala ngati "choboola" chimafanana mofanana, koma ndifupipafupi zimasinthidwa kufika pang'onopang'ono.
Zina mwazinthu zimapanganso zowonjezera zowonjezera "zomveka" zomwe zimalimbikitsa zam'mwamba (ndi nthawi zina pakatikati) pamene zimasokoneza. Izi zikhoza kukhala zabwino kwa iwo amene amadzimvera okha kumvetsera nyimbo zachikhalidwe kapena zowerengeka, pakati pa ena. Masewera a "bassy" kapena oyankhula angayambe kulimbikitsanso pamene akuchotsa pamwamba ndi pakati. Nthaŵi zina mankhwala amasonyeza siginecha ya mawu yomwe ndi wosakanizidwa wa mitundu imodzi kapena iwiri.
Kuyankha kwafupipafupi kumawathandiza - koma sizomwe zimapangidwira - kudziwa momwe mawu amveketsere ponena za kulekana kwa zida ndi tsatanetsatane wa zinthu zina. Mitundu yomwe imapanga ma divi kapena ma spikes akuthwa mufupipafupi ingayambitse vuto lakumvetsera kapena kutopa. Kufulumira kumene masewero a masewera ndi nthawi yayitali (omwe nthawi zambiri amadziwika monga kuukira ndi kuwonongeka) imathandizanso kwambiri pazochitikirazo. Mitundu ya malonda ndi yofunika kwambiri, popeza matelofoni ndi okamba omwe ali ndi mayankho ofanana / ofanana omwe amatha kuwoneka angakhale osiyana chifukwa cha malo oyenera kuti aliyense afotokoze.
