Imvamisa okuphansi nekhwalithi isithuthukisi

Bass - umqondo kuhlanganise ibanga umsindo ezwakalayo nezindlebe zomuntu. Ngokwesilinganiso kuwukuthi basukela 20 Hz kuya ku-20 kHz. Audiogram, enquma ikhono bayosibona embundwini engezansi imvamisa ngamunye, babe siqu izici zabo ngamunye, ukuze sikwazi ukukhuluma mayelana isilinganiso ukuzwa kwezibalo. Ngokuvamile, amaza ngezansi 40 Hz nangaphezulu 16 kilohertz kunalokho ukuthonya phezu umbala umsindo ngaphandle wazizwa uqobo.

Ububanzi sokuzala bese bedlulisela imishini ihlukile, ezahlukene ngakho nezimfuneko ke. Isibonelo, ucingo njalo eveza imvamisa umsindo kusukela 200 Hz ukuze 3 kHz, futhi lokhu kwanele ukuqaqa ngokucacile wonke amazwi tube at komunye umkhawulo noma, esimweni ngokusebenzisa ama-apharathasi mobile i-microphone. Kuyefana nasendleleni okuthiwa "izinsimbi" - Izikhulumi Translational. Nokho, maqondana ibhendi yokuvama lidlule ejwayelekile emhlabeni, owawuthi ekilasini imishini Hi-Fi kufanele ibe yokuhlela ibhendi yokuvama ka-20 kuya ku 20000 Hz futhi ebanzi.

ephansi imvamisa amplifier asetshenziswa kabanzi njengengxenye kagesi amadivayisi ahlukahlukene ezimbonini nasemizini, njengoba umsakazo ehlukile. Ziyakwazi kwezama-computer, amathelevishini, imisakazo, ama-CD-player, ratsiyah, omakhalekhukhwini, iziteshi ucingo nabanye abaningi ajwayelekile kithi izinto.

I izici eyinhloko amplifier zimi kanje:

- amandla lokukhipha. Namuhla kubhekwa ngendlela ehlukile. Ngokwesibonelo, ukuze udale at lwemibono maloponimayuschego wobuntu ivolumu ephezulu, okuyinto uyokwazi ukujabulela, phezu iphakheji umamukeli noma amplifier, ungabona ezinkulukazi ngokuphelele izinombolo enamadijithi amane imakwe «PMPO». Lezi zincwadi kufanele ngokomthetho kusho umthwalo isiqongo, okuyinto anganikeza imishini short alalelwayo. Amandla angempela - iyona ubukhulu iqinisekisa undistorted wave sine ifomu at a imvamisa of 1,000 Hz zolimo ukuze amplifier.

- Ukuhlanekezela - Inani ekuboniseni kangakanani imisindo ephansi ngefomu yabo esigabeni okukhipha ihlukile isignali okufakwayo. Cishe lena yiyona ipharamitha ezibaluleke kakhulu, ukhuluma ngani wenza kanjani kahle futhi egcizelele ongaphakeme-imvamisa amplifier.

- ububanzi Dynamic. Lesi sici kubalulekile kakhulu imishini ephezulu yokukhulisa izwi, inikeza umqondo wokuthi kuqondile igrafu inzuzo. Ngamanye amazwi, ibanga ngokwanele ububanzi ashukumisayo uzobe undistorted zonke imvamisa low, kungakhathaliseki izinga labo. Futhi ethule kakhulu, futhi nomsindo omkhulu kuzodlalwa enokwethenjelwa. Lokhu izinga kuyisici sobuntu tube Amps.

- Imvamisa impendulo. On kwathiwa okukhulunywe ngaye esihlokweni, ungakwazi ukwengeza isici ke njengoba iyunifomu. Kahle kahle, kuba ngqo umugqa parallel esikalini abscissa nge imvamisa lonke uhla yokusebenza.

Lezi nemingcele kuchazwe izinga ngawo imisindo ephansi kuthiwa yakhiqizwa classical imishini yokukhulisa izwi. Kwezinye yesimanje zasendlini amasampula zomculo imvamisa izici uhlanekezelwe ukudala imiphumela imfashini ezifana izingxenye bass isithuthukisi noma imvamisa ultrahigh, okuyinto has a nomphumela olimazayo ukuzwa nobuchopho ngamabomu.
