Zinthu ziwiri zofunika kwambiri ndizoona komanso kumva. Ndi makutu athu, tikhoza kuzindikira kusintha kwa kusintha kwakumveka kosavuta kwambiri kumveka kumveka kwambiri.
Momwe Timamvera
Komabe, kuwonjezera pa luso lomvetsera, ndi momwe timamvera.
Mkokomo (yomwe ndi mafunde omwe amayendayenda mumlengalenga, madzi, kapena sing'anga yamtundu wina) amafikira mbali yakunja ya makutu athu, omwe amawongolera kudzera mu ngalande ya khutu kupita kumtunda.
Chimene Chimatsimikizira Kuwala Kwake
Kumveka kwakukulu kotere kumatsimikiziridwa ndi zifukwa zambiri, zomwe zimaphatikizapo kuchuluka kwa mpweya umene ukufika pakumva kuchokera kwa amene anayambitsa phokoso, komanso kutalika kwa makutu athu kuchokera ku chiyambi cha mawu.
The Decibel Scale
Kutanthauzira kumveka kwa mawu, pulogalamu, yotchedwa decibels, inalengedwa.
Makutu athu amadziwa kusintha kwa voliyumu mu njira yosagwirizana. A decibel ndi logarithmic scale loudness. Kusiyanitsa kwa 1 decibel kumawoneka ngati kusintha kosachepera kwa voliyumu, ma decibel 3 ndi kusintha kosasintha, ndipo ma decibel 10 amavomerezedwa ndi omvera ngati voliyumu ya voliyumu. Decibels amadziwika ndi makalata: dB.
0 dB ndilo khomo la kumva - Zitsanzo zina ndizo:
- Kunong'oneza: 15-25 dB
- Phokoso lakumbuyo: pafupifupi 35 dB
- Nyumba yachizolowezi kapena ofesi ya ofesi: 40-60 dB
- Liwu loyankhula mwachizolowezi: 65-70 dB
- Mapeto a mimba: 105 dB
- Nyimbo ya Rock Rock: 120 dB +
- Threshold yapweteka: 130 dB
- Jet ndege: 140-180 dB
Momwe Dothi la Decibel Limagwiritsidwira Ntchito
Dothi la decibel likugwiritsidwa ntchito ku malo owonetserako nyumba potsatira mafashoni otsatirawa:
Kwa ma amplifiers, decibels amasonyeza muyeso wa mphamvu zomwe zimatengera kuti apange phokoso lenileni lomwe limatuluka. Komabe, pali chinthu chochititsa chidwi kuwonetsa.
Kuti amphamvu kapena wolandila amve mokweza mobwerezabwereza monga wina, mukufunikira nthawi zambiri zowonjezereka. Wothandizidwa ndi WPC 100 akhoza kuwirikiza kawiri mlingo wa 10 WPC amp. Wolandira ndi 100 WPC ayenera kukhala 1,000 WPC kukhala kawiri mokweza. Kuti mudziwe zambiri za momwe mphamvu zamagetsi zimakhudzidwira ntchito, werengani nkhaniyi: Kumvetsetsa Mafotokozedwe Opambitsira Mphamvu .
Pogwiritsiridwa ntchito kwambiri, ma decibel amagwiritsidwanso ntchito pokhudzana ndi phokoso lopangidwa ndi makanema ndi subwoofers pafupipafupi, pamagulu apadera. Mwachitsanzo, wokamba nkhani angakhale ndi mphamvu yotulutsa maola 20 Hz kufika 20kHz, koma pafupipafupi ndi 80 Hz, phokoso lomveka bwino likhoza kukhala - 3dB pansi pa voti yotuluka. Izi ndi chifukwa chakuti mphamvu zowonjezera zowonjezera zimafunika pafupipafupi kuti zikhale ndi mlingo womwewo.
Ndiponso, mlingo wa dB umagwiritsidwa ntchito pa liwu lomveka bwino lomwe limakhala lokhala ndi wokamba nkhani pamene wadyetsa kamvedwe kamene kali ndi mphamvu imodzi ya mphamvu.
Mwachitsanzo, wokamba nkhani amene angapange 90 dB kapena kupitirira kwa voliyumu polankhula pamene akudyetsa chizindikiro cha watt imodzi amalingalira kuti ali ndi chidwi .
Komabe, chifukwa choti wokamba nkhani ali ndi mphamvu zowona sadziwa bwinobwino ngati ali wokamba bwino. Wokamba nkhani yemwe amafunikira mphamvu yowonjezera kutulutsa mawu amangosonyeza kuchuluka kwa mphamvu yofunikira kuti wokamba nkhani apange phokoso lomveka. Zinthu zina, kuphatikizapo nthawi zambiri, kupotoza, kugwiritsira ntchito mphamvu, ndi kumanga okamba, ndizofunikanso.
Kuonjezerapo, kwa opanga mavidiyo, decibel scale imagwiritsidwanso ntchito kuti muyese kuchuluka kwa mawu omwe amawotcha. Mwachitsanzo, ngati pulojekiti yamakono ili ndi phokoso la phokoso la 20dB kapena zochepa, izo zimatengedwa kukhala chete. Pokhapokha ngati mutakhala pafupi, simuyenera kumvetsera fanaku - ndipo ngati mutero, sikuyenera kusokoneza.decibels
Mmene Mungayankhire Decibels
Tsopano kuti muli ndi lingaliro lomwe ma decibel ali ndi momwe amalingalira muzochitikira nyimbo ndi kumvetsera kumvetsera kunyumba, funso ndilo "Kodi mungawayeze bwanji?".
Kwa ogula, njira imodzi yokha ya ma decibel ingakhoze kuyesedwa ndi kugwiritsa ntchito mamita ojambulidwa (ngati ofanana ndi omwe akuwonetsedwa pamwambapa chithunzichi.
Popeza anthu ambiri opanga masewero a kunyumba amamanga-mu jenereta zowunikira, mungagwiritse ntchito matanthwewa kuti muzindikire mlingo wa decibel wokhala ndi wolankhulira aliyense wopatsidwa mpikisano. Mutangodziŵa mlingo wa decibel wopangidwa ndi wokamba nkhani aliyense, ndiye mukhoza kusintha ndondomeko yanu ya voliyumu ya wokamba aliyense kuti dongosolo lonse la oyankhula lifanane. Pamene okamba anu onse alembetsa mlingo womwewo wa decibel pamtundu wopambana woperekedwa, ndiye kumvetsetsa kwanu kumvetsera kumakhala koyenera.
