Pambuyo pa Volume Control - Mphamvu Yopambana, Kuponderezana, ndi Mutu
Zambiri zimapangitsa kuti muzimva bwino mu malo osungirako masewera olimbitsa thupi omwe ali ndi stereo kapena kunyumba. Kugwiritsa ntchito mphamvu ya voliyumu ndi njira yaikulu imene ambiri amapezera omvera bwino, koma sizingatheke kugwira ntchito yonse nthawi zonse. Mutu wamutu wamphamvu, kukula kwakukulu, ndi kupanikizika kwakukulu ndi zinthu zina zomwe zingathandizire kumvetsera chitonthozo.
Mutu Wamphamvu-Kodi Ndi Mphamvu Yowonjezera Kumeneko Pamene Mukulifuna?
Phokoso lodzaza chipinda, wolandila stereo kapena nyumba yoyang'anira nyumba ayenera kuika mphamvu zokwanira kwa okamba anu kuti muthe kumva zomwe zili. Komabe, popeza magulu amvekedwe amasintha nthawi zonse m'mavidiyo ndi mafilimu, wovomerezekayo ayenera kusintha mphamvu zake mofulumira mofulumira.
Mutu wamakono umatanthawuza kukhwima kwa wolandila stereo / kunyumba, kapena amplifier, kuti atulutse mphamvu pamtunda wapamwamba kwambiri kwa nthawi yayitali kuti akwaniritse mapiri a nyimbo kapena zovuta kwambiri m'mafilimu. Izi ndizofunikira makamaka panyumba ya zisudzo, kumene kusintha kwakukulu kumachitika panthawi ya filimu.
Chimutu cholimba chimayesedwa mu Decibels (dB) . Ngati wolandila / amplifier amatha kupititsa patsogolo mphamvu yake yopititsa patsogolo mphamvu yamtunduwu kwa kanthaŵi kochepa kuti akwaniritse mapiri, ali ndi 3db ya mutu wapamwamba. Komabe, kubwereza kabuku kowonjezera mphamvu sikukutanthawuza kuphatikizapo voliyumu. Pofuna kuwirikiza kawiri voliyumu kuchokera pa malo opatsidwa, wolandila / amplifier ayenera kuwonjezera mphamvu zake zowonjezera ndi gawo la 10.
Izi zikutanthawuza kuti ngati wolandila / amplifier akutulutsira watts 10 pa mfundo inayake ndipo kusintha kwadzidzidzi mu soundtrack kumafuna voliyumu voliyumu kwa nthawi yochepa, amplifier / receiver amafunika kutulutsa ma watt 100.
Kukhoza kumutu kwa mutu kumaphatikizidwa ku hardware ya wolandila kapena amplifier, ndipo sangathe kusintha. Choyenera, wolandila nyumba yosangalatsa ya nyumba yomwe ili ndi 3db kapena yowonjezera mutu wamtundu wambiri ndiye kuti mukuyembekezera. Izi zikhoza kuwonetsedwanso ndi chiwerengero cha mphoto ya mphamvu yomwe ikupezeka pamtunduwu - mwachitsanzo, ngati chiwerengero, kapena mphamvu, chiwerengero cha mphamvu chophatikizapo mphamvu, chiwerengero cha RMS, Continuous, kapena mphamvu ya FTC, ichi ndi chiwerengero cha 3db mutu wapamwamba.
Ngati simukudziwa momwe mphamvu yamagetsi ikugwirira ntchito, yang'anirani nkhani yathu momwe mphamvu yamagetsi imakhudzira mafilimu .
Zochita Zowonjezereka Zowonjezera ndi Loud
Muwotchi, kukula kwakukulu ndi chiŵerengero cha phokoso lalikulu kwambiri losasokonezeka limene limapangidwa mogwirizana ndi liwu lofewa kwambiri lomwe limamvekanso. 1dB ndi kusiyana kochepa kwambiri kwa mawu omwe khutu la munthu limatha kuzindikira. Kusiyanitsa pakati pa kanyang'onong'ono ndi kanyimbo ka loud rock (pamtunda womwewo kuchokera khutu lanu) ndi pafupifupi 100dB.
Izi zikutanthauza kuti kugwiritsa ntchito dB scale, concert rock ndi 10 bilioni kuposa kuposa kunong'oneza. Kwa nyimbo zolembedwera, CD yowonongeka imatha kubweretsa 100db yazitali, pamene LP imalemba pamwamba pa 70db.
Stereo, olandila kunyumba, ndi amplifiers omwe angathe kubzala ma CD kapena magwero ena omwe angapangitse kukula kwakukulu kwambiri ndi zofunika kwambiri.
Zoonadi, vuto limodzi ndi magwero a chitsime omwe amalembedwa ndi mtundu waukulu wa mawu ndi kuti "mtunda" pakati pa zofewa kwambiri ndi zomveka kwambiri zingakhale zokwiyitsa.
Mwachitsanzo, mu nyimbo zosakanikirana bwino, mawu amatha kuwoneka ngati akugwiritsidwa ntchito ndi zipangizo zamakono ndi mafilimu, nkhaniyo ikhoza kukhala yofewa kwambiri kuti imvetseke, pomwe phokoso lapadera sizingangokukhudzani koma ndi anansi anu.
Apa ndi pamene Kupsyinjika Kwamphamvu kumabwera.
Mphamvu Yowonjezera Mphamvu Yopambana
Kupanikizika kwamtunduwu sikukutanthauza mtundu wa mawonekedwe ophatikizira omwe amagwiritsidwa ntchito mu audio audio (ganizirani MP3). M'malo mwake, kupanikizika kwakukulu ndi chida chomwe chimalola womvetsera kuti asinthe mgwirizano pakati pa mbali zomveka kwambiri za soundtrack ndi zovuta za nyimbo ya soundtrack pamene mukusewera CD, DVD, Blu-ray Disc, kapena mtundu wina wa mafayilo.
Mwachitsanzo, ngati mutapeza kuti ziphuphu kapena zinthu zina za soundtrack ndi zokweza kwambiri ndipo nkhaniyo imakhala yofewa kwambiri, mungafune kuchepetsa kukula kwazomwe zilipo mu soundtrack. Kuchita zimenezi kumapangitsa kuti ziphuphu zisamveka mokweza, komabe kukambirana kumveka bwino. Izi zimapangitsa kuti phokoso lonse likhale lothandiza kwambiri, makamaka pamene likusewera CD, DVD, kapena Blu-ray Disc pamunsi wotsika.
Pogwiritsa ntchito zipangizo zamakono zogwiritsira ntchito zipinda zamakono, kuchuluka kwa kupanikizika kwakukulu kumasinthidwa pogwiritsa ntchito njira yosungirako zinthu zomwe zingatchulidwe kupanikizika kwakukulu, kapena ku DRC chabe.
Zina zofanana ndi dzina lachitsulo loyendetsa kupanikizika dongosolo ndi DTS TruVolume, Dolby Volume, Zvox Accuvoice, ndi Audyssey Dynamic Volume. Kuphatikizanso, njira zina zoyendetsera kayendedwe kazomwe zingagwire ntchito zosiyanasiyana (monga nthawi yosintha njira pa TV kotero kuti njira zonsezi zili pamlingo womwewo, kapena kugulitsa malonda akuluakulu mu pulogalamu ya TV).
Mfundo Yofunika Kwambiri
Mutu wamutu wamphamvu, kukula kwakukulu, ndi kupanikizika kwakukulu ndi zinthu zofunika zomwe zimakhudza mtundu wa voliyumu yomwe ilipo pakumvetsera. Ngati kusintha masitepewa sikukonza mavuto omwe mukukumana nawo, ganizirani kuyang'ana pa zinthu zina monga kusokoneza ndi chipinda chamakono .
