Zvimwe zvemashoko edu anokosha ndeyekwanisi kuona uye kunzwa. Tine nzeve dzedu, tinogona kuona kuchinja kwemazwi kubva kunonyoroveveveveveka kunyorera kune inzwi guru rinodonha.
Mazwi Atinonzwa
Zvisinei, kunze kwekukwanisa kunzwa, ndiyo nzira yatinonzwa.
Inzwi (iyo mafungu anotenderera mumhepo, mvura, kana imwe miviri yakabatana) inosvika kune chikamu chekunze chenzeve dzedu, chinoshandiswa kuburikidza nemugero wekunzwa kusvika kudivi.
Chii Chinojekesa Kuda Kwekutinhira
Inzwi rukuru sei rinotsanangurwa nehuzhinji hwezvinhu, izvo zvinosanganisira kusanganiswa kwehuwandu hwemhepo inosvika munzeve kubva kune anotanga kurira, uye kureba kwe nzeve dzedu kubva pakutangira kwezwi.
The Decibel Scale
Kuti adudzire kutambira kunzwika, chiyero, chinozivikanwa sekuti decibels, chakasikwa.
Nzeve dzedu dzinoona kuchinja kwehuwandu mune imwe nzira isina kufanana. A decibel ishoko relogarithmic yezwi guru. Kusiyana kwe 1 decibel kunonzwisiswa sekunoshanduka kushandiswa kwehuwandu, 3 decibel ishanduko inonzwisisika, uye ma decibel 10 anonzwisiswa nemuteereri seanopetwa kaviri. Zvibvumirano zvinosarudzwa netsamba: dB.
0 dB ndiro chikumbaridzo chekunzwa - Mamwe mienzaniso inosanganisira:
- Whisper: 15-25 dB
- Mhere-mhere yepamusoro: inenge 35 dB
- Musha wakajairika kana ofisi iri kumashure: 40-60 dB
- Kazhinji kutaura izwi izwi: 65-70 dB
- Mhedziso yemakumbo: 105 dB
- Rarama Rwiyo rwenhare: 120 dB +
- Pain Threshold: 130 dB
- Jet ndege: 140-180 dB
Nzira yekuti Decibel Scale Inoshandiswa Sei
Chikamu che decibel chinoshandiswa kumamiriro emitambo yemusha mumutambo unotevera:
Pamusoro pemagetsi, decibels inoratidza chiyero chehuwandu hunoti hunoita simba kuti huve nehuwandu hunobuda huwandu hwehutano. Zvisinei, kune chinhu chinonakidza kutaura.
Kana imwe yekumhanyisa kana kuti inogamuchirwa ichikwirirana kaviri seimwe, iwe unoda katatu kuwedzerwa mvura. A Receiver neWPC 100 inogona kaviri yehuwandu hwehuwandu hweWPC amp. A receiver ne 100 WPC inoda kuva 1000 WPC inopetwa kaviri. Kuti uwane mamwe mashoko pamusoro pekuti kukura kwemasimba ekugadzirisa zvinokanganisa sei kushanda, verenga nyaya yacho: Kunzwisisa Magetsi Ezvokubuda Kwemashoko .
Mune shanduro yakanyatsoshandiswa, ma-decibel anoshandiswa zvakare maererano nezwi rinokonzerwa nehuwandu hwemakwikwi uye subwoofers pane dzimwe nguva, pahuwandu hwehuwandu hwemazwi. Semuenzaniso, mukurukuri angave ane simba rekubudisa huwandu hwemaawa 20 Hz kusvika ku20kHz, asi pamagetsi akaderera pasi pe 80 Hz, inzwi rehuwandu hunogona kuve - 3dB pasi maererano nehuwandu hwehuwandu. Ichi ndechokuti mamwe masimba anobudiswa anowanikwa pasi pfupi kuti abudise izwi rimwechete.
Uyewo, dB chikoro chinoshandiswa kumutsananguro wehuwandu hwehuwandu hwehutano hunokwanisa huri mukurukuri kana uchinge uchitaura izwi rinotakurwa nerimwe watt simba.
Semuenzaniso, mukurukuri anogona kubudisa 90 dB kana yepamusoro yezwi rinogadzirwa kana adyirwa imwe-watt signal rekuonekwa inove nekunzwisisa .
Zvisinei, kungoita kuti mukurukuri ave nokunzwisisa kwakanaka hazviiti kuti aone kana iri "yakanaka" hurukuro. Mukurukuri anoda ruzivo rukuru kuti abudise inzwi rinongoratidzira huwandu hwesimba rinodiwa kuti mukurukuri ataure inzwi rinonzwika. Zvimwe zvinhu, kusanganisira nguva zhinji, kupesana, simba rekutonga, uye kugadzira hurukuro, zvinokosha zvakare.
Mukuwedzera, nokuda kwevhidhiyo majekitori, chidimbu che decibel chinoshandiswawo kuti chiyero chekuti inzwi rakadini rinobudiswa nehutori hunotonhora. Semuenzaniso, kana vhidhiyo projector ine chikamu chekunzwika kwema20dB kana kuti pasi, iyo inonzi inonyarara zvikuru. Kunze kwekuti iwe ugere pedyo, iwe haufaniri kukwanisa kunzwa fan - uye kana ukadaro, haufaniri kutsausa.decibels
Nzira Yokufananidza Dhaibhodhi
Iye zvino zvaunofunga kuti chii chinonzi decibels uye kuti chinopindira sei mumimhanzi neimba yemitambo inoteerera ruzivo, mubvunzo ndewokuti "Ungavayera sei?".
Kune vashandi, imwe nzira-decibels inogona kuyerwa ndeyokushandisa mifananidzo inotaridzika yemamita (yakafanana neyo inoratidzwa mumufananidzo uri pamusoro apa unowanikwa munyaya ino.
Sezvo vazhinji veimba yemitambo vakagamuchira vakagadzira-mu test tone jenereta, unogona kushandisa toni idzodzo kuti uone iyo yakagadzirirwa chidimbu chekudzivirira kune imwe hurukuro inopiwa kuwandisa kwehuwandu hwemazinga. Kana uchinge waona chimiro che decibel chinogadzirwa nemukurukuri wega wega, iwe unogona kugadzirisa mumwe wako mukurukuri wevheji yemavhareji kuitira kuti mutauri wehutano wese uite. Apo vatauriri vako vose vanyoresa chiyero chimwechete che decibel pane imwe yehuwandu yehuwandu, ipapo kuterera kwako kwakanyatsoteerera kuchave kwakaenzana.
