Isophones, i.e. zais lub ntsiab lus ntawm kev kho

Isophonic curves yog cov yam ntxwv ntawm kev hnov ​​​​lus ntawm tib neeg lub suab, qhia tias qib siab npaum li cas (hauv decibels) yog qhov tsim nyog rau peb kom nkag siab txog tib lub suab nrov (qhia hauv phons) thoob plaws txhua qhov (ntawm txhua zaus).

Peb twb tau piav qhia ntau zaus (qhov tseeb, tsis yog txhua lub sijhawm) tias ib qho isophonic nkhaus tseem yog lub hauv paus tsis muaj zog rau kev txiav txim siab cov duab ntawm cov yam ntxwv ntawm lub suab nrov lossis lwm yam khoom siv suab lossis tag nrho cov kab ke. Nyob rau hauv qhov xwm txheej, peb kuj hnov ​​suab los ntawm "prism" ntawm isophonic nkhaus thiab tsis muaj leej twg qhia txog kev kho ntawm lub tshuab raj los yog cov cuab yeej ua si "nyob" thiab peb lub rooj sib hais. Peb ua qhov no nrog txhua lub suab hnov ​​hauv qhov xwm txheej, thiab qhov no yog ntuj tsim (nrog rau qhov tseeb tias qhov ntau ntawm peb lub rooj sib hais tseem txwv).

Txawm li cas los xij, ib qho teeb meem ntxiv yuav tsum raug coj mus rau hauv tus account - muaj ntau tshaj ib qho isophonic nkhaus, thiab peb tsis tau tham txog qhov sib txawv ntawm tib neeg. Rau peb txhua tus, qhov nkhaus isophonic tsis tas mus li, nws hloov nrog lub ntim theem: qhov ntsiag to peb mloog, ntau qhov liab qab ntawm cov qhab (tshwj xeeb tshaj yog qis zaus) pom ntawm qhov nkhaus, thiab yog li ntawd peb feem ntau mloog suab paj nruag ntawm tsev nyob ntsiag to dua suab paj nruag nyob (tshwj xeeb yog yav tsaus ntuj) ntim.

Sib npaug nrov nkhaus raws li ISO 226-2003 tus qauv tam sim no. Txhua qhov qhia tau hais tias yuav tsum muaj lub suab siab npaum li cas ntawm qhov ntau zaus los muab qhov kev xav ntawm qhov nrov nrov; Nws tau xav tias lub siab ntawm X dB ntawm qhov zaus ntawm 1 kHz txhais tau tias lub suab nrov ntawm X xov tooj. Piv txwv li, rau lub ntim ntawm 60 phons, koj xav tau lub siab ntawm 1 dB ntawm 60 kHz, thiab ntawm 100 Hz.

- twb 79 dB, thiab ntawm 10 kHz - 74 dB. Kev kho tau ntawm cov yam ntxwv hloov pauv ntawm cov khoom siv electroacoustic yog qhov tseeb.

vim qhov sib txawv ntawm cov nkhaus no, tshwj xeeb tshaj yog nyob rau hauv cheeb tsam tsawg zaus.

Txawm li cas los xij, qhov loj ntawm qhov kev kho no tsis tuaj yeem txiav txim siab meej, vim tias peb mloog cov suab paj nruag sib txawv ntawm qhov ntsiag to lossis nrov dua, thiab peb tus kheej isophonic curves kuj txawv ... Qhov tsim ntawm tus yam ntxwv, txawm tias nyob rau hauv cov kev taw qhia, twb muaj qee qhov kev txhawb nqa hauv. kev xav. Txawm li cas los xij, nrog tib txoj kev vam meej nws tuaj yeem xav tias nyob rau hauv qhov xwm txheej zoo tshaj plaws, hauv tsev, peb kuj mloog nrog lub suab nrov, zoo li "nyob" (txawm tias orchestras - lub ntsiab lus tsis yog lub suab nrov npaum li cas, tab sis lub suab nrov npaum li cas peb pom thaum lub sijhawm ua haujlwm. zaum ntawm lub rooj sib tham) ntawm qhov chaw, thiab tseem tsis tau stunned ces). Qhov no txhais tau hais tias cov yam ntxwv linear raug suav tias yog qhov zoo tshaj plaws (tsis muaj qhov sib txawv ntawm isophonic nkhaus rau "nyob" thiab mloog hauv tsev, yog li qhov kev kho tsis tsim nyog). Txij li thaum peb mloog ib zaug nrov, thiab qee zaum nyob ntsiag to, yog li hloov ntawm qhov sib txawv isophonic nkhaus, thiab cov yam ntxwv ntawm kev hais lus - linear, kho lossis xijpeem - raug teeb tsa "ib zaug thiab rau tag nrho", yog li ntawd, peb hnov ​​​​cov tib neeg hais lus ntau dhau. dua. txawv, nyob ntawm qhov ntim qib.

Feem ntau peb tsis paub txog cov khoom ntawm peb lub rooj sib hais, yog li peb muab cov kev hloov pauv no rau ... lub whims ntawm cov neeg hais lus thiab lub kaw lus. Kuv hnov ​​​​cov kev tshuaj xyuas txawm tias los ntawm cov kws paub txog audiophiles uas yws tias lawv cov neeg hais lus suab zoo thaum lawv ua si nrov txaus, tab sis thaum lawv mloog ntsiag to, tshwj xeeb tshaj yog nyob ntsiag to, cov ntses bass thaj tsam thiab treble attenuate disproportionately ntau ... Yog li lawv xav tias qhov no yog qhov tsis muaj. ntawm malfunction ntawm cov neeg hais lus lawv tus kheej nyob rau hauv no ntau yam. Nyob rau tib lub sijhawm, lawv tsis hloov lawv tus yam ntxwv txhua - peb lub rooj sib hais "faded". Yog tias peb kho cov neeg hais lus rau lub suab nrov thaum mloog zoo, ces thaum mloog nrov, peb hnov ​​​​ntau bass thiab treble. Yog li ntawd, cov neeg tsim qauv xaiv ntau hom "nruab nrab" ntawm cov yam ntxwv, feem ntau tsuas yog ua kom pom tseeb ntawm cov npoo ntawm cov sawb.

Raws li txoj cai, ib qho kev daws teeb meem zoo dua yog ua qhov kev kho ntawm qib hluav taws xob, qhov twg koj tuaj yeem kho qhov kev kho qhov tob mus rau theem (qhov no yog li cas classical loudness ua haujlwm), tab sis audiophiles tsis lees paub tag nrho cov kev kho, thov kom tsis txhob muaj qhov tsis zoo thiab naturalness. . Lub sijhawm no, lawv tuaj yeem ua haujlwm zoo li no, yog li tam sim no lawv yuav tsum txhawj xeeb vim li cas lub kaw lus suab qee zaum zoo thiab qee zaum tsis yog ...
