01

Yuav txiav txim li cas ntawm qhov koj hnov ​​lus?

Koj yuav tsum txiav txim rau koj qhov tsis hnov ​​lus raws koj qhov txiaj ntsig kev hnov ​​lus nruab nrab. Qhov nruab nrab ntawm lub rooj sib hais plaub yog dab tsi?

Qib ntawm tsis hnov ​​lus zoo

Daim ntawv qhia txog lub rooj sib hais

Raws li pom hauv daim duab saum toj no, kab ntsuab ntsuab qhia pom qhov ntau ntawm cov hnov ​​lus, uas yog, nruab nrab hnov ​​≤25dBQhov ntawd yog qhov tau hnov. Nruab nrab ntawm lub rooj sib hais pib25dBQhov saum toj no yog hnov ​​lus tsis zoo.

Abscissa: Sawv cev rau ntau zaus ntawm lub suab. Cov paib suab nrov uas koj hnov ​​thaum koj mloog lub suab sib txawv vim hais tias ntawm cov ntau zaus.

Tus kab ke: sawv cev ntawm lub suab nrov ntawm lub suab, uas yog, kev txiav txim siab tus nqi

Tom qab ntawv koj lub rooj sib hais raws qhov nruab nrab yog500,1000,2000,4000HzQhov tawm ntawm cov coj coj los sib cais tau muab faib4Cov. Nws yog:

Nruab nrab lub rooj sib hais pib=(500HzSib nug tus nqi+ 1000HzSib nug tus nqi+ 2000HzSib nug tus nqi+ 4000HzTus nqi raug)/4

piv txwv

Noj cov duab no ua piv txwv, qhov ntsuas nruab nrab ntawm qhov sib hais=(50 55 + + + 50 55 XNUMX)/4 = 52.5dB

Tom qab suav qhov nruab nrab ntawm qhov ntsuas lub rooj sib hais, qhov ntsuas ntawm kev hnov ​​lus yuav raug txiav txim. Nws tuaj yeem raug txiav txim raws li cov lus saum toj saud, tom qab ntawv koj lub rooj sib hais tsis zoo pes tsawg.

Yuav txiav txim li cas ntawm qhov hnov ​​lus?

Ntawv Hlob

Hauv cov kab xev li hais hauv daim duab, daim duab pob ntseg hnov ​​pob ntseg sab xis yog sab laug, cim rau xim liab, thiab sab laug pob ntseg hnov ​​sab sab xis, cim hauv xiav.

Ob txoj kab yog kos rau hauv txhua daim duab, sawv cev ntawm cov huab cua hauv kev txiav txim siab (ntsuas los ntawm kev coj los ntsuas lub ntsej muag roj) thiab lub pob txha los ntawm kev ntsuas (ntsuas los ntawm lub pob txha ua pob ntseg pob ntseg).

Cua cua kev ua cua nkhaus: qhov nkhaus liab ntawm sab xis pob ntseg yog tsim los ntawm lub voj voog ○ lossis △, thiab lub pob ntseg sab laug yog ua los ntawm rab rawgXLos yog xiav xiav nkhaus uas txuas nrog.

Pob txha conduction nkhaus: pob ntseg sab xis yog ua los ntawm<Or[Lub cim tau txuas rau hauv txoj kab liab, sab laug pob ntseg yog ua los ntawm>Or]Ib txoj kab xiav xiav txuas nrog los ntawm cim.

Lub pob txha conduction nkhaus feem ntau nyob saum cov cua conduction nkhaus.

Kev txiav txim qhov tsis zoo ntawm pob ntseg

Muaj kev sib luag lag ntseg

Pob txha conduction nkhaus ntawm ≤25dBTsis pub dhau ntawm qhov ntau, cov cua conduction curve faib loj dua25dBTsis yog nyob rau hauv ib txwm muaj.

Qhov chaw ntawm lub qhov txhab feem ntau yog hauv pob ntseg sab nraud thiab nruab nrab.

Sensorineural lag ntseg

Ob leeg lub pob txha conduction curve thiab cua conduction nkhaus yog loj dua25dBTsis yog nyob rau hauv thaj tsam li qub, thiab qhov kev ncua deb ntawm ob qhov nkhaus yog tsawg dua10dB.

Qhov chaw ntawm lub qhov txhab feem ntau yog nyob rau sab hauv pob ntseg (cochlear lossis posterior cranial hlab ntsha).

Ntsig txog lag ntseg

Ob leeg lub pob txha conduction curve thiab cua conduction nkhaus yog loj dua25dBTsis yog nyob rau hauv qhov muaj peev xwm ib txwm, thiab qhov kev ncua deb ntawm ob txoj kab nkhaus yog ntau dua10dB.

Qhov chaw ntawm lub qhov txhab muaj ntau dua ntawm pob ntseg sab hauv, pob ntseg nruab nrab thiab mob pob ntseg sab hauv ua rau hnov ​​lus tsis zoo.

Daim duab qhia txiv tsawb duab ntxoov ntxoo hauv daim kab xev yog dab tsi?

Daim ntawv qhia txog lub rooj sib hais

Cov duab ntxoo zoo li lub tsawb zoo li no hu ua daim duab qhia txog nplooj tsawb, uas yog tib neeg ib txwm hnov ​​thaj chaw hais lus. Yog tias peb lub pob ntseg sib luag faib rau hauv cov kab hais lus tsawb, nws ua pov thawj tias peb tuaj yeem hnov ​​feem ntau ntawm cov hais lus.

Koj puas paub qhov ntawd?
