Txhais thiab soj ntsuam kev cuam tshuam los ntawm otoacoustic emissions

01

Lus Txhais: Otoacoustic emission (Otoacoustic emission, OAE) yog lub zog tsim tawm hauv cochlea uas tso rau hauv qhov txuas sab nraud los ntawm cov kav dej ossicular saw thiab lub tympanic membrane. Nws qhia tau hais tias lub cochlea tsis tsuas yog xav txog lub suab lub suab, tab sis kuj muaj cov haujlwm ntawm kev ua kom muaj suab nrov lub zog.

Kev faib tawm: Raws li seb puas muaj lub zog ntsuas sab nraud, nws tau muab faib ua:

Lwj paug pa hluav taws xob otoacousticTxhawj otoacoustic emission, SOAE) yog hais txog lub suab cim uas kaw nyob rau hauv cov kav dej sab nraud los ntawm cochlea tsis muaj qhov stimuli sab nraud.

Evoked otoacoustic emissionsEvoked otoacoustic emission, EOAE) hais txog qhov tso tawm ntawm lub zog acoustic tsim tawm los ntawm cochlea nyob rau hauv qhov sib txawv sab nraud stimuli.

Kev tsim hluav taws xob otoacoustic emissions tuaj yeem muab faib ntxiv ua plaub pawg: ntu acoustically los vim otoacoustic emissions (TSODistortion khoom otoacoustic emission (DPOAE), txhawb kev tawm zaus otoacoustic emissions (SFOAE), xa hluav taws xob otoacoustic emissions (EEOAE).

Ob hom kev siv ntau hauv chaw kho mob yogDPOAE,TSO.

DPOAE: hais txog kev xa hluav taws xob otoacoustic emission uas ua los ntawm ob qho pib lub suab ntshiab stimuli muaj qhov ntsuas thiab qhov sib piv;

TSO: hais txog lub suab acoustic lub zog tso tawm los ntawm cochlea tom qab muaj kev hloov pauv sai sai thiab tso tawm ib hom tom qab ib lub sijhawm. Daim ntawv yog txiav txim siab los ntawm cov yam ntxwv ntawm tus stimuli.

Kev txhais lus:

DPOAE:

1, cov tshuaj tiv thaiv amplitude tshaj qhov nrov hauv pem teb3dBThiab saum toj no, piv txwv liSNR3dB;

2, ntsuas tus nqi ≥60%, ntawd ces yog peb lossis ntau tshaj tsib qhov ntsuas raws qhov raug muab tau los;

3,DP≥ ≥ -10dB.

Qhov saum toj no qhia tau hais tias tso cai (PASS), txwv tsis pub nws ua tsis tau tejyam (LUS TEB).

TSO:

1, cov tshuaj tiv thaiv amplitude tshaj qhov nrov hauv pem teb3dBThiab saum toj no, piv txwv liSNR3dB;

2, tag nrho cov kev sib txheeb ntawm cov nthuam dej ≥70%.

Qhov saum toj no qhia tau hais tias tso cai (PASS), txwv tsis pub nws ua tsis tau tejyam (LUS TEB).

Cov chaw soj ntsuam daim ntawv thov:

Kev soj ntsuam kuaj lub ntsej muag rau cov menyuam mos: Otoacoustic emission yog qhov yooj yim, nrawm, tsis cuam tshuam, yooj yim rau kev khiav lag luam, rhiab, thiab lwm yam Yog li ntawd, qhov kev ntsuam xyuas otoacoustic emission tau siv hauv chaw kho mob raws li kev ntsuam xyuas kev hnov ​​lus rau cov menyuam mos;

Kev ntsuas hauv ib cheeb tsam kuaj pom ntawm cov mob cochlear: Yog tias tsis muaj qhov txhab nyob tom hauv ntej ntawm cochlea, nws tuaj yeem ua rau otoacoustic emission, uas ua pov thawj tias cochlea yog dab tsi; yog tias tsis muaj qhov txhab nyob tom hauv ntej ntawm lub cochlea, nws tsis tuaj yeem ua rau otoacoustic emission, uas ua pov thawj tias qhov cochlea yuav muaj qhov mob txhab, vim tias qee tus neeg ib txwm tsis tuaj yeem ua;

Kev kuaj pom ntawm qhov mob tom qab cochlear: Yog hais tias tus neeg mob yog lub suab hnov ​​lub suab hnov ​​tsis hnov ​​lus, qhov hluav taws xob otoacoustic yuav ua rau pom lub qhov txhab tom qab cochlear; yog tias tus neeg mob yog lub suab hnov ​​lub suab hnov ​​lub suab tsis hnov, qhov otoacoustic emission tsis tuaj yeem tshwm sim, uas ua pov thawj tias lub cochlea yuav muaj qhov mob tab sis tsis tuaj yeem tshem qwj Tom qab kev mob;

Kev kuaj mob ntawm qhov chaw mob txhab: Otoacoustic emissions muaj qhov ntsej muag tshwj xeeb. Yog tias ob tog tuaj yeem tsim hluav taws xob otoacoustic emissions, lub otoacoustic emission tus nqi yuav raug attenuated tom qab rov qab sab tau muab ib qho kev txhawb nqa acoustic. Yog tias tsis muaj qhov ua tau zoo, hauv lub hauv nruab nrab lub paj hlwb yuav muaj qhov txhab.
