ITE Hnov Amplifier

Qhuav Taw Qhia

ITE Hearing Amplifier (XB-102)

Piv nrog ITC hnov ​​suab amplifier thiab CIC hnov ​​suab amplifier,

tusqhov zoontawm ITE hnov ​​suab amplifier yog:

* Haum rau qhov tsis hnov ​​​​lus ntau yog qhov dav, lub zog tso zis loj;
* Nws yog ib qho yooj yim rau nruab ob lub microphones, suab xaiv coil thiab lwm yam khoom siv;
* Nws yooj yim dua los hloov lub roj teeb thiab kho qhov ntim los ntawm ITC thiab CIC.
* Kev hnov ​​​​mob hauv pob ntseg AIDS ntawm tib qib thiab hom muaj kev lag luam ntau dua li ITC thiab CIC.

Hais txog ITE Hearing Amplifier

1,6 lub hauv paus qauv ntawm ITE lub suab nrov amplifier

a. Microphones: tau txais lub suab thiab hloov mus rau hauv daim ntawv ntawm hluav taws xob tsis muaj zog, uas yog, hloov suab lub zog rau hauv hluav taws xob.

b. Amplifier:

amplifying hluav taws xob teeb liab (transistor amplifier circuit).
c. Lub mloog pob ntseg:

converts hluav taws xob signals rau hauv suab, piv txwv li hluav taws xob lub zog rau hauv suab zog.
d. Pob ntseg pwm (earplug):

nws yog muab tso rau sab nraud auditory kwj dej.
e. Volume tswj hloov.
f. Fais fab mov:

ib lub cell qhuav rau lub amplifier.

2, Acoustic yam ntxwv ntawm ITE hnov ​​suab amplifier

a. Kev them nyiaj mloog ntawm lub pob ntseg pob ntseg hnov ​​​​lus thiab lub pob ntseg pob ntseg lub suab nrov ntawm 1KHz, 2KHz thiab 4KHz yog 25-33dbHL, thaum lub rooj sib hais ntawm 250-500Hz yog 20-24dBHL.
b. Tib neeg auricle muaj cov nyhuv ntawm lub suab sau, ITE hnov ​​suab amplifier microphone nyob rau hauv pob ntseg, siv cov yam ntxwv physiological ntawm tib neeg pob ntseg, nyob rau hauv lub suab nrov amplifier tsis tso zis lub xeev, ITE hnov ​​suab amplifier microphone suab nce mus txog 10dB SPL, thiab cov Lub suab nrov tom qab pob ntseg tsis tuaj yeem siv lub suab sau suab nrov rau lub suab nrov.
