ITE Hearing Amplifier

Production Introduction

ITE Hearing Amplifier (XB-102)

Compared with ITC hearing amplifier and CIC hearing amplifier, 

the advantages of the ITE hearing amplifier are:

*Suitable for hearing loss range is wide, large output power;
*It is easy to install double microphones, sound picking coil and other accessories;
*It is easier to replace the battery and adjust the volume by ITC and CIC.
*In-ear hearing AIDS of the same grade and type are more economical than ITC and CIC.

About ITE Hearing Amplifier

1、6 basic strutures of ITE hearing amplifier

a. Microphones: receive sound and convert it into the form of electrical waves, that is, converting sound energy into electrical energy.

b. Amplifier: 

amplifying electrical signal (transistor amplifier circuit).
c. The earphone:

converts electrical signals into sound, ie electrical energy into sound energy.
d. The ear mold (earplug):

it is inserted into the external auditory canal.
e. Volume control switch.
f. Power supply:

a dry cell for an amplifier.

2、Acoustic characteristics of ITE hearing amplifier

a. The hearing compensation of the ear cavity hearing amplifier and the ear canal hearing amplifier at 1KHz, 2KHz and 4KHz is 25-33dbHL, while the hearing compensation at 250-500Hz is 20-24dBHL.
b. The human auricle has the effect of sound collection, ITE hearing amplifier microphone is located in the ear, using the physiological characteristics of the human ear, in the hearing amplifier without output state, ITE hearing amplifier microphone sound gain up to 10dB SPL, and the behind-ear hearing amplifier can not use the auricle sound collection function for sound gain.
