AD-104 is a kind of high-precision,economical and practical screening audiometer.Can use for hearing test when fitting high-end hearing-aid and visiting service.And also use for hearing condition test of school, industrial and mining enterprises,army, fahrschule, rehabilitation centre and deaf training etc.
AD-104 can conduct all standard hearing-aid test, Language hearing test and all special test that depend on structure.
The design of AD-104 is on the base of a advanced 24 pixels digital signal processing,can produce high quality signal,and own prodigious refractivity.
Easy operation process.Can show the current condition clearly.button and selector are all type of low noise.The voice level,frequency and other information could be showed on the display clearly.Language input signal can be provided by internal or external microphone.It has a function:when testing language hearing, masking signal and language signal can be provided to the ears at the same time,that is noise language testing.
There have 3 output option:standard earphone(AC),bone conduction(BC) and special output(SF),can be connected to free area megaphone or inserted earphone.
AD-104 can calibrate multiple types of earphone at the same time.
AD-104 can be use as mobile devices,and also as desktop.
AD-104 use keyboard to intall and operate,so it very easy to handle.
Display:
There are two output LED on both side of the disply,when the selected detection signal transfer to corresponding ear,the screen would show.During the audio detection,the up line of the display would show the strength that provide to left or right ear by dBHL ration.
When testing,the test ear would showon the disply. Test frequency would show in the middle of the screen.If cover the opposite ear,it will show in the opposite side.

Hp series hearing aid programmer and the usb interface of pc computer constitute a complete hp system. After set up hp system, you can read and write the data of hearing aid through the hearing aid software that provide by manufacturers.
GZ-0702 audiometer is a computer control hearing test equipment that combine by several functional modules. It¡¡¥s a Microcomputer hearing evaluation tool which develop base on hearing test and the Acoustic requirements of hearing-aid fitting.
GZ-0702 audiometer use for pure tone test,be suitable for hospital ENT diagnose and hearing-aid fitting,or clinical/family and outer ambulant hearing test.
Test could proceed by TDH39 air conduction.test signal including pure tone,pluse voice and warble tone.
GZ-0702 audiometer provide 11 air conduction test frequency point, frequency range from 125Hz to 8KHz,dB HL from 0 to 110.
GZ-0702 audiometer also provide 11 bone conduction test frequency point, frequency range from 125Hz to 8KHz,dB HL from 0 to 70(the standard is from 250Hz to 6000Hz).
All of the test data result could be automatic switch to pure tone audiogram and calculate patient¡¡¥s PTA value automatically.
