MY-G055 Portable Diagnostic Audiometer
It 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 center and deaf training etc.
Can conduct all standard hearingaid test, Language hearing test and all special test that depend on structure.
The design of it 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.
3 output option:standard earphone(AC),bone conduction(BC) and special
be connected to free area megaphone or inserted earphone.
calibrate multiple types of earphone at the same time.
be use as mobile devices,and also as desktop.
keyboard to install and operate,so it’s very easy to handle.
Display:
There are two output LED on both side of the display,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 show“L” or “R” on the display. Test frequency would
show in the middle of the screen.If cover the opposite ear,it will show in the opposite side.
Technical Index:
Channel:Two independent channel
Frequency: Air conduction; Bone conduction and free sound field 11 standard
frequency,125-8000Hz,bone conduction 250-6000Hz,error less than 1%.
