AD-105 is a kind of high-precision, economical and practical screening audiometer. It 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.
Test Function And Characteristic
1. Air conduction Pure tone test
2. Provide continuant,pulse voice and twitter
3. Noise masking for ear (narrowband noise)
4. Both sides independent sound track.
5. Built-in MIC, convenient to communicate with patients.
6. Humanizing sound intensity output extend button, to protect patient’shearing.
7. Can choose bone conduction test
8. Can choose air conduction test
