Audiometer is small, simple, all- Keyboard setup and operation. It records air conduction, bone conduction, speech, sound field,
White noise and narrow-band masking noise standard model testing and SISI, ABLB, Stenger, etc.
Special test, but also has the following features: O Fast boot self-test, supplemented by computer, making it fully in line with modern
Two independent channels can be ITERA hardware configuration to the following tests:
Use the keyboard buttons to set directly on the device parameters, and stored for later use.
Simple keyboard operation, easy to use. Test results can be quickly detected, large-screen liquid crystal display test results.
Air and free field frequency of 12 standard can be upgraded to 125-12500Hz 16000Hz, loudness -10 – 120dBHL.
Bone conduction 250-8000Hz, loudness -10 – 70dBHL. Error less than ± 1%.
Special Features: SISI test amplitude can be modulated 5, 4, 3, 1, 0.75, 0.50, 0.25 dB.
Output selectable air conduction headphones, bone conduction headphones, insert earphones, and free plug-in masking sound field.
Step can choose to 1dB, 2.5dB or 5dB 5dB step error is less than a continuous attenuation 1dB,
Stepping error is less than 2.5dB 0.75dB, step 1dB error is less than 0.3dB.
External input: CD drive or a microphone.
Built-in call microphone. Through the knob on the panel can be 0-110 dB SPL continuous adjustment.
Portable design, easy out for doctors audiometry.
The data transfer interface, and computer communications, and is compatible with NOAH, you can call directly into NOAH the test results.
