TDH39 earphone, DD45 earphone, CIR55 insert and/or EARtone
3A/IP30 insert for Reflex measurements.
Probe earphone incorporated in the probe system for Reflex
measurements.
Connection of the air system to the probe.
Manual control of all functions.
Automatic reflexes:
- Single intensities
- Reflex growth
Automatic, 10 dB above threshold and manually controlled with
stimulus durations of 10 to 30 s.
Automated, first 300 ms from stimulus start.
3 electrodes. 50 cm
Switchable: Software will automatically switch mastoid and ground if
mastoid montage is used. So the user does not need to replace
electrode during testing.
