Dear Auditory list member
We are considering purchase of an OAE instrument for research use.
It is a quite demanding application as we want to measure DP
input/output curves in both normal and hearing impaired subjects.
The stimulus range will thus include both very high and very low
stimuli. We therefore expect rest DP artifacts from the microphone to
be a problem at the
high stimulus levels and equally at the low levels system noise may
be a limitation.
Apart from this we would prefer a relative flexible system.
Further we may consider measuring evoked potentials in the future.
For the moment we consider the following instruments:
- Intelligent Hearing Systems
- Tucker Davies Technologies, system III
- Otodynamics 288 or 292 (without capability of EP)
We would appreciate any feedback on these instruments or suggestions
of any other instrument that should have our interest.
