The ABR waveforms shown below were collected. The parameters were as follows.
Rarefaction click stimuli, 33.1 per second
30-1500 Hz filtering
2000 sweeps per run, artifact rejection enabled.

- Determine if the waveforms represent normal findings.
- Describe the click threshold and interpret it. What does it add to the diagnostic picture that OAE testing did not already elucidate?
- Critique the testing. Is it sufficient?
