The 500 Hz tone-pip evoked ABRs are below.

• Where would you mark wave V for the left ear traces?  Keep in mind that wave V latency will prolong as you decrease intensity.  What is/are the role(s) for latency in tone-pip threshold estimation?

The audiologist did not run a control run, but subtracted the initial and replication runs to give an approximation of the control run. That is shown on the right bottom.

• Which right ear response(s) would you mark as being consistent with a present response?  Compare latencies between ears.
