500 Hz ABR

This was a two cycle rise, one cycle plateau, two cycle fall stimulus.

  • What is the total duration of a five-cycle, 500 Hz stimulus?
  • What is the expected latency of wave V for a tone burst 500 Hz ABR?

Note that the wave marked 5 was to a condensation stimulus and the one called 6 is to rarefaction polarity tone bursts (#8 is the summation wave.)

  • What is seen in the first 6-10 ms of the right ear trace?  What is the time interval between the peaks?
