Changes in click characteristics during ABR recording.

Unlabelled: Manipulation of auditory stimuli affect the ABR evoked potentials and aid the diagnosis, particularly in auditory neuropathy patients. Some patients with auditory neuropathy lose evoked otoacoustic emissions over time; in these cases, comparing responses to rarefaction and condensation clicks, and decreasing the stimulus rate can show an extended cochlear microphonism or yield an improved electric potential record.

Aim: To analyze the effect of these click manipulations on the records of potentials of patients with hearing loss as a form of improving the diagnosis.
