Pass Criterion: Normal results would consist of Wave V responses for clicks at 25 dB nHL within a normal absolute latency range for the child’s age. Suprathreshold click testing should also include one average with condensation clicks and another average at the same intensity with rarefaction clicks to rule-out auditory neuropathy/dys-synchrony.
