Analysis is based on normative data entered in Tools|Options|ABR & ECoG Norms. The default norms used by HearAid are those used at Goulburn Valley Health, which were collected using a Bio-Logic® Navigator with these test parameters:


Alternating polarity click stimuli presented at 80 dBnHL


Click rate 11 Hz


High Pass filter 300 Hz


Low Pass filter 3 kHz


A single pass of the post-hoc digital filter


Insert earphones


If your ABR recordings are made with any other test equipment or parameters you MUST enter your own norms!

Click the Print Analysis button to generate an ABR report






The ABR analysis will have no validity unless you have entered norms in Tools|Options|ABR & ECoG Norms


The ABR analysis function is not intended to replace audiological clinical judgment and analysis!  You use this function at your own risk and HearSoft Pty Ltd accepts no liability or responsibility for diagnostic judgments made on the basis of the analysis results.
